I like the bulk buy saves money

Good Quality

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

Great oil for diesel engines.I have been using Rotella oil in my tractors for 40 years and have never had any problem. Great price on quality oil and great service too.

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 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 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.

Absolutely the best price. This package would have cost us 2x as much where we are from. Of course we dont mind the long drive to get amazing deals, shopping here!

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.
