Reliable synthetic blend for high mileage vehicles. Castrol GTX High Mileage 20W-50 is our go-to oil for older vehicles and high-mileage units in our dealership inventory. The synthetic blend formula provides good protection for engines with significant wear. The 20W-50 viscosity helps reduce oil consumption in higher mileage engines. We've had excellent results using this in trucks and SUVs with over 100k miles. The seal conditioning additives help prevent leaks. Price point is reasonable for a quality synthetic blend. The 5-quart bottles are convenient for standard oil changes. Castrol quality and reputation you can trust. Solid choice for keeping high-mileage vehicles running strong.
