Non Oxy Fuel?
Greetings,
Our Corvettes are designed to run on ethanol blended fuels. I use (E10) 93 octane gas in my C5 Corvette. Would it damage my Vette if I used a Non-Oxy Premium fuel instead. One that had no ethanol in it at all? Would it hurt the engine or catalytic converter? I am getting ready to store my car for the winter and I have heard of problems with ethanol blended fuels sitting for a few months in gas tanks. One being phase separation.
Your feedback is appreciated.
Thanks, Edgemereski

Our cars would have need designed to run on straight gas or gasoline/MTBE blends. MTBE was an oxygenator which helped improve combustion and raise octane levels. It was designed as a replacement for the old lead additives in gas. Due to pollution issues (getting into ground water), it was replaced by Ethanol about 15 years ago. I've had my C5 sit for extended periods with E10 in the tank with no ill effects. No ill effects on power tools like chainsaws, mowers, etc. either.

You can run either E-10 or non-ethanol gas in the car.

The only difference is your Corvette will get slightly better mileage, the engineers in my local club (work at GM,Ford, Chrysler, etc) tell us that the additive package in today's gasoline lets us skip the fuel stabilizers for the winter. Have not used them in years with no ill effects. The problem in my area with ethanol free gas is waiting in line for all the lawn maintenance companies filling up their equipment. My generator quit this summer and took it in for repair, The tech told me to drain the E-gas and use non E gas or pay to have it repaired every other year.....Michigan has its own blend of summer gas.

Non-oxy is all I run in mine. No need to add any stabilizers for winter storage. I believe I read something a while back about non-oxy fuel possibly being better for fuel tank level sensors. I run non-oxy in my Corvette, boat, and all my small engines.

Each state may have different rules, but in MN the pump nozzles are specifically labeled as non-oxy or non-oxygenated. If its not labeled, the gas is an ethenol blend. Most stations do not carry non-oxy gas. The State's goal was to have this fuel used only for classic cars, boats, lawnmowers, etc.

Our cars were developed and built before E10 was a thing. I will say this: when I had my new 2000 six speed coupe I made a point of driving one entire tank following the instant fuel mpg twitches and keeping the pedal input low I pulled over 440 miles from the tank. I have not been able to land even close to that with my state mandated E10 fuels. I'm excited if the car gets over 330 from a tank. Typically a 16 gallon fill when I go.
