Oil Level

Hi - For those of you w/ the O-320 what do you keep your oil levels at? Just purchased a '71 140 and the previous owner said that he kept the oil at 6 qt. If he filled to 7 it would tend to blow it out. My last a/c had a O-235 and I kept the oil a qt low at 5. Seemed to work out ok.

What say you? Thanks
