anyone see any problems with using M1 0w-30 AFE in a Subaru Robin powered generator? i can't find a recommendation from Homelite or Subaru. i bought it used a couple years ago when my son was born so i could run the furnace in the event of a sustained power outage in the winter. haven't ever needed it, but if i do, as sure as i type it will be colder than cold out when i need it. thinking the 0w would be great for cold starts, and robust enough to use all year long, if needed. plus with never being used, i figured i'd probably never have to change it with the M1 on board. haven't even started the thing in over a year, but i started it up today and by gosh it fired on the first pull thoughts on the 0w-30?
