this summer. new policy will allow higher ethanol content in gas. severely misguided in my opinion. (a recovered ethanol fan) ---

I saw that too. Up to 15% rather than 10%. I wonder if it’ll affect anything on my vehicles (other than a slight reduction in fuel mileage)? ---

You have to be careful at least in Wisconsin and Iowa. They trick you with the pump labeling. If you aren’t careful you end up with the 15% regular. This is not good for some cars but you really have to study the pump label if an unfamiliar place. They got me in Iowa at a truck stop. My car can use it (although I don’t like it) but some cars can’t. ---

I wonder if there will be chains that don’t go to 15% ---

> [@Barkydog](#): > > I wonder if there will be chains that don’t go to 15% I imagine that there will be. Simply because 15% ethanol won’t be appropriate for some cars, and because those chains don’t want to be sued for engine damage, I suspect (or, at least I hope… ) that this won’t be universal. In the case of my 2011 Outback, the mfr specifically states that 10% ethanol is the maximum that should be used. ---

Kwik Trip in Minnesota, Wisconsin, and Iowa at least are the worst for confusing pump labels and they have the 15%. I don’t remember which truck stop in Iowa fooled me, Pilot or the other main one, but you have to look at those pumps carefully. At one somewhere, could have been Illinois, I had to go with the premium to avoid the ethanol. ---

IIRC the pumps at Kwik Trip and some others say “may contain up to 15%” ---

The one time I accidentally purchased a tank of gasoline containing ethanol my Corolla developed a too-high rpm idle problem a day or two later. So I didn’t buy any more. In retrospect I think the idle rpm problem was probably unrelated, just a coincidence. ---

From what I hear from Jay Leno’s YouTube vids, there is no gasoline sold in California that does not contain ethanol. It is a real problem for his older cars. Premium also contains up to 10% ethanol nationally so that won’t eliminate it. In my area you can buy ethanol free gasoline, e20 at some stations, e15 some places and sometimes e85. ---

Ethanol is a problem for a car collector that has a survivor/restored vehicle and wants to keep it original. Tester ---

At my local station the premium is non-oxy for boats, off road vehicles, collector cars, and of course my small engines. Yeah but not all premium is the same.
