SUPERIOR SLUDGE PROTECTION TO HELP EXTEND ENGINE LIFE! It's more than just oil. It's liquid engineering that protects against problems, like sludge, that 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.



Castrol GTX's double action formula cleans away old sludge and protects against new sludge formation better than tough industry standards demand.
