Passenger and light-duty vehicle manufacturers continue to evolve engine designs. Modern engines are getting smaller while producing more power. They now require thinner, lighter oils for increased fuel economy. Our advanced motor oils have evolved right alongside today’s engines to meet the difficult challenges of effectively balancing performance, strength, and durability.

Proven performance
- Our DOC Mag1 Full Synthetic and DOC Semi-Synthetic passenger car motor oils control friction and wear better than current API (American Petroleum Institute) requirements.
- They help maximize fuel mileage performance.
- Advanced molecules in the oil bond together to create a wear-resistant shield that works to keep rotating metal surfaces from coming into contact. Even under the most severe testing and operating conditions, over extended periods of time, engine wear is virtually undetectable by conventional methods.
- DOC oil provides unsurpassed performance, even in extreme hot and cold climates, stop-and-go traffic, hauling heavy loads, or operating in dusty environments.
Quality you can trust


All of our engine oils are certified by the American Petroleum Institute, the governing body for engine oils. They all meet or exceed the OEM specifications and some are actually certified by the OEMs directly.
