IIRC - the upper limit was increased but the refiners for the most part haven't mixed 15% yet over warranty/liability concerns. Plus the fact we are flush with oil now.

Also likely that high density population centers have special gas in an attempt to limit ozone. Might be those mixes react poorly to open bowl vents on carbs as most cars are now fuel injected.

We have non ethanol gas here that's all I use in my older vehicles and gas yard equipment. But last year I forgot I had put ethanol in my burban in pa. Stuff went bad in the 5 months it was stored . Truck was missing running rough had to drain 15 gallons and use a couple at a time in my newer cars. Guess which is the fresh gas

Wont happen the car makers already expressed that problems with cars designed to run at 10% would be on the oil companies as they expressly state in the car warranty that a max of 10% is to be used . Only vehicles that can use 15 is flex fuel
