Thanks Chad, I'm using the Lawnbow ashless which was recommended by a friend. It seems to work great for the break-in but it's not synthetic. I have heard guys using Amasol but I don't know which kind and some of the guys also using the Penzoil synthetic. I will probably use the Klotz next flying season, I would just like to get something that will get me thru the rest of this season that is a good oil. I do not want to compromise my engine by using a cheap oil just to get in some flying. Thanks for the help! John
