Castrol GTX is one of the world’s most trusted engine oils. It’s more than just oil. It’s liquid engineering that protects against the problems your engine faces every day. Severe driving conditions can cause the build-up of a thick, tar-like substance called sludge. Sludge can block your engine’s vital oilways like cholesterol – and if untreated, it can rob an engine of power, and ultimately, its life.
- Superior protection against engine sludge as measured in the Sequence VG sludge test
- Advanced protection against viscosity and thermal breakdown
- Premium quality base oils and anti-wear additives to help extend the life of your engine
