Yes, DPF cleaners can damage your engine and DPF if used incorrectly, such as using the wrong type, overdosing, or applying them improperly, as they can create excessive heat, melt the filter core, harm sensors, damage injectors, or even lead to turbo failure and fires, necessitating correct product choice, strict adherence to dosing instructions, and addressing the root cause of the blockage.
Different DPF cleaners have different qualities. While some are made for heavy-duty trucks, others are made for passenger cars. Using the incorrect cleaner can cause damage to your engine and decrease its effectiveness. Make sure the product is compatible with the type of vehicle you own by always reading the label.
Deleting your diesel particulate filter is not a solution—it can lead to legal consequences, higher maintenance costs, and reduced engine efficiency. Instead, follow proper DPF cleaning procedures to: Ensure compliance with emissions laws. Extend filter lifespan and prevent costly replacements.
More seriously, the DPF's exterior might dissolve, causing red-hot particles to fall out, causing a vehicle fire.
A Diesel Particulate Filter (DPF) is an important part of a vehicle's exhaust system, designed to reduce the amount of soot and other particles emitted from the engine. Over time, the DPF can become clogged with these particles, which can cause engine performance issues and even damage the filter itself.
Maintaining a clean DPF can extend engine life by reducing needless pressure on engine components. Regular cleaning reduces wear and tear, resulting in a longer engine lifespan and lower maintenance expenses.
Simple and easy to use, you can add it to your car's fuel tank in a matter of seconds to clear soot and blockages from the DPF system. Like all Redex fuel additives, our DPF Cleaner can be added to a full or partially full fuel tank as and when required.
9 Worst Things You Can Do to a Diesel Engine
DPFs are designed to remove this soot as you drive, but over time they can stop working. To avoid expensive repair bills – especially as the cost of living increases - and to keep your car running smoothly, we recommend regular DPF cleaning.
Are there any downsides to doing a DPF delete? Increased risk of engine damage: Without the DPF filter, diesel engines can accumulate soot and particulates on engine components, leading to excessive wear and potential engine problems. This can result in higher maintenance costs and expensive repairs.
If your car has an automatic gearbox, change gears in manual mode, increasing the number of revolutions. However, there's no need to go as far as the rev limiter, as that won't do any good. Drive in this mode for at least 30 minutes. This will trigger a regeneration cycle and your DPF will be cleaned.
If your filter is found to be completely blocked, our technicians will inspect the car to understand what has caused the blockage and will carry out an intensive clean to solve the issue. In tough cases, the filter will be removed and soaked overnight before refitting.
Better Engine Performance and Fuel Economy
Regular DPF cleaning makes and keeps your engine drive smoothly. In fact, unless the filter is working at 100 percent your engine performance suffers. When you keep your filter clean, you'll get better fuel economy.
All they've ever wanted is big power, reliability, and mechanical simplicity. The Cummins 12-valve engine, and specifically the 5.9L 6BT, is all that and more. If you're just getting into diesel engines, calling the Cummins 12-valve engine the "Holy Grail" of diesel engines may seem like you are trapped in nostalgia.
Once you've added the DPF cleaner to your tank, it's usually recommended that you drive for at least another 15 minutes, preferably on a road with a fairly high speed limit. This will give the cleaner time to get to work on your blocked DPF, burning off any excess soot.
Use a DPF Chemical Cleaner
There are two types of chemical cleaners you will come across in the market – fuel additives and spray-on systems. Fuel additives are ideal for keeping a filter unclogged from the inside during use and can typically be poured into the filter without removal.
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute. Doing this increases the heat of the exhaust and burns the soot blocking the DPF filter. It's best to drive on a motorway or A road where you can keep the vehicle at a consistent speed.
Drive on motorways frequently—Motorway driving allows your car to complete DPF regeneration. Use the right fuel and oil—helps reduce excess soot build-up. Don't ignore warning lights—address issues early to avoid expensive repairs. Avoid short trips—they increase accumulated soot without allowing regeneration.
