my old jeep Cherokee had a table in the operators manual that listed several grades dependent on environment. I kept 20w50 in it as I found that it stayed inside a lot longer than 15w40 , to be fair if it didn't leak it wouldn't have been a Jeep. best thjing was running it on LPG as the oil was almost as clean coming back out on oil change time as it was going in . ( might be due to changing the oil through leakage )
