N Nova RV Well Known Member Mar 14, 2022 #2 I have found that anything over 6 blows out quickly. At 5 or 5 1/2 it is very stable. 3yrs and 220 hrs on my IO-390

B Bavafa Well Known Member Mar 14, 2022 #3 On my IO390, I kept the oil at 7 and added when it was down to 6. I did not see much oil at the belly with this level.

Jetmart Well Known Member Mar 14, 2022 #4 I have found that most people recommend no higher than 6 quarts. I run between 4.5 & 6. I know van's runs between 4 & 6.

KeithB Well Known Member Mar 14, 2022 #5 300 hours since install, I load 7 quarts after an oil change (or before a long cross-country) and then add one quart when down to 5. I see no difference in consumption at any level.
