CASTROL GTX

CASTROL GTX: Superior sludge protection to help extend engine life

Severe driving conditions such as heavy traffic, harsh weather conditions and exceeding motor oil change intervals can all cause the build-up of a thick, tar-like substance called engine sludge. If untreated, it can rob an engine of power and, ultimately, its life.

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

Keep your engine clean and help extend engine life by choosing the right oil from the Castrol GTX range for your next engine oil change.

Our new Castrol GTX Ultraclean is the cleanest GTX ever. It helps extend engine life, giving you more control over today's challenging conditions.

CASTROL GTX
ULTRACLEAN
10W-40 A3/B4

Cars today have a tough life, and that's not going to change as they get older – it may even get worse. Heavy loads, towing, extended motorway trips, and long periods of idling while waiting for the family – all these are tough driving conditions. 

They can lead to high engine temperatures, and to elevated levels of contaminants from burnt and unburnt fuel accumulating in the oil. These can all result in engine sludge, which can shorten the engine's life.

Castrol GTX Ultraclean's synthetic technology has outstanding performance. Its Double Action formula cleans away old sludge, and protects against new sludge formation, giving you more control over today's challenging conditions.
