Castrol GTX High Mileage motor oil is the leading consumer high-mileage brand. It's a synthetic blend motor oil that helps extend the life of your engine by protecting against sludge, wear and burn-off. Castrol GTX High Mileage is also engineered to protect your emission system. One of the leading causes of 'check engine' lights coming on in high mileage cars is catalytic converter failure, which can be caused by phosphorous in engine oil.
