Jay GPS **Q: Can i get 15w-30 instread of 10w-30 oil?** A: We do not carry a 15w-30 oil. However, we do offer a kit without the oil just for those that prefer their own brand or weight of oil. https://www.amazon.com/dp/B07884TLCK?ref=myi_title_dp **Q: will this fit the fleetwood flair 29m onan 4000 ?** A: On the generator data tag is a field stating SPEC. If that is P-R, then, yes. **Q: Why is there no oil filter in kit?** A: This generator (the KY 4000) has no oil filter on it. It is a splash lubrication system, no oil pump to move oil through a filter; similar to a push lawnmower engine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Added value from a great small business! *by B***. on March 25, 2025* I was very pleased with this item.
