Castrol GTX 15W-40 Engine Oil 1L - 3437477

(1,198 reviews)

Vehicles are staying on the roads longer and that means that they need experts to keep them moving, experts who put their trust in the right engine oil. Designed to fight engine sludge, a think tar-like substance that blocks oilways and affects performance. Castrol GTX's 3X clean formula works to CATCH, CONTROL and CLEAN engine sludge, not only neutralising old deposits but also creating a barrier that prevents new ones forming. This superior cleaning is vital because engine sludge just doesn't affect some cars, eventually it affects all of them. Help extend the life of your engine with Castrol GTX.
