Why we recommend professional engine care products
Engine Flush
We use a professional engine flush designed to help remove sludge, varnish and carbon deposits before fresh engine oil is added.
Cleaning these deposits allows the new engine oil to start life in a cleaner engine, helping maintain lubrication and overall engine cleanliness.
Fuel Treatments
We use professional fuel system treatments to help clean injectors and fuel system components, restoring spray patterns and helping engines run more efficiently.
They can also reduce deposits which naturally build up over time in both petrol and diesel engines.
Preventative Maintenance
We don’t recommend service products to hide problems or replace necessary repairs. We recommend them because, when used correctly, they form part of a sensible preventative maintenance programme.
Why use a professional engine flush?
Even when serviced regularly, engines gradually build up deposits from combustion by-products and degraded engine oil.
An engine flush is carried out immediately before an oil change, helping suspend contaminants so they can be drained away with the old oil.
- Helps remove sludge and varnish deposits
- Allows fresh oil to remain cleaner for longer
- Supports effective lubrication
- Can help reduce contamination left after draining
- Suitable as part of routine servicing where appropriate
Benefits of professional fuel system treatments
Modern direct injection engines are more sensitive than ever to fuel quality and deposit build-up.
Using a professional-quality fuel treatment during routine servicing can help maintain injector cleanliness and combustion efficiency.
While fuel treatments are not a cure for mechanical faults, they form an excellent part of preventative maintenance when used appropriately.
Common benefits include
- Cleaner injectors
- Improved fuel atomisation
- Smoother engine running
- Reduced combustion deposits
- Helps maintain fuel economy
- Supports emissions system performance
- Suitable for petrol and diesel engines (using the correct Forte product)
Renault Specialists. Not Generalists.
As Renault specialists, we only recommend products and procedures that we genuinely believe add value to the long-term reliability of your vehicle.
That’s why we use professional workshop-grade engine care products rather than inexpensive retail additives. We only recommend them where we believe they provide genuine long-term benefit to your vehicle.
Quality servicing goes beyond changing the oil.
Our servicing philosophy is simple:
- Use quality parts.
- Follow correct Renault procedures.
- Invest in specialist equipment.
- Recommend preventative maintenance where it genuinely benefits the vehicle.
Where appropriate, we use professional workshop-grade engine care products from trusted manufacturers, including Forte, to support preventative maintenance and help maintain long-term engine performance.
