I currently use M1 Syn HM 10w30 in my 2007 Generac twin cyl gen that runs 3600 rpm in the heat of the deep south. This gen has only 200 hrs despite its age. Also I use non-ethanol gas in my small engines. The question is, would this gen derive any significant benefit from using Valvoline VR1 10w30 conventional racing oil over M1 SYN 10W30 given the sustained heat and high rpms. Any serious thoughts welcome.
