Recomended oil for Onan 4KW generator
Hi We have an Onan model 4KYFA26100K 4 KW generator in our Class C and were wondering what is the recommended oil type for it? Thanks.

My Onan 4K recommends 30W or 10W30 but these things tend to run VERY hot so I use 10W40 synthetic.....which is the recommended oil weight for most air cooled motorcycles.
