hello boys i too have bought one of these motors. i also run DA motors. as to the oil its really simple go to ace hardwear and buy lawnboy ashless to brake the motor in. this is the very same as with DA after 3 gallons then switch to a very good synth. oil as i myself am using belray racing oil which can be had at any yamaha place. this too is recomended by DA. so if iits good enough for DA then the DL will handle it. and as others have said do as the instructions say. dont just pick up a can of oil READ THE LABLE for contents. now dont everyone get all upset iam not trying to put anyone down. it just seems that way too many people have problems with this.[sm=teeth_smile.gif]
