Just wondering what oil most of you use on the Onan Microquiet. Mine is a 2014.It says any 30 wt. would be ok but would like to be a little more specific. Thanks for all the help

Probably every answer given in this thread so far would give great protection if the oil was changed regularly. Maybe we could narrow it down a bit more if you give a good idea how you would use the generator. Example grinding away on 100 degree day running the AC for hours. Or cooking a few minutes on microwave once in a while. Or winter camping battery charging.

I use Mobil 1 0W40 in mine. It will shear to heavy 30 weight, pretty much in spec w/ Onan. Good for all conditions. If I were doing lot of hot weather AC hours I really like the suggestion of the High Mileage 10W40.
