I don't use automobile oil the ZDDP is way to low for air cooled applications especially for continuous RPMs the shear stability isn't very high with these oils I only use Briggs and Stratton 5w30 100% synthetic or Amsoil small engine oil 5w30 100% synthetic they are around 1300 ppm on ZDDP the oil your using is around 750 ppm and no where near 100% synthetic there's a certain percentage that needs to be to labeled full synthetic even Mobil 1 not 100% not even close for most brands, the bearing load is way to high for low ZDDP oils the reason they are low level nowadays is the emission system they can't have alot zinc and phosphorus true small engine oil is very similar to racing oil except they have more detergents for dirt these car oils are ok for short outages and exercise but begins to wear the cams out and the main bearings on the crank prematurely the bearing loads on these engines are extreme compared to a passenger car
Thank you so much for this! I think it's ridiculous to pay $350 a year for maintenance on this exact model standby generator I have. I love it!
