Diesel Diesel Service and Maintenance Intervals

Keep Your Rig Going

We've rigorously tested our engines to create solid routine Detroit Diesel maintenance intervals so you know what needs to be replaced when. And your engine's extended maintenance intervals also reduce downtime so you stay on the road longer. And when it is time for maintenance, our 800 service locations mean you're never far from better performance.
