Great

Good deals

Never been a better engine oil for your diesel. 392,000 miles and still running strong.

I spend almost twice as much on this at other stores. I will be getting it from here from now on and they had it ready for me the next day after I ordered .

Best oil out there for semi diesel trucks. Husband have been in the owner-operator business for decades. Best price he's have ever seen. Unbelievable, wish I could have purchased more than 5 cases. Delivery was prompt. Thanks Sam's Club!!!

I've been using this oil for 100K+ miles and have had no issues. I change my oil at 5-6K intervals and also keep an eye on the Sam's Club instant savings at which time I stock up.

I have never had any trouble out of this oil. My motor looks new inside and out. No build up at all. Pulled valve cover to change an injector and it is as clean as the day the heads were installed.

Great product. We have used this brand for many years in our businesses. It is dependable and consistent, always being our first choice, to keep our businesses moving foward.

I have looked all over online and Sams was the best deal for 6 count 1 gallon oil jugs. Very pleased! Will order again for sure. I use the oil for my commercial diesel lawnmower.

I’ve been using Rotella oil in all of my trucks for over 15 years. I’ve always had longevity with my diesel engines so, I continue to use what works for me.
