Premium gas in fuel station?


Still fairly new to this forum and also new to 5th wheeling, but not to RVing. We had a motor home for 15 years before buying our Raptor 3812.

Now as to the question: Will it cause any damage to put premium gas in the fuel station that also serves the generator? The motorcycles both require premium but the generator only needs regular. Obviously I won't use regular in my mc's but is there any harm, other than money, in using premium in the Onan generator? Any other reason I'm not thinking of for not doing this besides making sure gas in the tank and in the lines is kept fresh and the generator is started and run a couple times a month? Of course, the bikes can be driven to a gas station but as long as I've got a mobile gas station, why not use it?

Thanks for any input on this.

No problem at all. Won't "help" the generator, won't hurt it. Perfectly fine. For the amount of time you'll likely run the generator, it shouldn't really amount to much money either. Other option is to do what most toy haulers already do, and run two tanks. Not real common to have a single tank, but I guess some companies make the second tank optional.

I would say it won't hurt the genny, but it could make it harder to start, don't have any experience in reference to gennys, but I did have a 89 Pontiac GrandAm with the 2.5 Iron Duke 4 banger and tried mid-grade in it to see if I could get any better mileage over Reg, and it was harder to start. Would crank longer before starting. I would experiment with the genny first. Just my nickel's worth (inflation you know)
