great value for the price only thing if it gets overheated it gets dark fast! so watch the temperature

I use this oil in about 4 diesel engines and have not had any problems. And a lot cheaper then the other oils.

Great price for a Mobil oil for Diesel motors. I always try to buy this when it is on sale since my CAT C7 motor requires 25 quarts.

The product itself is good, the packaging was horrible. A very flimsy box and barely enough tape to keep it together.

the online system,inventory control, incorrect information and poor functionality was designed by amatures.

Use this oil in my boat’s diesel engines. Meets Volvo’s specs and with the Black Friday discount was a GREAT buy.

[This review was collected as part of a promotion.] Its the Beat product for my truck and you can't beat the price..

The case of oil came in a timely manner with no issues, busted case or damaged bottle's. Very happy.

I have used this oil for many years and I have never had problems with my engine internally and it has passed a million miles.

Great Strong packaging. Great plastic container with oil recommended for my 2021 Duramax 6.6L Diesel GMC 3500.
