Castrol GTX Petrol Passenger Car Engine Oil

Castrol GTX is designed especially for today's automotive petrol engines. It's more than just oil. It's liquid engineering that protects against problems, like sludge that your engines face every day. 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. You can?t see this sludge build-up but it can damage your engine?s performance and cause premature engine failure.
