Castrol GTX is one of the world’s most trusted engine oils. It protects against problems that your engine faces everyday.
Severe driving conditions such as heavy traffic, combustion contaminants, harsh weather conditions and exceeding oil change intervals can all cause the build-up of a thick, tar-like substance called sludge. If untreated, it can rob an engine of power and, ultimately, its life.
Castrol GTX with its Double Action formula, is formulated to extend the life of your engine by preventing the harmful build-up of sludge, reduce oil deposits and protect your engine.
