About Engine Flush & Fuel Treatments

An engine flush cleans the oil ways, sumps and components in an engine from old oil and deposits of contaminants. Surfactants are flushed through the engine to thin remaining deposits of oil in the system and break down thick sludge.

Excess material from the engine is then drained and removed from the engine, before detergent is flushed through the system to clean away left over residue. Finally, a series of solvents and detergents are flushed through the engine to clean the oil ways.

Fuel treatment is available for both petrol and diesel engines. Treatment for petrol engines removes resins and residues left over by the fuel and cleans fuel injectors, chambers and valves. For diesel cars, fuel treatment cleans away bacteria and slimy deposits that can create excessive engine noise and exhaust fumes. It will also unclog fuel filters clean away corrosive contaminants from engine parts.

  • What are the benefits of an engine flush?

    Synthetic oil is unable to absorb all dirt and particles. If these are left to build up inside your engine, they can start to clog oil ways. This can starve the engine of vital oil and lead to premature wear and failure, which can be extremely expensive to fix.

    An engine flush is a cost-effective and affordable way to remove these particles from your engine and prevent unnecessary wear and tear. It can be done quickly at any Stoneacre branch by our expert technicians.

    Driving has changed in recent years. With more cars on the road, you’re more likely to encounter slow moving congestion. Add that to the increased amount of city driving many of us now do and our engines are subject to more stop-start wear than ever before.

    This short trip, stop-start driving can result in a particles in the oil building up to cause deposits in the engine. If left untreated, these deposits can create gunk which can then restrict oil flow and cause damage.

    Although new synthetic oils claim to prevent a build-up of sludge, they’re not as soluble as old mineral oils and are less efficient at absorbing dirt and particles.

    An engine flush helps to resolve this problem by using chemicals to clean out these deposits and help fresh oil move around your engine freely.

  • What are the benefits of fuel treatment?

    The second stage of our comprehensive engine oil flush is an additional fuel treatment. This can be carried out on petrol and diesel engines to clean the entire fuel system.

    Our petrol fuel treatment involves removing resins and oxidation residues that build up over time. This reduces valve and chamber deposits and maintains the cleanliness of your fuel injectors. We also add an ‘Octane Boost’ to help deliver improved fuel consumption, which could save you money.

    A Stoneacre petrol fuel treatment has the added benefit of lowering your car’s Co2 emissions too, making it easier to pass the strict MOT emissions test.

    Our diesel engine flush and diesel fuel treatment also lowers Co2 emissions. This thorough fuel system cleaning reduces excessive smoke and engine noise too. Plus, by eliminating slime producing fungi and bacteria, a diesel fuel treatment prevents filters and pipelines from clogging and also avoids corrosion of metal and rubber parts.

  • How long does an engine flush take?

    An engine flush as a standalone treatment commonly takes around 45 minutes to complete. You can book a engine flush or fuel treatment together with your car service and have both done on the same day. An engine flush can be completed alongside a service and will not add to the duration of the service.
