Castrol® GTX® 20W-50 is a premium conventional engine oil designed to help extend engine life and protect hardworking gasoline engines, especially older or high-mileage vehicles. Trusted for over 50 years, Castrol GTX 20W-50 is formulated to fight harmful sludge and deposits that can reduce engine performance over time.
Sludge is a thick, tar-like residue that can form when engines face severe driving conditions; stop-and-go traffic, poor fuel quality, extreme temperatures, and extended oil change intervals. This build-up can clog vital engine oilways like cholesterol in arteries, robbing your engine of power and shortening its life. Castrol GTX 20W-50 helps keep those critical passages clean while delivering strong protection against wear, heat, and breakdown.
