Here in MA it’s available at 94, 98, 100 octane (one higher too I think) and yes it’s considered “racing fuel” but will work just find in small engines.
Here they sell it in 5 gallon containers, which I will be looking for next weekend. Will stock up on as I can and add stabilizer so it keeps.
It’s 87 where I get it, and that’s fine as it’s also at around 4700 feet. I actually run the 85 out there too, but my station I usually go to just put in “clear gas” alcohol free pumps and so I fill w/that + fans for return trip. I got 20.2 mpg in the Silverado on the last trip back on that and that was doing a solid 75 average 95% of the way (435 miles). It’s cheaper there for pure that it is for alky gas in CA next to the refinery.
My Silverado is a flex fuel, so I can run E85. Did a couple tanks, mileage was about 15-16. I do like that in a pinch, you can make 1000 gallons of fuel with 150 gallons straight gas...
