Superior product

Great product! I use it in my duramax at every oil change. Doesn't burn, engine consistently runs smooth. Price is very reasonable even for the larger quantities. Highly recommended to everyone running a diesel engine

Believer

I have used 1300 in all my vehicles right now both my vehicles have 8.1 V8 engines. One motor is new, (because I bought the truck with a bad motor) and the other motor is running strong at 300,000 miles!

Works well in my Ford SuperDuty

I have used Mobil products exclusively in my Ford Superduty. Lubrication is the cheapest way to protect your investment. They are the only name for my vehicles.

What my Dealer uses

I bought this because my dealer uses it and i wanted to use the same brand of oil . I wish it would be sold in Quart containers .

Delvac 1300

Great stuff for my Briggs and Stratton lawn mowers and my Royal Enfield Classic 500! They run perfectly on this stuff. Thanks Delvac!

One of the best engine oils out there

We use Mobile Delvac at home and work with many of our larger pieces of mobile equipment having over 20k hours on them. Without oil related issues.

Good Oil

Have been using it for many many years. Over 200K on my 35 year old class A motorhome with zero lubrication/engine issues
