Castrol GTX 10W-30 Conventional Motor Oil, Case of 6-1 Quart Bottles |

Castrol® GTX® 10W-30 is a premium conventional motor oil designed to help extend engine life and keep your vehicle running smoothly. For over 50 years, drivers have trusted Castrol GTX to protect their engines from harmful sludge and everyday wear.

Its advanced formula helps prevent the build-up of thick, tar-like sludge that can form under severe driving conditions, such as stop-and-go traffic, low-quality fuel, extreme temperatures, and extended oil change intervals. Left untreated, sludge can block vital engine oilways like cholesterol in arteries, reducing power and, over time, shortening your engine’s life.

Castrol GTX 10W-30 helps keep those critical passages clean while protecting against viscosity and thermal breakdown, so your engine gets reliable protection mile after mile.
