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.

Helps maintain engine performance and longevity.

Made with good consistency and great material.

Works well with both low and high mileage cars.

good fast service.  love working with  Walmart.

great

walmart.com

this oil has always done wonderful for my vehicles.

Walmart auto prices are cheaper than that of an Auto Parts Store.

Best low prices

I use this to keep fresh oil in my truck before I go to a oil change my truck is a 2002 so I love and need my truck so I take care of it I may not be able to purchase another truck like this one my favorite

I would buy this again

castrol.com

This is good oil if you are going to do your own oil change. I have used it for years and found that if it changed at 5,000 mile intervals, the engine internals stay clean and do not develop sludge.

Good Motor Oil for the DYI-er

I use this in older lawn mowers where full synthetic might not have enough base level viscosity to prevent leaks. Full synthetic is the way to go with current technology engines but best to go with the blend oil for anything with over 5 years on it.

Solid choice for best of both oils.

My vehicle has high mileage and this is the brand I always use. It has good consistency and it is a high quality product. I travel a lot and this products is always easy to find wherever I may be .

My Go To

Use this in my vehicle and have had no issues. Quality product and good price. It can be hard to find so I try to stock up when it is in stock. Used this product for years with no issues. Will never use any other brand

I have been exclusively using Castrol oil in my vehicles for over ten years. My Yukon has 315,000 miles on it. Castrol is a tremendous oil for my vehicle.

Does what it is supposed to do.

I've used this and this only 6 years now, it has always been great for My car and always recommend it to people. Will not use anything else as long as I can help it.

I would buy again.
