Great deal

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 .

$$$$

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!

Diesel Motor Oil

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.

Long Time User; No Issues

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.

Sale deals

Customer should be able to purchase as many as they desire and not held to a mini. Sale . We would have purchased more at the $10.50 per gallon. Shopped elsewhere after this

Great Farm oil

I have been using 15w-40 Shell Rotella in my two Chevrolet farm trucks, a 2018 5.3L and a 2020 6.6L as soon as the factory warranty expires. Both trucks start fine in -15 degree Wisconsin winters. The real value is in 90+ degree summers when hauling hay from the field and hauling a skid steer for loading and unloading the 1,000 lb bales. This oil is far superior to the 0w-20 OEM OIL. I change oil and filters every 3,000-5,000 miles. BTW, I also use it in my older farm tractors. Excellent Product

great product

I have used Rotella in our large trucks and farm tractors for many years. The product delivers on quality and price was great too.
