Is this for gasoline engines?

This is for Onan gas generators

Can i use this in a wood chipper with a 4 cycle engine?

If your wood chipper requires 15w 40 weight oil this would most likely meet the motors requirements.

It will work for 2022 Ram 2500 diesel?

Yes. It makes any diesel fuel become premium diesel. The 2022 Cummins may not NEED it as much as an older high mileage diesel, but will still get benefit from it
