I feed this to my 1993 E-350 bus with the 7.3 IDI. The old girl loves it, and even helps on the cold starts. Cant beat the Sams price either....

I use Shell rotella T5 15W40 in all my diesel trucks and tractors great oil and a great price Sam's club is number One for oil.

We used to find this oil in your store but haven't been able to in a long time. We have farm tractors and it was so handy to just order this on line and have it shipped free to our door.

Five years ago I started using this oil from Sam’s. I had 26,000 Miles on my truck. I now have 620,000 miles and counting Rotella T-5 is great. Thanks Sam’s Club for having affordable prices

Great product

The go to oil for a Diesel engine also works great on a Subaru. Great quality and it can be shipped...no I dont work for Sams

Top quality oil for my Cummings Diesel engine, conveniently packaged in a three pack at the best price anywhere.
