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.

No issues with this product and I've exclusively bought this brand for four years running. This is the only brand I buy and it's great for high mileage cars. Extends the life of your vehicle with regular oil changes.

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 !!

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).

This is my go to product for my Jeep. Always choose this brand and this blend. Never have any issues and will continue to run this in my Jeep. Haven't had any issues with it and the price point is good too.

Affordable fairly priced good oil. Better on an engine with higher miles on it. This is my go to oil whenever I do an oil change on any of my higher mileage vehicles. I would definitely recommend this.

I've used this brand since I've been driving and have always been satisfied with it's performance. My dad has also always used it and recommended it to me. It's not the lowest priced but it's less expensive than some other brands.

I use this oil in my car since I'm now over 200000 miles. It's not too expensive and my mechanic has no problem with it if I let don't change my oil within the recommended timeline.

This is a great oil to use on cars with high mileage. I have tried other brands of oil but have switch back because it doesn't work as well as Castro oil works. I would highly recommend this for older vehicles.

This is a great product and I always feel that my engine is very protected with this brand. Has been using for many years with a lot of different vehicles they have never let me down. Will never switch to anything else.
