Castrol® GTX® 10W-40 is a premium conventional motor oil formulated to help extend engine life and protect against everyday wear. Trusted by drivers for over 50 years, Castrol GTX 10W-40 is engineered to fight harmful engine sludge and deliver reliable protection in tough driving conditions.
Sludge is a thick, tar-like build-up that can form when engines face severe use; stop-and-go traffic, poor fuel quality, harsh temperatures, or extended oil change intervals. Over time, this sludge can block vital oilways like cholesterol in arteries, reducing power and cutting engine life short. Castrol GTX 10W-40 helps keep those critical passages clean while protecting your engine from breakdown and deposits.
