Sunoco 94
I am starting to see Sunoco 94 pop up around Jersey; Planning on giving this a run for its money come car season, I have traditionally used Exxon 93.
Not looking to start an argument on brand of gas, octane, etc. Has anyone else seen this in their neck of the woods or run 94?

Other than ethanol attracting water, breaking down rubber fuel fuel system components, when reacting with oxygen to form corrosive compounds and breaking down to form gum and varnish affecting the Corvette “garage queens” I see nothing wrong with ethanol blended fuels…LOL !!

I'm in western NY, and we used to be able to get non-ethanol 93 octane, but that disappeared a few years back. Now, the best we can get is 90 octane, non-ethanol, and that's what I run most of the time, in all of the "family fleet". Once in a while, if I'm driving past the Mobil or Sunoco mini-mart and I need gas, I'll stop there and top off with their 93 octane, 10% ethanol blend.

I run non ethanol 90 in all my 2 & 4 stroke power equipment. Same fuel that they sell at the marinas. I ran it in my old RX7 with premix as well. We used to have Sunoco 94 locally but that went away with the economic down turn in 2008-10. Heck some of the local stations now only sell 92 vs 93. You have to double check when you pull up to the pumps.

If any water enters a fuel storage tank it will separate out in the tank before it is dispensed at the pump nozzle along with a portion of the ethanol from the gasoline/ethanol blended fuel. Additionally, the delivery system is equipped with particulate filters and fuel/water separators at the tank farm and fueling station. Alcohols along with other light distillates dissolve gasoline varnish. The synthetic rubber seals and o ring components on modern cars including C5s are not affected by the ethanol content in the fuel. Ethanol oxygenates the gasoline, it improves combustion efficiency and, it also increases the fuel's octane rating. Ethanol is relatively stable in liquid form at ambient temperature, I've never heard of it producing corrosive by-products when exposed to Oxygen.

Because they are putting more fuel into the engine and it has a better octane rating so they don't blow their motor. That makes more HP, but they still use more fuel to.do it.

Something to think on, I tuned my car for WOT using gas from a line of stations that was more prone to giving my friend's ZL1 (LSA) Camaro knock. I then run the car on better gas. My thinking was I'd be less likely to have any knock running the better stuff during the hot summer. Granted my timing is also conservative.
I have a Sunoco around the corner. However, it is an OLD station and I am bit nervous to use their gas especially in a performance build due to concerns of their tank having water in it. The Corvette gets gas from newer higher volume stations. My daily truck will get 87 Kroger gas at times.

There are a couple of considerations using ethanol based fue. in a C5. When GM was developing the LS1 engine all the fuel used for all there testing was non-ethanol gas (we had many Milford engineers and programmers in our local club at that time). Another is the amount of ethanol in today's gas can vary from 5-15% and finally the PCM used in the C5 was a 16bit PS2, it wasn't until GM started with a 32 bit chip that 85% ethanol fuels were tested. You can run 85%E in a vette but lots of programming needs to be done to run it.
