Castrol GTX High Mileage Synthetic Motor Oil 10W-30 5 Quart - HIMI10-30-5QT

Motor Oil; High Mileage; 10W-30; 5 Quart; Castrol GTX High Mileage motor oil is the leading consumer high-mileage brand. You won't need to worry about using a high mileage oil or synthetic because this is both. It's a synthetic blend engine oil that helps extend the life of your engine by protecting against sludge, wear, and burn-off and also liquid engineered to protect your emission system. One of the leading causes of 'check engine' lights coming on in high mileage cars is actually catalytic converter failure, which can be caused by phosphorous in engine oil. While phosphorous is present in all engine oils for its ability to reduce wear, it is effectively poisonous to catalytic converters. Castrol GTX High Mileage Motor Oil is liquid engineered with Phosphorous Replacement Technology to replace some of the phosphorous with an advanced additive that maintains robust wear protection. When you want to extend the life of your high mileage engine and emission system and find out how many miles you can go on a high-mileage oil, there is no better choice than Castrol GTX High Mileage Motor Oil.
