Good Deal on Generac Generator?
Neighbor has a nearly new Generac XP8000E generator for sale. He has installed a larger residential unit. Bought from Lowes for $1300 about a year ago. He's asking $800. It only has 10 hours on it but has been operated with regular 10W-30 motor oil. Generac says to use 5W-30 Full Synthetic. I'm wondering if there might be any premature damage to the engine by using the wrong oil. Would appreciate any comments. Thanks.
