accidentally put e85 in our Mazda 3 (not a fex fuel car)
OK, so yesterday my wife and were on our way home. I'm driving her 2010 Mazda 3, didn't want to stop 'cuz my she's touchin' my wiener, but the tanks below a quarter. As you might imagine my mind is in the wrong place. I put 10 gallons of e85 in a 12 gallon tank. Talk about a mood killer! Drove the rest of the way home, about 40 miles, expecting problems but NOTHING. Ran perfect, engine light never even came on. I figure I will just put gas in it every day to dilute it.

Anybody else run e85 in a non flex fuel car? I've never heard of anyone ruining a newer car with too much booze in the tank, have you?

Most cars will "run" on e85 but the high alcohol content WILL destroy most of your fuel system components. I would say to at the least run through that fuel as quickly as possible.

That's OK. Pfizer makes a pill for that...

You might be ok, but I see high repair bills in the future. Orings and flex lines will start to go. Fuel pump maybe. You had another 40 miles till home. Would have just went there.

e85 will run a little lean with no tune... I've ran e85 quite a few times in my turbo cars, and it usually takes around 25% more fuel to equal the same air fuel ratios.... Just be easy on it and put regular gas in it asap... will take a lot more than one tank to corrode anything those are all myths about e85

Do not worry about it....
Do not make a habit of it but as long as the car runs OK then there is nothing to worry about. Would not be a bad idea though to drive the car to a low tank and get that fuel out of the system in a realtively quick fashion. Just do not let it sit in the system for weeks.

There has been no harm done though.

It is not about corroding parts. It is about incompatible rubber in the fuel system. E10 is different, most rubber can handle 10% alcohol but not 85%. The problem that most flex type fuel systems face is finding a suitable rubber to handle gasoline (oil) and achahol which is at the other spectrum. There is a rubber (Kalrez), it is about 10 times the cost of EPDM or viton rubber.

We run E85 in our race cars at my work. And you can run E10 with, just a New computer program, but you can not go to E85 with just a program. The fuel regulator, flexible lines, injectors, and any orings or other rubber parts will be affected. The rubber swells with E85.

I hope you get lucky again and no side effects will happen to your car. Like Tbird said keep a full tank as much as possible with regular gas. The only other thing is to drive out the tank of gas ASAP to avoid the achahol sitting with the rubber parts.

Good luck

with tech nowadays the handles at teh pump should interface with an rfid on the gas tank hole and the pump could give off a warning if it wasnt an e85 car.

What happens if I accidentally fuel my gasoline-only powered vehicle with E85?

Although your vehicle was not manufactured to run on E85, no problems should occur if you mistakenly fuel once with the alternative fuel. The largest difference between an E85 powered vehicle and a gasoline powered (legacy) vehicle is that their computer modules are meant to read different amounts of oxygen within the fuel. E85 contains a higher amount of oxygen than gasoline and E85 compatible vehicles are made to read that higher amount. When a higher amount of oxygen is read by a gasoline powered vehicle, your "check engine light" may appear. A number of other parts on the FFV's fuel delivery system are modified to be ethanol-compatible. The fuel tank, fuel lines, fuel injectors, computer system and anti-siphon device have been modified slightly. Alcohol fuels can be more corrosive than gasoline. Therefore; fuel system parts have been upgraded to be ethanol-compatible.

Ultimately it is a drivers choice, but we do need to be firm in recommending that only FFVs use E85 and to state that we are not responsible for damages.

E85 needs to be separated completely and or very visibly identified to prevent this from happening.Maybe they need a new special fuel nozzle for this crap.SEMA is working hard to protect from this type of damage.
http://www.sema.org/sema-news/2011/...-use-of-ethanol

Crap; may be harsh as the fuel is good for what it was designed for but not for older vehicles.Without potentially costly upgrades.One more thing to ponder is the cost to operate based on consumption; general rule of thumb is it takes 2 x as much alcohol to run an engine as gas.3 times as much nitro-methane as gas.Each does make more power and runs somewhat cooler but the bottom line is you will burn more to go the same distance in an older vehicle unless you decide to go aftermarket EMS and learn a lot of stuff or pay someone that knows the stuff to properly tune your ride for ultimate performance and efficiency.
I love the smell of nitro in the morning..

The manual is pretty brief in the fuel section. Only real warning is not to use gas with less then 87 Octane rating.

At the pump there were three nozzles, the one I would have chose was out of order, I was left with 50/50 chance to get it right, go figure...
