Coleman Fuel (white gas) and octane boosters = Emergency Fuel?

1 station about 25 miles away. Nothing closer.

In Iowa they blend 85 octane gasoline with 10% ethanol to get 87 octane fuel. 85 + 15% ethanol gets you 88 octane fuel.

 Thirty miles to closet big store here.
Oh no 25 miles.  
You big city people are spoiled.



I can't remember if it was acetone or naphtha that you could dissolve mothballs in and get a hot octane boost.

Go to the airport and buy 10 gallons of 100 LowLead. 100 octane, with additives to keep it stable for a long time. You’re going to pay $4.50-5.00 per gallon but it’s better than the quart cans at the farm store. Smells better, too.

For 'liability reasons', the local FBOs at the local airports will no longer sell avgas unless it is being pumped directly into an aircraft fuel tank.  No more five gallon cans or using it in your auto.

My garage is 80* - 95*- 24/7 - 300 days / yr … how would that affect the longevity of the canned gas or ethanol free w/ Stabil in a steel jerry can ?

Surprise! I found a web site www.pure-gas.org that lists places selling ethanol-free gasoline, byt state. I thought it was completely unavailable in my state, but there are a few smal engine and lawn equipment shops that sell it -- by the can, not from a pump. I called the shop nearest me and asked if they still have it. They do.

Price? A mere $27 per gallon.

So I'm back to removing the ethanol for mowers and small engines. But ethanol is an octane booster, so then I had to research how much the octane drops after the ethanol has been removed. So far, it appears the answer is 3 to 4 points, which means if I want to purify my own gas I should be buying at least mid-grade, or maybe premium. Hey, it's still cheaper than $27/gallon.

From what I can tell they use a Wiki-esque system of public submission so take everything there with a grain of salt and do some independent confirmation.

VP Racing Fuel master table. Pay close attention to the Unleaded listings with "No" in the O₂ column (non-oxygenated = no alcohol).

https://vpracingfuels.com/master-fuel-table/

C9 and Vintage Unleaded are $68 for five gallons, right at the $70/5 gallons that French mentioned for Sunoco. No idea on shipping cost. If you don't have a Sunoco dealer you might be able to find a VP dealer somewhere nearby, so... options.

Vintage Leaded is only eight bucks more but make sure you never, never, ever pour any of it in your car's tank unless you like replacing catalytic converters and oxygen sensors.
