CASTROL GTX ULTRACLEAN 15W-40 best
Castrol GTX ULTRACLEAN synthetic engine oil technology has superior performance. Its unique Double Action formula cleans away old sludge, and protects against new sludge formation, giving you more control over today´s challenging conditions. Castrol GTX ULTRACLEAN 15W-40 is suitable for use in automotive petrol and diesel engines where the manufacturer recommends an ACEA A3/B3, API SN/CF or earlier specification 15W-40 lubricant.

CASTROL GTX HIGH MILEAGE 15W-50 better
Castrol GTX High Mileage 15W-50 provides extra protection for engines with over 100,000 kilometres. 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-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. As an engine gets older gaskets become brittle, seals deteriorate and oil burns faster. Castrol GTX High Mileage helps extend engine life by providing superior protection against deposit build-up.* *vs. API SN/CF Industry Standards.
