Oil used for an Onan for a 2014 Sunseeker
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

Because I use the Microquiet 4000 in both cold and warm seasons, I use a name brand 15W40, diesel spec. Usually Delvac or Rotella, as I am in ExxonMobile and Shell marketing territory, but Delo would be the same if you are in Chevron country.
