As car engines get older, they begin to accumulate sludge made from burnt and unburnt fuel contaminants. This sludge can significantly affect the performance of both petrol and diesel engines unless you take steps to protect your vehicle.
The Castrol GTX range is designed for this purpose, with products that clear away old sludge and prevent new sludge formation thanks to their precision-engineered double-action formula. This leaves engines cleaner and ensures performance remains consistent throughout your engine’s life.
Every one of these trusted engine oils offers the highest levels of sludge protection compared to other products on the market, and exceeds the API SN industry standard in tests.
If your vehicle or fleet needs to operate under severe driving conditions - including carrying heavy loads and towing, regular long journeys, and frequent periods of idling - the Castrol GTX Ultraclean range is a must-have for you.
By using best practices and choosing engine oils that exceed tough industry standards, you can extend engine life, reduce maintenance requirements, and prevent harmful sludge from forming.
