My engine has used Phillips XC 20W50 since overhaul 900 hrs
ago. I had run it year round. However, with the extremely hot
weather we've had recently, and the engine getting a little older, I did switch
to straight 50 weight Aeroshell 100W for the summer. I'll go back to the
Phillips in the fall. Our A&P does not recommend the 100 Plus
though. Phillips get great reviews by those that use it.
However, some folks don't think a multigrade is right for the small
engines. I don't think you're going to be wrong either way.
