Spinning Loading Wheel

Severe driving conditions such as heavy traffic, poor fuel quality, 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.

This oil is specially engineered to prevent the harmful build-up of sludge, reduce oil deposits and provide daily protection for your engine.

To get more kilometers from your engine ask for the right oil from the successful Castrol GTX range. Your best kilometers are ahead with Castrol GTX.
