Castrol GTX 20w-50 Motor Oil is re-engineered with TriShield technology to actively protect against deposit build-up. TriShield attracts, captures and disperses small deposit particles before they become big problems. Engine deposits can turn into a thick, dark substance that can wreak havoc within an engine, building up and clogging oil passages. Deposit build-up can lead to reduced gas mileage, decreased engine performance, and in some cases, engine seizure. What's worse, once it builds up in an engine, it's almost impossible to remove.
- Unique TriShield chronology provides superior deposit protection
- Maximum protection against viscosity & thermal breakdown
- Premium, custom-made additives enable advanced performance
