Protection for Today’s Engine Designs

Engines are evolving dramatically as heavy duty engine manufacturers recommend thinner, lighter oils that increase fuel economy, reduce fuel costs and decrease greenhouse gas emissions. Plus, engine operating temperatures are increasing, which can demand more from engine oil.

The good news is one brand of heavy duty diesel engine oil, MAG 1®, has evolved right along with today's engines. Only the most advanced engine oils meet the difficult challenges of effectively balancing durability, extending drain intervals and protecting emissions control devices.
