Oil for generator
I'm feeling kinda stupid. I cannot find my owner's manual and can't remember what weight of oil to use in the generator. Would appreciate any advice. It's an Onan 5500. Thanks in advance.

- I use Rotella T 15/40
- Go pull the cover. There might be a sticker on the air clearner with all types of fun info.
I remember searching around like crazy for the oil filter part number. Dang thing was printing on a sticker right in front of my face.
I also run Delo...15/40...because i alwasys have some leftover from an oil change in my truck. Plus its a good oil. Fella above runs it too i think. Minus the W. - I run Delow 40 weight
