Castrol – GTX 10W-30 High Mileage Synthetic Blend Motor Oil: 5 Quart (Part No.1597B0)

GTX 10W-30 High Mileage Synthetic Blend Motor Oil: 5 Quart

from

$30.99
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.
