I posted this in this forum so that more people would see, because I'm sure a lot of you have thought about this too! I picked up my lawnmower from the maintenance place.. it was just easier since they have the air filter, they know what plug it uses, etc. So I checked the oil in it today and it was overfilled by a LOT! This gets me upset.. do they not even check?? So I took all that oil out, put it in an old Mobil1-0w40 bottle, and refilled it to the proper level with PP 5W30 and RTS 5W40 (it calls for SAE30) ..the oil I took out will be for toping-off. Anyone else here put synthetic in their lawnmowers?? Any complications?? Mine feels "stronger" so far but could just be me. That's when I checked it: PP 5W30 in! Old-new SAE30 lawnmower oil in the Mobil bottle, don't worry.. now I put a label on it so it won't get confused with my other Mobil-0w40s.
