SAE 30 32 to 100+
15w-40 10 to 100+
10w30/40 0 to 100
5w-30 - -20 to 50
The latter numbers is the temp range... per the manual. I ran Rotella 10w30 last time around 50 hours with no issue's. I put Pennzoil Ultra 5w30 in it this time. If your using synthetic's probably any range will work but with dino juice I'd stick to the list above.
Just don't hit the start button filling it up!
