Heavy Duty Engine Oils
DURON-E and DURON

Minimizing engine wear is critical to reducing downtime and extending the life of your engine. Especially in today’s tough operating conditions that can produce and retain more soot than ever before. By controlling soot, DURON™ provides exceptional defense against engine wear.
