Is Ethanol a problem for our Corvettes and at what percent is this an issue?
Should we avoid it or?

E10 or the stuff you find at gas stations is absolutely not a problem on any car with a modern engine and fuel system.

From what I can tell, not a problem driving the car around like everyone else. Maybe an issue when going for max performance or something like that. On an unmodified recreational used car should never be an issue with up to 10% ethanol.
Storage is another matter. Ethanol has characteristics that can cause long term storage problems.
Lots of debate on that subject. 😂

If you scroll down to the "Similar Threads" below this window, there are umpteen previous posts on the use of ethanol blended fuels. I avoid ethanol blended fuel purely on spec. I have read many articles, both pro and con. Anything that has so many so called experts voicing supposedly scientific fact arguments in both directions makes me nervous. Phase separation, water absorbtion, corrosiveness, and shortened shelf life (plus the fact that ethanol supposedly is added just before it reaches the gas station, often by the delivery driver... appear to be the hottest topics... To each their own opinions on it's use....

As most likely a personal choice of whether or not to use ...
There is a pure-fuel app on this thread for your smart phone that can locate nearby ethanol-free fuel pumps ⛽️ especially handy when you are somewhere that you are not familiar with what’s nearby ...

Noticed that Costco pumps say 10% ethanol. Not sure what the others are adding.

Funny I just watched this the other day to learn more about performance. I'll just put it here for a reference:


Basically (on small engines anyway) non-ethanol will give better fuel mileage, non conclusive on sludge build up, don't leave it in a tank during storage.

From what I read about ethanol is that it is basically a cheap filler additive to gasoline. It costs 50% less to produce than gas but the kicker is that it only produces 50% of the power that gas produces. I don't put any fuel containing ethanol in mine!

Add Sea Foam to gas to combat ethanol especially when car is stored. Although here in B.C. Shell 91 has no added ethanol in it.
