@heavy_haul_n_fool: Just a quick little test to check for fuel dilution in the oil—nothing fancy, just a paper towel and some curiosity. Dropped some diesel oil on the paper to see if that telltale clear ring would show up. Didn’t see any signs of fuel in the oil, so I’m calling it a win. Simple, quick, and kinda fun if you’re into this sort of thing. #DieselLife #OilCheck #FuelInOil #DieselMaintenance #TruckMaintenance #PaperTowelTest #DieselDiagnostics #WrenchLife #DIYMechanic #DieselTech #PreventativeMaintenance #OilTest #DieselTruck #TruckLife #HeavyDutyMaintenance
Not a Cummins guy at any means but there’s high chances it’s just a weak fuel pump. Especially tuned trucks on original pump will struggle to hold pressure under high load, may need a pump, or a regulator if they have one. Either way, a good shop will put a gauge on it and drive it and go from there

It’s on cardboard not paper towels
