Signs that your diesel engine needs cleaning

Recognizing the signs that your diesel engine requires cleaning is the first step in maintaining its optimal performance. One of the most common indicators is a noticeable decrease in fuel efficiency. As deposits build up, the engine has to work harder to overcome the increased resistance, leading to higher fuel consumption.

Another sign is a reduction of power or poor acceleration. Clogged fuel injectors and carbon buildup can impair the engine’s ability to deliver the necessary power, resulting in a sluggish and unresponsive driving experience. You may also notice increased exhaust emissions, indicating incomplete fuel combustion due to engine contamination.

Unusual engine noises, such as knocking or rattling, can also indicate that your diesel engine needs cleaning. Additionally, if you’ve noticed a decline in your engine’s overall smoothness and responsiveness, it’s a clear indication that it’s time to address the issue with a reliable diesel cleaner.

Benefits of using a diesel cleaner

Using a high-quality diesel cleaner can provide numerous benefits to your engine, ultimately improving its performance and extending its lifespan. One of the primary advantages is the restoration of fuel injector efficiency. Diesel cleaner formulations are designed to dissolve and remove deposits on fuel injectors, allowing for better fuel atomization and improved combustion.

This, in turn, increases power output, as the engine can extract more energy from the fuel. Improved fuel combustion also results in better fuel economy, as the engine operates more efficiently and requires less fuel to produce the same power.

Another significant benefit of using a diesel cleaner is the reduction of harmful emissions. By removing deposits and restoring proper fuel combustion, diesel cleaners can help lower the levels of particulate matter, hydrocarbons, and nitrogen oxides in the exhaust, contributing to a more environmentally friendly driving experience.

Furthermore, regular use of a diesel cleaner can help extend your engine’s lifespan by preventing new deposits and protecting critical components from wear and tear. This can lead to fewer costly repairs and a more reliable and durable engine, ultimately saving you money in the long run.

How to choose the right diesel cleaner for your engine

Selecting the right diesel cleaner for your engine is crucial to ensure optimal performance and long-term protection. When choosing a diesel cleaner, consider factors such as how much cetane they deliver, cleaning capability, lubricity, and more.

It’s also important to ensure that the diesel cleaner is compatible with your engine type and fuel system. Most cleaners are formulated for specific fuel types (petrol or diesel), so it’s essential to check the manufacturer’s recommendations to ensure a proper fit. Failure to use a compatible diesel cleaner will likely result in disappointment, and the detergent type and structure will be different from those of a petrol cleaner.

In addition to cleaning capabilities, consider diesel cleaners that offer benefits such as improved lubrication, corrosion protection, or enhanced fuel stability. These added features can further contribute to the overall health and longevity of your diesel engine.

Step-by-step guide on how to use a diesel cleaner

Using a diesel cleaner is a straightforward process that can be easily incorporated into your regular engine maintenance routine. Here’s a step-by-step guide to ensure you get the most out of your diesel cleaner:

Determine the appropriate amount of diesel cleaner to use based on your fuel tank size and the manufacturer’s recommendations. Typically, a single dose of diesel cleaner is sufficient for a full tank of fuel. All diesel cleaners will have instructions on the package label.
Ensure that your fuel tank is less than half full before adding the diesel cleaner. This will help the cleaner mix thoroughly with the fuel and maximize its effectiveness.
Carefully pour the diesel cleaner into the fuel tank, taking care not to spill or splash the product. Some cleaners may come with a specialized dosing cap or funnel to make the process easier.
Drive your vehicle as you normally would, allowing the diesel cleaner to get to work. Depending on the severity of the deposits, it may take several miles for the full benefits to be realized. High-end diesel cleaners will show signs of improvement within a few miles of driving.
Repeat the process every few thousand miles or as recommended by the diesel cleaner manufacturer to maintain a clean and efficient engine.

Remember to always follow the manufacturer’s instructions and safety guidelines when using a diesel cleaner. Proper usage and regular maintenance will help you get the most out of your diesel engine and extend its lifespan.

Common misconceptions about diesel cleaners

Ester Fuel Lubrication

Diesel Additive Lubricants – Mono Fatty Acid vs Esters vs Orisyn® Ester

November 2, 2024 FTE 2 Comments

It may surprise you to learn that many diesel additives, including well-known brands, are still using mono fatty acid lubricants in their diesel additives.

Why is this an issue? Not only is fatty acid very old and cheap technology, but it offers zero lubrication benefit to UK or EU EN590 specification diesel, where the minimum ASTM D975 wear scar test is 460 µm. Mono fatty acids are designed to reach this level but not improve on it.

But it is worse than this. Many diesel additives utilize 2-EHN to raise the cetane level to improve combustion quality and torque output. However, mono fatty acids do not work in the presence of 2-EHN. They cancel one another out, resulting in no HFRR improvement. In some instances, lubrication is worse than it was before using the diesel additive, and customers are completely unaware that they are using a diesel fuel additive with inferior lubricity. This includes established brands from the UK, Germany, and beyond. They sell thousands of products daily, mostly through platforms like Amazon. Customers rave about them and leave great reviews without any idea that they are simply buying a diluted 2-EHN cetane improver with a cheap lubricant. And possibly in a fancy-spouted bottle, depending on the brand. Seriously, most of them don’t even use detergents. These products are manufactured at under £2 and then sold to you for £13+ for 500ml.

Any diesel additive with a little 2-EHN will improve performance, so it must be a great product, right? What about what you can’t see, such as the lubrication and protection, cleaning, and so on? As a consumer, it is important to understand what is in the diesel additive you are putting in your engine.

This is where Ester lubrication comes in. Certain ester technologies do perform in the presence of 2-EHN. They complement each other perfectly and are much more likely to deliver an improved HFRR response. At the very least, 2-EHN based diesel additives with ester will not lower lubricity.

There are still limitations with esters though. And that is when used with summer specification diesel. This is because high-quality summer diesel is usually much more lubricious than the standard 460um limit, and even ester lubricants struggle to provide an advantage in these fuels. This is where Orisyn Ester enters the party. It is one of the few lubricants that provides a tangible improvement, even in the most lubricous diesel fuels. It is unique to Oilsyn and not found in any other diesel fuel additive. It is also much safer than 2-stroke oil, which can foul diesel injectors and emission control system components such as EGRs and DPFs.

Orisyn does have a downside: It is expensive and requires 2-3x the dose rate of conventional fatty acid and ester lubricants. However, that is Oilsyn’s problem, not yours! Oilsyn still manages to put the product to market at a cost comparable to competitor products.

To summarise, I like the ester used in the UK/EU Archoil diesel additives. It is a high quality ester that provides consistent lubrication, and is not found in any other aftermarket diesel additive. However, I like the Orisyn ester in the Oilsyn Diesel Additives even more as it provides additional lubricity in the most lubricious diesel fuels.

EGR Cleaning & Maintenance

EGR Delete Issue from a Concerned Customer

October 11, 2024 FTE Leave a comment

This is a recent message I received from a customer regarding an EGR delete carried out on his vehicle.

“I have a VW T5.1 and the coil light illuminated a couple of months ago. I took it to a garage who diagnosed a faulty EGR valve and Cooler. I took advice from friends and family to have the EGR deleted at a cost of £130 rather than the quoted £1100 to replace the EGR valve and cooler.

Within 100 miles, the DPF regen light came on, followed by limp mode. I took it back to the remapping company who forced the regen and said it was fine.

I drove up to Inverness (400 miles) where the DPF regen light came on again, and then the van went into limp mode. A remapping garage in Inverness forced it into regen mode again and I managed to get home before the DPF came on again. I took the van to a specialist DPF cleaner company who stated that DPF was full of ash and soot and cleaned it out. I drove the van for a week (around 200 miles) before the DPF regen light came on again.

Before I spend a lot of money at the VW garage, do you have any thoughts/advice?”

Unfortunately, this is not uncommon. Whoever worked on this car failed to investigate the root cause of the problem, and forcing the DPF to regen every few hundred miles is only addressing the symptoms.

The engine ECU will not permit a passive DPF regeneration if a problem is detected. This would include any anomaly it detects with the EGR function. If the EGR delete has not been coded correctly, then the DFF won’t be able to regenerate on its own. Writing the warning light/code out of the software is not always sufficient as the ECU needs to “see” via various sensor outputs, that the EGR is operating correctly. If the DPF problem started after the EGR deletion, then that should be investigated first.

It is also worth noting that it is an offense to use a vehicle with any part of the emission control system modified to alter the emissions standards it was originally designed to meet. I hope the customer was advised of this.

Fuel Quality, Fuel Saving

Cheapest Fuel – How to Save Fuel by Buying the Cheapest and Converting it into Premium Fuel

October 9, 2024 FTE Leave a comment

Pump prices are rising, and those with electric vehicles have started feeling the pinch with an unprecedented rise in electricity.

There is something you can do.

Premium or Super fuels usually deliver better fuel economy than standard fuels, even from the same brands. For example, V-Power diesel will provide more performance and MPG than standard Shell diesel fuel. But, it is more expensive.

The solution:

Buy the cheapest pump fuel you can find and then use a fuel additive to convert it into premium fuel. A high-quality additive will typically cost a fraction of the price of buying premium fuel at the pump but deliver similar benefits. * Except for higher octane with gasoline. If your vehicle requires or responds better to higher-octane gasoline, continue using it. Just find the cheapest brand available.

Petrol Additive – Ensure any petrol additive contains the following:

Proven PORT and GASOLINE DIRECT INJECTION (GDI) detergent pack, particularly if you drive a modern vehicle with a GDI fuel system.
High-performing fuel system / upper cylinder lubricant.
Combustion improvement function.

Although the above won’t make up for any shortfall in octane, they will improve fuel economy by maintaining a cleaner fuel system, reducing upper cylinder friction, and improving combustion quality.

Diesel Additive – Ensure any diesel additive contains the following:

2-EHN cetane improver that delivers a minimum 3-point increase per dose. Using 2-EHN alone will reduce fuel lubricity and not provide the maximum available fuel savings.
High-performing Ester (or similar) fuel system / upper cylinder lubricant with an HFFR no higher than 250. Disregard any product using mono-acid lubricants as they underperform with standard EN590 diesel fuel.
Cleaning and combustion improvement technology.

Any diesel product that meets the above three criteria will convert regular diesel into Super diesel and improve fuel economy when added to a standard, low-cost diesel.

Car Emissions, Hybrids

What’s the Difference Between Hybrid and Gasoline Cars?

November 2, 2022 FTE Leave a comment

Gasoline cars have been around for more than a century and what Carl Benz started as an endeavor became the most common means of transportation. Since then, there have been dozens of new auto manufacturers, and the technology has advanced rapidly. More unique engine configurations, refined transmissions and suspension systems, and betterment in almost every aspect occurred. But the real change occurred after nearly 100 years when Toyota unveiled their first Hybrid car, the very popular Toyota Prius. Thanks to its unbelievable fuel economy, controversially silent powertrain, and fewer emissions, it had everybody in its awe. It was an all-new concept with a grand promise for the future of greener mobility.

Although hybrid technology has matured a lot since its inception and the world is moving onto electric cars, it remains the most striking development in the auto industry. Let’s review some of the most significant differences between hybrid and gasoline cars and relive the nostalgia of technology transformation.

Powertrain and Technical Specs

Hybrid cars are similar to gas cars, but there is one significant difference, an electric motor and a battery. The engine is augmented by a battery-powered motor which supplements the available power. Not only does it enhance fuel efficiency, but it also reduces carbon emissions and offers a more refined driving experience. The motor runs all the time, especially at lower speeds, to keep the load off the engine and improve the mileage. The driver can also choose to drive in hybrid, electric-only, and engine-only modes.

The technology behind gasoline cars is straightforward. They have an internal combustion engine mated to a manual or automatic transmission, supported by a suspension setup. The engine has many other periphery parts, such as a timing belt, alternator, radiator, and fuel system, emission control system, for it to function. The engine uses gasoline to deliver a combustion process that generates power to rotate a driveshaft, which is directed to the wheels via a transmission. The technical specs and ICE (internal combustion engine) technology has been refined immensely over time, with the introduction of advanced fuel injection system, emission systems, and low viscosity oils to reduce friction.

Mileage and Fuel Efficiency

One aspect setting these types of cars apart is the fuel economy and mileage. Gasoline cars are great to drive but are known gas-guzzlers unless you opt for the more refined, smaller-capacity engines.

Hybrid cars changed this and offered improved fuel efficiency without sacrificing drivability or refinement. With the motor and engine running in synergy, the hybrid can offer greater mileage with the plugin variant ideal for short journeys running solely on battery only.

Service and Maintenance

Maintenance and servicing of the gas and hybrid cars can be different, and one has to be meticulous with their hybrid car, in contrast to an ICE car. Hybrid cars feature more complex technology, additional parts, and an intermittently running motor powered by lithium-ion batteries. Auto manufacturers have sketched an exact maintenance schedule for hybrid vehicles that must be followed to ensure long-term durability and optimal performance. A few of the essential maintenance steps involved in hybrid cars’ servicing can include a battery check, calibration, and possible recalibration of the electric motors.

On the other hand, gasoline cars are simpler to maintain, replacing fewer wearing parts every few thousand miles, mainly engine oil and filters.

Utility and Dependability

Gasoline cars have been around for much longer than hybrids, and needless to say that they served the purpose very well. Long-term durability, easy usage, a wide range of applications, and, more recently, longer service intervals.

Hybrid cars can offer excellent dependability, thanks to hybrid technology and improved fuel economy, in an eco-friendlier manner. Then came the plug-in hybrid vehicles, where batteries could be charged from home and allow short trips on battery-only power.

Some PHEVs (plug-in hybrid electric vehicles) have been tested and are known to offer up to 75 mpg in fuel economy. Many also use regenerative braking, the technology that converts the kinetic energy of the brakes into electrical energy and charges the battery while you drive.

Emission Standards

There is no comparison in this department. Hybrid cars have two main goals, fuel economy and greener functioning. These cars generate substantially fewer carbon emissions than gasoline cars and are touted as the stepping stone toward zero-emissions mobility. This helps considerably with car tax, especially with company-supplied cars.

Gasoline cars are notorious for creating pollution and emitting toxic gases into the environment. Diesel cars are even more harmful to the environment and are slowly being phased out in favor of more environment-friendly hybrid and electric vehicles on a global scale.

Types

Unlike gasoline cars, Hybrid cars are offered in different types and come with different technologies, mostly based on the battery type used in the car. Types of hybrid cars include;

Conventional hybrid
Mild hybrid
Plug-in hybrid

Summary

	Gasoline	Hybrid
Fuel Efficiency	Poor	Good
Emissions	Poor	Poor-Good
Complexity	Average	High
Performance	Good	Good
Maintenance	Average	Average
Price	Average	Above Average

Race Fuel

Race Fuel Composition and Its Effects on the Engine

October 15, 2022 FTE 1 Comment

It’s a common misconception that race fuel is an otherworldly, specially formulated concoction. Some think it is a unique blend of chemicals that a regular road-going car cannot handle. However, the reality is quite different.

We will try to separate the truth from the lies and unravel the secrets behind race fuel, its composition, and its effects on an engine.

For the sake of this argument, we will choose Formula 1 as our case study, since it is, after all, the pinnacle of motorsports. No other racing series comes even close to the level of innovation and engineering promoted by Formula 1. Therefore, it is only fitting that the series be chosen as an example.

What is Race Fuel?

In simple terms, race fuel is a highly specialized variant of regular fuel used in motorsport competitions across the globe. However, its composition and nature vary from one racing series to another.

Usually, race fuel has a high octane rating and it consists of additives that support performance. But various motorsport series regulate their race fuel and Formula 1 is no different.

So, what is unique about race fuel? Let’s look at its composition from the F1 perspective.

Race Fuel Composition 300

The race fuel must have the following composition to be declared legal.

Property	Units	Min	Max	Test Method
(RON+MON)/2		87		ASTM D 2699/D 2700
Oxygen	wt%		3.7	Elemental Analysis
Nitrogen	mg/kg		500	ASTM D 5762
Benzene	wt%		1	GC-MS
DVPE	kPa	45	60(1)	EN13016-1
Lead	mg/l		5	ASTM D 3237 or ICP-OES
Manganese	mg/l		2	ASTM D 3831 or ICP-OES
Metals (excluding alkali metals)	mg/l		5	ICP-OES
Oxidation Stability	minutes	360		ASTM D 525
Sulphur	mg/kg		10	EN ISO 20846
Electrical conductivity	pS/m	200		ASTM D 2624
Final Boiling Point	oC		210	ISO 3405
Distillation Residue	%v/v		2	ISO 3405

Such detailed guidelines show the precise measurements of the compounds involved in creating race fuel. But one thing is missing from the table, which has only recently been added to Formula 1.

We are talking about ethanol and F1’s push towards a sustainable future. The racing series has declared that from 2022 onwards, race fuel must have 10% ethanol in the mixture. In other words, F1 cars must run on E10 fuel and cut down on their dependence on pure gasoline. The percentage of ethanol or bio-fuels will increase even further from 2025 till the entire composition of race fuel consists of sustainable compounds.

But why take such radical steps?

Well, Formula 1 is trying to save the environment by shifting their cars to sustainable fuels. They also know that their technology transfers quite quickly to road cars. Therefore, if they make the change now, future cars would become more environmentally friendly. The fuel they use will be ‘greener’ and the earth as we know it, might be spared from adopting EV technology and its side effects.

Bio-fuel Ethanol and its source 100

The interesting thing about ethanol is that it is extracted from various plant materials like corn starch or other non-edible fibrous materials. You do not have to cut down mountains or drill deep holes to extract this soon-to-be precious liquid.

In other words, it is a non-exhaustive renewable source which does not produce harmful carbon gases on combustion.

The process to produce ethanol is completed in a lab after which the pure ethanol is mixed with the gasoline to make the E10 fuel we can see in F1 cars today.

Ethanol and its effects on the engine 200

The introduction of ethanol in the mix is a good omen, right? After all, the world would benefit from manufacturers tuning their engines to support ethanol and then that technology would transfer to road cars. It sounds too good to be true, and it is!

You see, ethanol might be good for the environment but it is not suitable for a gasoline engine. So, the idea to introduce an increasing amount of ethanol in fuel looks good but it isn’t practical as of now. Perhaps, with the regulations in F1, we will get to see some improvements in the engine’s ability to adapt to such a change. But quick results won’t be possible and they might not be possible at all without sacrificing performance.

Currently, commercial fuel has 3 to 5% ethanol included in the mixture and that works. But experts believe that a 10% increase could do considerable damage to engine components. Let alone a 15% or 30% increase in composition. That’s because ethanol dries up the engine from the inside, causing damage to the injectors, fuel pipes, hoses, rubbers and other materials.

The last thing you would want is to do irreversible damage to your car. So, what is your way out?

Luckily, F1 teams and fuel suppliers have taken to the challenge and found ways to work around the issue. The Formula One racecars are a living example of how a 10% ethanol composition is efficiently possible and even sustainable.

You can take a look at the Ferrari and Shell partnership in the current F1 season. The Italian team feared a 20 HP loss due to the changes they made to their engine’s combustion chambers. The latter was necessary to mitigate the effects of the E10 fuel.

However, the team recently cut down the gap and found a way to regain the lost 20 HP, thanks to Shell. The renowned fuel supplier has found a way to make E10 fuel more powerful and efficient. In fact, Shell’s E10 fuel is expected to get even better in the coming few months. They could perfect the E10 fuel in a few years to make it commercially viable.

Unfortunately, Shell is tight-lipped on how they managed to extract 20 extra horsepower from their E10 fuel just by researching the chemicals and compounds. They do not want their rivals copying their research. But all the teams may come out with a different solution to the problem and find another unique way to tackle E10 fuels.

One thing is for sure, whatever hacks the fuel suppliers employ during this season and the next will come in handy in the future. We will know for sure once regular fuel would be forced to run a 10% ethanol composition.

Can race fuel be used in a road car?

We have already established that race fuel is quite similar to regular fuel. But if that is true, can you use race fuel in your daily driver?

The answer is no, you shouldn’t put race fuel in your car. First off, you won’t be able to find it too easily. But if you do get your hands on some, it would be dangerous for yourself and your car to run on specialized fuel.

The biggest reason is that modern cars are designed to run on unleaded fuel. A racecar, on the other hand, is designed to run on leaded fuel. You can see the composition for race fuel in the section above and there you will find that a maximum of 5 mg/l of lead is allowed in race fuel.

Meanwhile, your road-going sedan needs unleaded fuel, meaning you can’t even put a small amount inside. Otherwise, you would mess up the entire engine and the costs of repair would shoot through the roof.

Conclusion

Ethanol is becoming an increasing factor in racecars and it will soon be a concerning factor for road cars. We will see innovations in technology, like the one we saw by Shell. But the fuel part of the equation won’t be enough unless engines are redesigned and changed alongside it.

The efforts by Shell, its rivals as well as engine manufacturers would change the world as we know it! Perhaps, we will make it in time to stop total EV domination. Maybe we won’t make it, but the revolutionary research in fuel technology would help reduce carbon emissions a bit further. The trucks, ships and other large vehicles would be able to do their work without producing carbon emissions.

Fuel System Cleaning

Fuel Injector Cleaners and Polyether-amine

September 2, 2022 FTE 4 Comments

Back in 2008, I was the first to publicly highlight the significance of PEA (polyether-amine) chemistry for fuel system cleaning. Since then, polyether-amine has become one of the most discussed topics across automotive forums and websites. Before that, almost nobody outside the additive industry had heard of it.

PEA remains the most effective detergent chemistry for removing carbon deposits from the combustion chamber and the high-temperature areas of the fuel system. Results are often immediate, with noticeable improvements in engine performance within just a few miles after treatment, especially where injector or combustion-chamber deposits have accumulated.

To be fair, cheaper treatments based on polyisobutylene-amine (PIBA) can do a decent job of cleaning conventional port fuel injectors, much like any basic solvent-based cleaner. Where they struggle is with modern high-pressure fuel systems and the stubborn carbon that forms inside the combustion chamber. The reason most products avoid using PEA is simple: high-quality polyether-amine costs significantly more than these alternative chemistries.

More advanced products will use multiple cleaning technologies, such as Oilsyn’s PEATeach Petrol Dr, CarbonCode Diesel Dr, and CarbonCode DPF & Turbo Cleaner. They use modern cleaning chemistry combined with PEA and other cleaning functions to deliver a more thorough clean throughout the system.
