As luck would have it, I am employed as a chemist and spend much of my time analyzing ignitable liquids. White gas and similar products are very similar to the more volatile parts of gasoline.

Mixing it with gasoline won't be a problem. Use it in your lawnmower, car, whatever. Running it straight would actually burn cleaner than gasoline, but if you have a couple of gallons of gas in your tank already it is unlikely you'll notice a difference.

It can be used in liquid fuel cigarette lighters, such as Zippos. Some brands of liquid camp stove fuel are chemically indistinguishable from Zippo lighter fuel.

If you plan on staying in a campground another option would be to spot someone using an old school camp stove and offer it to them. I suspect most camp stoves in campgrounds are propane these days though but you could always try.
