Expert Reviews and Recommendations for Optimal Diesel Performance

DPF cleaners help maintain your diesel vehicle's particulate filter, preventing costly repairs and performance issues. Diesel Particulate Filters (DPFs) trap soot from exhaust gases, but they can become clogged over time. A quality DPF cleaner breaks down carbon deposits and soot, extending the life of your filter and improving fuel efficiency.

We've noticed that many drivers wait until warning lights appear before addressing DPF issues. Regular use of a DPF cleaner can prevent these problems altogether. These products come in different formulations – some work through the fuel system while others require direct application to the filter itself.

When choosing a DPF cleaner, pay attention to the application method, compatibility with your vehicle, and whether it offers additional benefits like turbo cleaning. The concentration of active ingredients and how frequently you need to use the product are also important factors. Let's explore the best DPF cleaners currently available to help keep your diesel engine running smoothly.

Best DPF Cleaners

We've carefully selected five of the top DPF cleaners available on the market today. Our comprehensive list features products that help remove soot buildup and restore your diesel particulate filter to optimal performance. Oilsyn CarbonCode DPF and Turbo Doctor stands out as our top choice due to its exceptional multi-function cleaning capabilities, while Archoil AR6400-D MAX secures a well-deserved second place.

Oilsyn CarbonCode DPF Cleaner

We consider the Oilsyn CarbonCode Complete Diesel DPF Cleaner a wise choice for vehicle owners looking to restore engine performance and help eliminate warning lights due to its comprehensive cleaning formulation, which comprises four cleaning technologies in one package.

Pros

Cleans multiple systems including fuel system, DPF, turbo and catalytic converter
High-Strength formula that removes carbon deposits
Contains protective lubricants to safeguard engine components

Cons

Higher price point than basic cleaners
Requires concentrated dosage for maximum effectiveness

This 400ml bottle of Oilsyn CarbonCode uses advanced Fueloxy carbon removal technology to tackle stubborn deposits throughout your diesel engine system. The formula works quickly to clear blocked DPFs, clean catalytic converters, and remove carbon buildup from turbos – addressing multiple issues with a single product.

Many drivers report overall performance improvments as well as restored DPF function. This is because CarbonCode contains multiple detergent technologies that address the fuel system and combustion chamber too, not just the DPF and Turbo. The product contains Oilsyn Modified Ester lubricant that protects your fuel system during the cleaning process. This protection is vital when breaking down tough carbon deposits.

We appreciate that this cleaner meets important standards including BS EN590 and REACH compliance. It's designed for easy use – simply pour into your fuel tank before filling up. While not every user experiences dramatic results, most report eliminated warning lights and smoother engine performance, making this a solid investment for diesel owners facing DPF issues.

Archoil DPF Cleaner

Archoil AR6400-D MAX offers a comprehensive cleaning solution for diesel engines with impressive results for DPF and fuel system maintenance.

Pros

Cleans multiple engine components including DPF, CAT, and fuel injectors
Users reports it has restored fuel economy and engine performance noticeably
Includes professional support and emissions pass guarantee

Cons

Higher price point than some competitors
May need multiple treatments for severely clogged systems

We've found that the Archoil AR6400-D MAX stands out as a powerful solution for diesel vehicle owners facing DPF issues. The product works throughout the entire fuel system, tackling carbon deposits in the particulate filter, EGR valve (results vary), and injectors. Many users report smoother engine performance after just one treatment.

The formula contains a special blend of detergents and lubricants that help remove stubborn carbon buildup. This isn't just about cleaning—it also adds ester lubrication and cetane improvement. These features help restore lost power while potentially improving your vehicle's chances of passing emissions tests.

What makes this product particularly appealing is the support backing it. Archoil offers professional guidance and a performance guarantee, which provides peace of mind for drivers. The 400ml bottle is enough for several treatments depending on your vehicle size, but a full can to a full tank of fuel is advised for best results. Though not the cheapest option available, the comprehensive cleaning action makes it worth considering for diesel owners experiencing warning lights or reduced performance.

Check Price

Redex DPF Cleaner

Redex DPF Cleaner is a reliable solution for diesel vehicle owners looking to maintain their particulate filters without expensive garage visits.

Pros

Reduces soot build-up by lowering burn temperature
Simple pour-in application through fuel filler
Prevents warning lights and costly repairs

Cons

Requires regular use for best results
May need multiple treatments for severe blockages
Works gradually rather than instantly

This diesel particulate filter cleaner from Redex tackles one of the most common issues diesel car owners face today. The product works by lowering the temperature at which soot burns in your DPF, allowing normal driving to clear blockages without requiring extreme engine temperatures or garage intervention.

We find the application process straightforward and mess-free. Simply pour the 250ml bottle directly into your fuel tank before filling up with diesel. The specially designed bottle makes this process clean and simple, with no need for funnels or other tools.

Regular maintenance is key with DPF issues. Adding Redex every 2-3 tanks of fuel can prevent problems before they start. Many users report success in clearing existing blockages and warning lights, potentially saving hundreds of pounds in garage repair bills. With over a century of experience, Redex has established itself as a trusted brand in the automotive maintenance sector.

JLM DPF Spray

The JLM Diesel DPF Cleaner provides a practical solution for maintaining diesel particulate filters without requiring professional servicing.

Pros

Fast-acting formula dissolves soot deposits effectively
No dismantling required for application
Helps improve fuel efficiency and engine performance

Cons

Mixed results depending on severity of DPF clogging
Single application may not be sufficient for heavily clogged filters
Some users report no improvement after use

This aerosol spray offers diesel vehicle owners a straightforward approach to DPF maintenance. The concentrated formula works by breaking down and removing soot deposits that accumulate in the particulate filter. Many users find it significantly cheaper than professional cleaning services that can cost upwards of £250.

Application couldn't be easier, as the product comes in a handy spray can that allows direct application to the DPF without any need to remove parts. We appreciate how this makes it accessible for everyday motorists who might not have advanced mechanical skills or special tools. Regular use can help extend the service life of your DPF and potentially save costly repairs down the line.

The environmental benefits shouldn't be overlooked. A clean DPF means reduced harmful emissions from your vehicle. While not every user experiences dramatic results, the relatively low cost makes it worth trying before resorting to more expensive options. For those experiencing warning lights or reduced performance due to a partially clogged DPF, this cleaner provides a reasonable first step in troubleshooting.

Wynn's DPF Cleaner

Wynn's Diesel Particulate Filter Cleaner offers a professional-grade solution for severely clogged DPFs when standard regeneration methods have failed.

Pros

Effectively dissolves stubborn soot in heavily clogged DPFs
Ready-to-use formula requires no dilution
Biodegradable composition safe for all DPF types

Cons

Requires filter removal from vehicle
Two-hour soak time needed for best results
Price point higher than basic DPF additives

This heavy-duty workshop cleaner targets DPFs with over 70% soot loading where conventional methods aren't working. Its powerful formula penetrates deep into the filter structure, breaking down accumulated soot, ash and other particulates that restrict airflow and harm engine performance.

Application is straightforward though it does require professional skills. You'll need to dismount the DPF from the vehicle before applying the pre-mixed solution directly to the filter. The cleaner then needs about two hours to soak through and work its magic, dissolving contaminants that would otherwise require costly filter replacement.

We appreciate that Wynn's formulated this product with environmental responsibility in mind. The biodegradable composition won't damage catalytic elements within the filter, maintaining emissions system integrity while thoroughly cleaning. For workshops dealing with severely blocked DPFs, this 5L container provides an effective alternative to replacing expensive filters, restoring proper pressure levels and improving overall engine efficiency.

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

Look for products that help reduce emissions while cleaning your DPF. The best cleaners will improve fuel economy and reduce your carbon footprint.

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.

Best Petrol Cleaners for 2025 UK

Best Petrol Cleaners

Keep your engine running smoothly with our top-rated petrol cleaning solutions

Petrol cleaners help keep engines running smoothly by removing grime, carbon deposits, and build-up from fuel systems. Over time, these deposits can lower your car’s performance, increase fuel use, and even cause engine problems. Regularly using a good petrol cleaner can prevent these issues and help extend the life of your vehicle.

There are many types of petrol cleaners available, from single-use bottles to additives used over time. Some cleaners work better with certain engine types or ages, while others target specific problems like moisture or injector build-up. It’s important to match the cleaner to your car’s needs for the best results.

When choosing a petrol cleaner, we look at how effective it is at cleaning, if it is safe for your engine and the environment, and if it’s easy to use. We also check the brand’s track record and whether the product meets car manufacturer standards. Our guide will help you find the best petrol cleaner to keep your engine running its best.

Best Petrol Cleaners

We’ve reviewed the top petrol cleaners to help you find the most effective options for your car. Our list includes trusted brands that deliver reliable results and help keep your engine running smoothly.

Oilsyn Petrol Doctor & DNA Kit

This is a solid choice for anyone who wants a thorough cleaning for their petrol engine without cutting corners on quality.

Pros

Cleans the full fuel system, from tank to turbo
Multiple detergent technologies with high strength PEA
E5 and E10 compatible and includes follow up cleaning treatment

Cons

Each bottle must be used separately
Not suitable for 2-stroke engines running premix
May be more costly than simple fuel additives

Instructions are simple but important to follow: Petrol Dr is used in the first tank and then Petrol Power DNA is used in subsequents tanks (1m per litre) to keep the system clean and protected. For those who want to keep both older and newer engines running their best, this makes Oilsyn a flexible and dependable pick.

We appreciate that using this kit can support lower maintenance costs and better fuel economy over time. While the initial price might be higher than basic additives, the benefits for engine care and emissions make it worthwhile. The 250ml Petrol Power DNA will treat a further 250L of fuel, approximately 4-5 tanks. Keeping our vehicles running cleaner and smoother feels straightforward with an option like this.

Check Price

Techron PEA Petrol System Cleaner

This option is worth considering if we want a fairly well-known cleaner that aims to target fuel system build-up in petrol engines.

Pros

Works with several petrol engine types, including hybrids
Helps remove deposits from injectors, valves, and combustion chambers
Can be used with ethanol blends like E10 and E85

Cons

Improvements may only last until the next refill
Some users see little effect with older or stubborn problems

It is formulated to protect components in petrol mixed with ethanol, which is common at UK pumps. This makes it a flexible choice when we are using E10 or E85. The product is easy to use as an add-in at the time of refuelling.

While some people find their engine runs more smoothly or idles better after using this cleaner, others report only short-term improvement or little visible change. However, this can occur if there are little to no deposits to remove. For routine maintenance or a regular clean, Techron is a good choice.

Check Price

STP Ultra Petrol Cleaner

This is a practical choice for anyone wanting an easy-to-use cleaner for petrol engines.

Pros

Works through the whole fuel system
Can help reduce engine wear
Promotes better fuel economy

Cons

Packaging may occasionally change
May not give big improvements for all cars
Needs a funnel for capless tanks

Some might notice the engine runs a bit smoother and with less hesitation. Others may not see big changes, especially if their car is already running well. As with many petrol system cleaners, the results will depend on the age and condition of your vehicle.

Although it’s an effective option on the market, other brands may offer higher strength cleaning. Still, the STP Ultra Petrol Cleaner provides a solid starting point for basic engine care at an affordable price.

Check Price

Archoil AR6400-P MAX Petrol Cleaner

This is a smart pick for those wanting an effective petrol cleaner trusted by professionals.

Pros

Cleans a wide range of engine parts in petrol vehicles
Helps improve engine smoothness and efficiency
Fast-acting, with results noticed shortly after use

Cons

May show subtle results in newer cars
Needs a full tank for proper use
Cost per treatment higher than some other brands

We like that this cleaner is not only for solving problems but also for preventing them, making it a good choice for regular upkeep as well as one-off fixes. Improved fuel economy is another reported benefit, but not guaranteed. There must first be a reduction of fuel economy before a cleaner can restore it. Backed by a performance guarantee and professional support, users can feel more confident adding it to their maintenance routine.

A few things to consider: some drivers may not notice dramatic changes, especially with newer cars. Its best effects are often seen in engines with more mileage or where performance has started to drop. Being a concentrate, it is important to use with the right amount of fuel for the results to show. For anyone looking to clean and protect a petrol engine, we find this product to be a reliable choice.

Wynn’s Xtreme Petrol System Cleaner

This is a solid choice if we want a straightforward petrol system cleaner for overall engine maintenance.

Pros

Removes stubborn carbon and residue, helping keep the fuel system healthy
Aims to restore fuel efficiency and improve throttle response
Proven formula offers strong cleaning compared to basic additives

Cons

Some users may not notice immediate results
Effectiveness may vary on heavy build-up or older engines

We note that its PEA formula is a plus, since this chemical is rated higher than older, less effective cleaners. The product’s reputation rests on keeping fuel injectors and key engine parts cleaner over time. That could lead to fewer cold starts, less rough idling, and potentially lower repair bills.

However, we’ve seen multiple reports that results are not always instant, and some vehicle owners may not see dramatic changes with just one use. While Wynn’s is a recognised name, more premium brands are often preferred by those wanting best-in-class detergent power. Still, for general petrol cleaning, this is a reliable choice without major drawbacks.

Check Price

Cataclean Petrol Fuel & Exhaust Cleaner

Cataclean could be a useful option for drivers who want a simple way to tackle carbon build-up, but it may not outperform specialists like Archoil or Oilsyn.

Pros

Cleans several parts of the fuel and exhaust system
May help lower emissions and improve fuel economy
Works with many petrol engines

Cons

Might not fix more serious engine issues
Results can be minor on newer vehicles
Regular use adds ongoing cost

Many users note improved fuel economy or a noticeable drop in emissions after using Cataclean, especially when following the instructions for regular use. It’s also quick to add, requiring little time or effort on our part.

However, for more serious engine problems or heavy carbon build-up, Cataclean might not be strong enough. In these cases, more expensive formulations could be more effective. For routine maintenance and keeping emissions in check, Cataclean offers a convenient solution that many drivers find helpful.

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. Engines with significant deposits typically show more noticeable improvements than well-maintained newer engines.

Are expensive petrol cleaners worth the extra cost?

Premium cleaners typically contain higher concentrations of active ingredients like PEA, which can provide better cleaning performance than budget alternatives. For engines with significant deposits or performance issues, the extra cost is often justified by better results and longer-lasting benefits.
