Back in the day when I owned my Cherokee 140 I used the Aero Shell 15w-50 oil. I have heard there is better stuff out there now? 'Elite' or others? Does it come down to the quality of care & how the engine is treated over oil differences? Every 25 hours or once a year" or more often? Any new favorites? How about a Filter besides the Champion? Lycoming 0320, thanks.
