Castrol GTX High Mileage 5W-20 Synthetic Blend Motor Oil, 5 Quarts

Castrol GTX High Mileage Motor Oil is the #1 high mileage brand and remains a trusted choice among drivers with high-mileage vehicles. It combines the benefits of a synthetic blend engine oil, providing ultimate engine protection against sludge, wear, burn-off, and safeguards your emission system.

However, Castrol GTX High Mileage Motor Oil features an advanced Phosphorous Replacement Technology, which replaces some of the phosphorous with a cutting-edge additive that ensures robust wear protection while preserving the health of your catalytic converter.
