So I have mentioned that Zippo/Ronson ligher fluid (not charcoal lighter fluid) was naptha and a good substitute for Coleman fuel (also naptha). It is widely available in many small sized bottles. It is kind of expensive, but I figured that $4 for 12 ounces wasn't terrible for a fuel that was readily available on the road in a size that suited my needs perfectly.

I finally got around to buying some and doing some test runs in my stoves. First off the 12 ounce bottle has a nice little dispenser spout that I'd be willing to carry in my bags and not worry much about spillage with some care in packing. It is slow for filling a stove, but precise so no spilling. It is easy to dispense just a little to prime a stove that needs primimg, but whether it gets to the priming cup would depend on the stove. I burned some in both the Whisperlite International and the SVEA 123 and it was indistinguishable from coleman fuel in the ease of starting and flame. I didn't do timed boil tests, I don't obsess of that, but it had a nice hot flame. It throtled down to a simmer to the same level as coleman fuel. Basically there was no difference that I could see. I think this will be my go to fuel when I need to fly to somewhere and buy fuel for a white gas stove on a solo trip. That is if I fly with a white gas stove. I am actually more likely to use alcohol or a canister stove if flying. I am disinclined to risk losing my SVEA or whisperlite to the TSA so It is more likely to be mailed ahead or used on tours that I drive to. Driving to a tour or backpacking trip with a white gas stove I'd start out with "real" coleman fuel (or maybe crown brand), but might need to restock mid trip so the zippo/ronson may come in at that point.

For me buying a gallon or even a quart of coleman fuel is just too much. I typically would use the 11 ounce MSR fuel bottle if I take the whisperlite, so even the 12 ounce bottle of zippo/ronson is more than optimum and I'd likely opt for one of the smaller sizes if available to avoid taking the remaining ounce in the 12 ounce bottle it came in (the empty bottle is probably an ounce or so).

The SVEA has about a 4 ounce capacity so I'd likely either buy a 4 ounce bottle or buy a bigger one and carry the zippo/ronson bottle the fuel came in with the remainder. Alternately I'd take the 11 ounce MSR bottle.

Edit:
By the way, The Whisperlite international will burn kerosene with a jet swap (jet is included with the stove). The thing is I know of no reliable source for kerosene in the very small quantities I'd want to buy on the road. Charcoal lighter is available in quarts and gallons. Kerosene is sometimes available from a pump like gasoline, but I don't thin it is very universally so. REI and Walmart both list Crown Fuel Kerosene 1-K Camp Fuel in a 1 quart size for $9.95 and $6.47 respectivelt here in Tallahassee. It is just a little cheaper than Crown white gas from the same sources and given the choice I'd rather burn white gas. In any case, for me the quart size is more than I want for an on the road fill up, so I am back to the Zippo/Ronson lighter fluid for that. At home a gallon of Crown white gas is probably the best deal.
