Isuzu recommends 5w-30 for most enviroments. If i remember correctly, diesel engine oil is much thicker (10w-40, 20w-50).

James, I ran a full synthetic in my MUA for a while. I switched to it hoping it would help calm the driveline noise i now get at 65mph, but in reality, i didn't notice any difference except in the check book. I'd say just go with normal dyno oil here.
