Diesel and gas trucks don't just drive differently - they need completely different maintenance.
Your diesel has no spark plugs, no ignition coils, and no traditional catalytic converter. But it does have a Diesel Particulate Filter, an EGR system, and Diesel Exhaust Fluid that all need regular attention. Let one of them go and your truck goes into limp mode.
Your gas truck has its own list - spark plugs, ignition coils, O2 sensors, and a catalytic converter that fails fast when something upstream isn't right.
Both trucks share 10 critical services. Neither schedule is optional.
We built an interactive guide on our site that breaks it all down - every service item, every interval, with a filter so you can focus on your engine type.
