Castrol 03095 GTX 20W-50 Motor Oil

Sludge can block your engine’s vital oilways like cholesterol and if untreated, can rob an engine of its power and ultimately its life.

Castrol GTX is a premium conventional motor oil that has been helping to extend engine life for over 50 years. It has evolved to meet the needs of consumers and vehicle manufacturers since 1968 and continues to innovate and remain a trusted brand today. Severe driving conditions such as heavy traffic, poor fuel quality, harsh driving conditions and exceeding oil change intervals can all cause the build-up of a thick, tar like substance called sludge.

If untreated, it can rob an engine of its power and ultimately its life. This oil is specially engineered to prevent the harmful build-up of sludge while protecting against new sludge formation better than tough industry standards.

    I’ve used regular Castro GTX for nearly 50 years and have never had a damaged engine. I’ve been trying to find a good reason to use synthetic for almost 35 of those years and haven’t found it yet! Why pay more for synthetic when it’s basically an equivalent product! Change your oil and filter every 3K-5K miles! Don’t fall for that 15K story told to you by companies whose business models rely on your to buy a new cars just after the old warranty runs out. They have no desire for your vehicle to last a long time, just the contrary! So why would you believe them about oil life?

    This is all I use for my 1983 Kawasaki KZ440 LTD. It has a wet clutch so you want little to no friction additives. I believe this has some additives but not nearly as many as the synthetic oils out there now. Can’t find this oil in any stores!!
