This is the only brand we trust for our high mileage vehicles. We've had several vehicles make it well past 300000 miles ensuring we only used this product and used it at every 5000 miles. The best option at an affordable price.

This seems to be good quality and I noticed that it lasts longer. I drive a lot for work and found myself having to add oil in between changes. But with this it doesn't burn as quickly and seems to be high performance.

I use this in my grandfather's high mileage Kia that has to have a quart about every two weeks...I highly recommend this product I usually can catch it on sale at the Dollar general store for a 1 cheaper than other oils

Works great in keeping my husband's truck running smooth and steady. He drives a lot to and from work and it lasts a good while before needing changed.

Does the job without breaking the bank. We have to have 10 qts just to change the oil in the truck so it's nice when it doesn't cost $50+ just for the oil before we even count the filter and disposal (and that's with free labor).

Always my go to oil when I can afford it. I had a small oil leak and this brand would last longer but it usually cost more so I can't always get it although maybe I should have paid the extra so my van would have lasted longer.

Definitely recommend this brand. The price is just right it's not the cheap bad stuff but not expensive overpriced like others! My cars run great using this brand

My 2005 suburban has over 292000 miles on the engine - the only time I haven't used Castrol is when I couldn't find it ! I'm sure it has helped keep it alive and running !!

I've been using this product for over years in about 5 different vehicles that I've personally owned. It has worked very good and rates highest in it's class.

I use this in all my cars. Best oil made.. I've used this oil for years I won't put any other oil in my cars.. I've never had a problem with using this oil..I recommend this oil to everyone
