If you mean engine oil, the answer is yes.

If you mean diesel fuel in a gas generator, the answer is no.
If you are talking about the engine oil, it's always better to use the specific oil recommended by the manufacturer.


What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

I have run Rotella 15-40 (T4) in everything from my lawn mower to a 15 liter diesel without any issues. Usually diesel motor oil will have more detergent in it then oils that are recommended for gas engines.

My ONAN is a diesel Kobata, it takes the same oil as my Cummins.

Yes in the recommended multi-viscosity for all the temperatures you plan to cold start it in or high temperatures you will run it at high loads.

The viscosity for temperatures will be shown in your manual.

Engines experience a high % of their wear from cold start to close to operating temperature - lubrication is critical on cold start.

Diesel oil has additives specific to diesel engines including specific to the catalytic converter used on automotive diesels. Rotella now makes oils for gas engines with different additives.

Check the oil spec for the generator...as long as you choose an oil of equal or higher standard, you will be fine.

Diesel oil is typically holds a higher end spec and will cause no problem in a generator. The other way around usually doesn't work.
