I have heard there's some ATS-V's that are experiencing smoke during WOT. One theory was that all of V's were running high % of E and causing the turbo seal accelerated wear. Not sure if that's the cause, but I can imagine the possibility of this happening. I tend to run 93 more than E30-E50, and factor in traction limitation if I'm not on a sticky tire.

P.S. I was never told what high % of ethanol equaled.

I've tested water in Gasoline, but always thought that water in Etholine was different. Maybe I'm over thinking it? I tend to this as an engineer...

I’m not a scientist by any means but if you purchase an ethanol tester kit you might be able to get a good idea if your fuel is good still. The kits work by adding a little water with your fuel into the kit/container. You shake the container and the fuel will separate from the water. Where the separation occurs in the container will correlate with what your ethanol % is. If you’re ordering E85 by the barrel it should be exactly E85 or whatever it is that you ordered. If you use your test kit and you’re getting a result lower than what you purchased then that should tell you water is getting absorbed into the fuel. Or you got a bad barrel I guess. Assuming quality control isn’t the problem a reasonable explanation your fuel reads a lower E% is it’s not as pure as it should = water is being absorbed = less fuel and more water into your test kit = test kit shows a lower E% than what you ordered. Maybe that isn’t 100% scientific but it should give you an idea. I recommend reaching out to the manufacture describing your situation (how old the fuel is, sealed/never been open, where it’s been stored, temperature and humidity of where it’s stored, etc) and see what their opinion is. If you used a reliable company they should stand by their product and tell you the truth one way or the other. They want happy customers using their fuel and they don’t want pissed off customers who blew their car up with fouled fuel.

The fuel is from VP so I'm confident in the quality from the start. It's just been sitting for a year or two and I know that high E fuels trend to absorb water.
