Castrol GTX is one of the world's most trusted engine oils. Environmental factors such as poor fuel quality, hot weather and stop-start driving conditions can lead to sludge, varnish and carbon build-up in your engine: three factors that reduce engine life, power and fuel economy. Castrol GTX is a synthetic blend engine oil. Its double-action formula has been proven to clean away the sludge that can block engine oilways and helps prevent new sludge formation thanks to its synthetic technology. In fact, it provides up to 45 better sludge protection than is demanded by the latest industry standard. If keeping your engine clean is important to you, it's good to know that no other oil keeps engines cleaner.

Great at the price

We use this oil in all of our vehicles. We have missed an oil change in our jeep but never had a problem with the engine getting hot. The product definitely works great and is very affordable. We will always use this product.

Has never let us down!

Castrol

Bought this product for our scooter. Works well easy to use. Great for smaller engines and longevity for the engine. Buying name brand has worked well for us with regard to engines and other oil needs.

Great Product

Very good oil which I used in my riding lawnmower and push mower and been using this oil for many years! No problem with either engine and base stay clean and no major engine problems.

Very good convention oil!

My husband purchases this brand every time he does our oil changes and swears it one of the best! We have never had any issues and will definitely continue to buy it.

My husband prefers this oil to other brands

I like how it helps my car run way better than the cheaper versions. It helps it run smoother and cleaner. I can go further between changes with this oil. I recommend this brand of oil. It is worth the few extra dollars.

Works great.

Very good conventional, non-synthetic oil.
Critical for rotary engines.

Great non-synthetic oil.

I would say it is a very good product!...
