In this video I walk you through a step-by-step oil change and basic maintenance on a DuroMax generator, using the XP13000EH as the example. I cover the oil change schedule (including that important first oil change after break-in), then I show the regular oil change process: draining the old oil cleanly, refilling with the right oil, and how I think about capacity so you don’t underfill or overfill. The goal here is simple—keep the generator running smooth and avoid the easy mistakes that shorten engine life. After the oil, I move into quick checks that matter more than people think: inspecting/cleaning the air filter and checking the spark plug (including replacement and gapping). I also share practical dual-fuel tips—propane vs gasoline—and what I do differently depending on how the generator is being used. Finally, I go over long-term storage best practices (so it actually starts when you need it), plus a quick note on the battery location and replacement. No fluff—just the routine maintenance I’d do to keep a DuroMax ready for home backup power.
