2-EHN Cetane Increase Calculator

August 27, 2025 FTE Leave a comment

This calculator is designed to predict the cetane number increase of diesel fuel when adding 2-EHN (2-Ethylhexyl Nitrate) or additives containing 2-EHN to diesel.

First, enter the base cetane number of the diesel you are using (e.g. 51).

Then insert the amount of additive you wish to use (e.g. 50ml), followed by the amount of fuel you wish to treat (e.g. 50L).

This example would represent a treatment ratio of 1:1,000.

Finally, insert the percentage of 2-EHN in the additive you are using. Pure 2-EHN would be 100, and a product that contains approximately 50% 2-EHN would be entered as 50.

100% Sustainable Aviation Fuel: Transforming the Future of Air Travel

May 5, 2025 FTE Leave a comment

The aviation industry is on a path towards major transformation to meet environmental standards by 2050, a goal driven by the projected doubling of jet fuel consumption. Achieving carbon neutrality is a central focus, and sustainable aviation fuel (SAF) stands at the core of this transformation. SAF aims to drastically reduce carbon emissions from both commercial and military aircraft, which rely heavily on conventional fossil-derived jet fuel.

Current jet fuels comprise two main components: aliphatic and aromatic molecules. Aliphatic molecules, similar to those in diesel fuel, can be sourced sustainably from plant materials. Aromatic molecules are more complex and crucial for maintaining fuel properties and system integrity. The challenge has been to provide aromatic molecules sustainably, which limits the incorporation of sustainable fuels due to the “blending wall.”

Researchers from MIT, led by Yuriy Román-Leshkov, are exploring innovative avenues to breach this blending barrier. Their research focuses on lignin, a natural material found in plants, using a new catalytic process to extract and convert it into valuable aromatic molecules needed for SAF. This new method uses a combination of ruthenium-based catalysts and molybdenum carbide to break down lignin into aromatic compounds effectively.

Preliminary tests show promising results, with the produced fuels demonstrating characteristics similar or even superior to traditional aviation fuels. The potential to use alternative feedstocks, such as pine or switchgrass, offers flexibility and could support various SAF production routes.

The team’s advancements offer the possibility of removing the blending wall, leading to 100% renewable jet fuel. This shift is critical as the aviation sector explores paths towards fully sustainable flight operations. Future decarbonisation of aviation heavily depends on these innovative fuels and their integration into carbon-efficient fleets.

Organisations like Air BP and Marathon Petroleum Corporation are essential in this journey, as their involvement can extend the transatlantic network of SAF distribution. This collaboration will be vital in achieving the set targets for using SAF blends and ultimately reaching net zero carbon emissions by 2050.

Such pioneering progress in sustainable aviation fuels is vital for reducing our climate impact, with each development marking a step towards more eco-friendly air travel and improved local air quality.

Buying Guide

When shopping for a DPF cleaner, we need to consider several important factors. The right product can extend the life of your diesel particulate filter and improve your vehicle’s performance.

Cleaning Method

Different cleaners work in different ways. Some are added to the fuel tank, while others are sprayed directly into the intake system.

Cleaning Method	Best For
Fuel Additive	Regular maintenance
Direct Spray	Severe clogging
Combined Formula	Complete system cleaning

Products with multiple cleaning functions tend to be more effective as they can address both DPF and turbo issues simultaneously.

Compatibility

Always check if the cleaner works with your specific vehicle. Most products list compatible engines on their packaging.

Not all cleaners work with all diesel engines. Using an incompatible product might damage your vehicle or void your warranty.

Application Frequency

Some cleaners are designed for regular use, while others are for occasional deep cleaning.

Regular maintenance products are typically used every 3,000-5,000 miles, while intensive cleaners might be used once or twice a year.

Value for Money

Consider the cost per treatment rather than just the bottle price. Some concentrated formulas may seem expensive but provide more treatments.

Products that clean multiple components (DPF, turbo, EGR) offer better value than single-purpose cleaners.

Environmental Considerations

Frequently Asked Questions

People often wonder which DPF cleaners work best and how to use them properly. Here are answers to common questions about diesel particulate filter cleaners to help you make informed decisions for your vehicle.

What are the top-rated additives for cleaning a diesel particulate filter?

Oilsyn CarbonCode DPF and Turbo Doctor ranks as the best DPF cleaner on the market due to its comprehensive cleaning capabilities. It not only cleans the DPF but also addresses turbo issues and carbon deposits throughout the engine system.

Archoil AR6400-D MAX comes in as our second choice, offering excellent regeneration support and soot reduction properties. It’s particularly effective for vehicles that frequently operate in stop-start conditions.

Other notable products include Liqui Moly Pro-Line DPF Cleaner and Wynn’s DPF Cleaner, both providing reliable performance at reasonable price points.

How does Oilsyn’s particulate filter cleaning treatment compare with other brands?

Oilsyn’s formula stands out for its multi-functional approach. While many competitors focus solely on DPF cleaning, Oilsyn targets carbon build-up in the turbo and throughout the exhaust system as well.

We’ve found it requires fewer applications compared to other brands, making it more economical in the long run despite a higher initial cost. Users report noticeable improvements in vehicle performance after just one treatment.

The product also contains lower levels of harsh chemicals than some competing brands, reducing potential harm to engine components over time.

What should I consider before purchasing a DPF cleaning additive for my vehicle?

Compatibility with your specific diesel engine model is essential. Check your vehicle’s manual or consult with a mechanic before using any DPF cleaning product.

Consider your driving patterns—if you mainly drive short distances, you’ll likely need a more powerful DPF cleaner as your vehicle doesn’t reach temperatures needed for natural regeneration.

Your vehicle’s age and mileage matter too. Older vehicles or those with higher mileage might require stronger formulas or more frequent applications.

Budget is another factor—cheaper options might seem appealing but often require more frequent use, potentially costing more over time than premium products.

How often should I use a DPF Cleaner?

Most manufacturers recommend using DPF cleaners every 2,000 to 3,000 miles for preventative maintenance. However, this varies based on your driving conditions and vehicle specifics.

Vehicles used primarily for short journeys should receive treatments more frequently—perhaps every 1,500 miles—as they rarely achieve the temperatures needed for automatic regeneration.

Watch for warning signs that indicate more immediate treatment is needed: decreased fuel efficiency, reduced power, or illuminated engine management lights. These symptoms suggest your DPF may be becoming clogged.

Buying Guide: How to Choose the Best Petrol Cleaner

What to Look For

When selecting a petrol cleaner, the most important factor is the active ingredients. Look for products containing polyetheramine (PEA), which is considered the most effective detergent for removing carbon deposits from fuel injectors and combustion chambers. PEA-based cleaners like those from Oilsyn, Archoil and Techron tend to deliver better results than simple solvent formulations.

Consider your engine’s age and condition. Newer engines with minimal deposits may benefit from lighter, maintenance-focused cleaners, while older engines with significant build-up require stronger formulations. Check that the cleaner is compatible with your fuel type – most modern cleaners work with E10 and E5 petrol blends commonly found in the UK.

Frequency of Use

Most petrol cleaners are designed for periodic use rather than continuous addition to your fuel. A typical recommendation is to use a cleaner every 3,000-5,000 miles or every 3-6 months, depending on your driving conditions. City driving with frequent stop-start conditions may require more frequent cleaning than highway driving.

Follow the manufacturer’s instructions carefully. Some products like the Oilsyn kit require using different bottles on separate fill-ups, while others can be added to a single tank.

Safety and Compatibility

Ensure the cleaner is safe for your engine’s components, including oxygen sensors, catalytic converters, and fuel system seals. Quality cleaners from reputable brands undergo extensive testing to ensure compatibility with modern engine management systems.

Avoid cleaners that make unrealistic claims. Stick to established brands that provide clear ingredient lists and usage instructions. If you have a high-performance or modified engine, consult with a specialist before using any fuel additives.

Frequently Asked Questions

How often should I use a petrol cleaner?

Most petrol cleaners should be used every 3,000-5,000 miles or every 3-6 months, depending on your driving conditions and the specific product. City driving with frequent stop-start conditions may require more frequent cleaning than highway driving. Always follow the manufacturer’s recommendations for your specific cleaner.

Can petrol cleaners damage my engine?

When used as directed, quality petrol cleaners from reputable brands are safe for modern engines. However, overuse or using incompatible products can potentially damage seals, gaskets, or sensors in older engines. Always check compatibility with your vehicle and follow usage instructions carefully.

Will I notice immediate results after using a petrol cleaner?

Results vary depending on your engine’s condition and the cleaner used. Some drivers notice improved idle quality or throttle response within a few miles, while others may need to complete a full tank or two before seeing benefits.

Can E10 Cause A Misfire?

Here’s the surprising connection between E10 fuel and engine misfires.

E10 can cause misfires in incompatible vehicles through fuel system contamination and water absorption.

Ethanol’s hygroscopic properties attract moisture causing irregular combustion patterns.

Water contamination reduces octane rating and creates lean fuel mixtures leading to misfires and rough running.

Check vehicle E10 compatibility immediately if experiencing misfires after the fuel switch, and revert to E5 super unleaded if problems persist.

I’ve seen firsthand through countless consumer messages at Fuel Tech Experts how crucial but problematic these filters are.

A DPF is a device in diesel vehicles that traps and stores soot particles from the exhaust gas.

This helps reduce pollution.

To keep it from clogging, the DPF undergoes a process called regeneration, where the trapped soot is burned off at high temperatures, around 600°C.

It’s vital to maintain it properly.

And behind that, the vehicle’s ECU plays a pivotal role.

It monitors the soot load and triggers regeneration when conditions are ideal, like when the exhaust reaches the necessary temperature during highway driving.

Miss these conditions, and the DPF can clog, leading to warning lights and performance issues.

If you’ve ever faced DPF troubles, I’d love to hear about your experiences.

Keep an eye out for more insights coming your way!

What does a DPF do?

What does a DPF do? Ever wondered what happens to all that black smoke your diesel engine used to puff out?

Since founding Fuel Tech Experts, I’ve seen how Diesel Particulate Filters keep our air cleaner by trapping soot.

A DPF captures soot from your diesel engine’s exhaust, preventing it from reaching the atmosphere.

As it fills up, the DPF needs to burn off the soot through a process called regeneration, which happens when the exhaust gets hot enough during a drive.

The ECU monitors when the DPF needs regenerating. It checks exhaust pressure, back pressure, and temperature to trigger the process.

If conditions aren’t met, the soot stays, potentially causing blockages.

Have you noticed your DPF light coming on more frequently?

Get the engine up to full operating temperature and keep the revs above 2500 for 10 minutes or more to force an active regeneration.

I hope you find this explanation helpful and let me know if you have encountered any DPF issues.

How does a DPF work? Ever wondered how your car’s Diesel Particulate Filter, or DPF, helps keep the air cleaner?

In my work with engineers and fleet operators, I’ve seen just how crucial this component is.

A DPF traps soot particles from your exhaust gases, preventing them from reaching the atmosphere.

It stores these particles until regeneration occurs, essentially burning them off at high temperatures.

To help this process, ensure your vehicle regularly reaches the necessary operating conditions.

The DPF relies on reaching exhaust temperatures of around 600°C for effective regeneration.

If your car often takes short trips, consider longer drives at higher revs to help maintain the filter’s efficiency.

Hope this sheds light on how your DPF works.

If you’ve dealt with DPF issues, feel free to share your experience.

What is a DPF system?

Ever wondered why your diesel keeps asking for a little extra attention?

Running Fuel Tech Experts, I’ve seen countless drivers puzzled by the Diesel Particulate Filter, or DPF, system.

The DPF is part of your car’s emissions system, designed to catch soot from the exhaust before it hits the air.

It’s crucial for keeping emissions in check.

If your DPF warning light comes on, it’s often a sign that the filter is full and needs a clean or a regeneration.

Follow it a step further, the DPF needs high temperatures to burn off the soot, a process called regeneration.

This usually happens during longer drives when the exhaust is hot enough.

If you miss these conditions, soot builds up, and you might see that pesky warning light.

Have you had your DPF light come on?

Let me know how you dealt with it.

Do all diesel cars have a DPF?

Do all diesel cars have a DPF?

Not every diesel car has a Diesel Particulate Filter (DPF), and having spoken to many customers over the years with DPF issues, many wish they hadn’t!

Modern diesel cars do come equipped with a DPF to reduce soot emissions, but older models or certain markets may not have one.

If your vehicle was made before 2009, it’s possible it doesn’t have one.

DPFs are mandatory today due to stricter emissions regulations.

They trap soot and require high exhaust temperatures to regenerate efficiently.

This cycle helps keep emissions within legal limits.
