That's why I just run NAPA 15W40, we have fuel trucks that have gone anywhere from 20,000 to 45,000 hours and still running strong on the stuff so I trust it. These trucks mainly idle about 18-20 hours a day and never really get up to and stay at operating temp, with the exception of when they're fueling aircraft. So they're basically used in the absolute worst way to run a diesel, but they just keep going. (We have 3 with DT466E, 1 DT466, 1 6B5.9T Cummins and 1 8.3l Cummins with a head bolt that's been broken off for at least 4 years LOL.
ETA yeah, just suck some out of the dipstick tube and send it in. Just make sure to pull it from at least a couple inches off the pan to avoid getting sludge in the sample.
Check my lists of common part numbers in my photos! Updated often!
1991 F350 Lariat XLT, 7.3l, 5-speed, crew cab, SRW, 3.55, 2WD.
1990 Jeep Wrangler Sahara, in the process of a major overhaul/upgrade. OM617 on the horizon! Front & rear Dana 44s from a Wagoneer till I get some 1-ton axles built & narrowed, and eventually a front shackle reversal. Diesel YJ, bay-BEE, and not a cookie-cutter 4BT conversion!
