Castrol GTX 15W-40 A3/B3 Car Engine Oil

Castrol bottles are changing! You may receive new style or old style bottles during the changeover, or a mix of both.

Castrol GTX is one of the world's most trusted motor oils. 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 such as every day stop-and-go/stop-start traffic, harsh weather conditions and extended drain 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. Protect your car from harmful sludge build-up with Castrol GTX.

GTX 15W-40 A3/B3 is a high-quality engine oil featuring anti-sludge properties. Castrol GTX's Double Action technology frees the engine from old deposits while providing better protection from black sludge.
