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

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.

[This review was collected as part of a promotion.] Mobil Delvac 1300, is an excellent product with a good reputation and excellent pricing.

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

I have used this oil in my 1997 Mack for 15 Years. I never Had any problems with this oil. It does a great job for sure.

Great oil at great price. Use it in the tractors and with lesser cost tend to change it out more frequently.

i use this in both of my 99 F250s with the 7.3l. four gallons fit like a glove. one engine has over 400,000 miles and still going strong.
