Mobil Delvac — Protect your truck and equipment the right way

For more than 80 years, Mobil Delvac has been helping people who rely on their trucks extend the life of their vehicles’ engines. Year after year, decade after decade, they continue to put their trust in Mobil Delvac.
Why? Our commitment to be at the forefront of lubrication technology. Our dedication to research and development helps keep our products at the pinnacle of performance — which helps you keep your vehicle and equipment operating at their peak.
In the laboratory, we test Mobil Delvac in engines from all major manufacturers. On the road, we test Mobil Delvac by logging millions of miles in test fleets all around the country. That’s why every day, at truck stops nationwide, professional long-haul truckers select Mobil Delvac more than any other oil. And why the world’s five largest heavy-duty equipment manufacturers choose Mobil Delvac technology.
Mobil Delvac is the #1 brand of heavy duty diesel engine oil at truck stops.
To read more about why Mobil Delvac is the choice of so many Owner Operators, landscapers, agriculture professionals, contractors, and fleets, take a look at what they have to say in their own words.
With its unique formulation, Mobil Delvac can help deliver performance beyond the boundaries of conventional oils because its composition includes Trimer Core chemistry, a powerful additive technology that resists oil degradation, reduces sludge buildup, and prevents wear — ultimately extending drain intervals and engine life.
Mobil Delvac heavy-duty engine oils deliver long engine-life, help minimize engine wear, and reduce deposit formation — all of the key benefits you want from your oil. Mobil Delvac also offers a complete line of fully synthetic drivetrain fluids and high-performance greases that provide long equipment life and help you maximize the performance of your heavy-duty vehicle.
