Slow is smooth! And Smooth is FAST

I love this oil! I've used it in almost every vehicle I've owned when the mileage has been 90'000 and above! It keeps my vehicles running longer and smoother! Oil change intervals are not as soon, and seems to increase performance some! Again all of these oils are the same, even made by the same companies, just put different names on the labels! I highly recommend Castrol GTX, I go with what I've used and what I know, and I know this is one of the best! Buy it!

I ordered this great product via on-line, I appreciate the speedy shipping and the condition of my items I received. I give great credit to those involved. Castrol is a very fine product which I recommend to anyone. Our Walmart Supercenter here in Chandler Oklahoma is one of the best in my opinion. All of the staff has always been so kind and very helpful. Many Kudos to Justin who works at the service desk

Castrol GTX High Mileage 10W-30 Synthetic Blend Mo

I have a 1996 F-150 I drive daily and I use this motor oil in and have no issues with the performance of my truck. Great value for the 5 quart bottle makes oil changes easier I think. I just buy the extra quart needed and I am done with less bottles to clean up and throw away. Works great protecting those internal parts especially if you have a vehicle with high mileage which most look at when it reaches 100,000 mark.
