Product Information

Update – October 2023– We have updated our product recommendations in line with some excellent new products that have been released in the UK market. If your diesel car is fitted with a DPF, it’s imperative that you use DPF compliant engine oil. Using an oil that doesn’t meet the required specifications for your engine can result in catostrophic failure. After lots messing around with a new aftermarket DPF (Which turned out to be faulty!) and new DPF sensors I bought this product to clean out my original DPF. It's very easy to use by sealing off one end and leaving it for up to 8 hours.

If you have an automatic select the auto second gear position and drive the engine around 5,000 rpm.The Used Car Guy holds no liability for your outcomes when trying the procedure listed above. This article is meant only to aid car owners that wish to avoid spending large amounts of money on their used car. DPF’s have been fitted to comply with European emissions regulations and it is illegal to alter or remove the system.

Another contributing factor to DPF problems is poor quality diesel fuel. The more expensive, premium fuels contain additional additives which help reduce the amount of soot build up.

Generally, this occurs when driving on a motorway at speeds of around 50-70mph for more than 30 minutes. Put the numbers to one side and notice that hundreds of car repair garages continue to offer the removal of DPF filters. MP’s are labelling this practice as ‘detrimental to people’s health’ and ‘unacceptable’.If the DPF filter reaches a certain percentage full level, your car will give you a warning light which will look something similar to the image below (The image will vary between car manufacturer but will generally look very similar)
