posifour11 723 #4 Posted May 10, 2019 I try to use Rotella straight 30. I'm by no means an expert. Just what I do. 2 1 Share this post Link to post Share on other sites
JAinVA 4,637 #5 Posted May 10, 2019 (edited) The brand is always the subject of debate.Single weight or multiweight is as well.One thing is not so much.Since these single cylinder aircooled engines have no oil filter, change the oil at 20 hour intervals.Hour meters are worth the trouble and expense to install.

Retired Wrencher 5,792 #8 Posted May 11, 2019 (edited) I look for the highest API rating and go from there. But make sure it is a detergent oil. Edited May 11, 2019 by Retierd Wrencher Share this post Link to post Share on other sites
