Castrol GTX Professional is one of the world’s most trusted engine oils It’s more than just oil. It’s liquid engineering that protects against problems, like sludge that your engines faces every day. 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.

You can’t see this sludge build-up but it can damage your engine’s performance and cause premature engine failure.
