I can already tell you what is going to happen.
You can run any gasoline engine on E-85 with no conversion kit, you WILL loose MPG, your fuel pump WILL die sooner than later.
I ran E-85 in my '89 Camry for 3 years because I was dirt ass poor after my divorce. I only drove it about 5,000 miles a year, fuel pump died and I scraped the car. Only paid $500 for it. Car only had 180k when I bought it from it's original owner.
I also ran E-85 in a work van for almost a year, a Ford Econoline with the 5.4L Triton V8, ran like a raped ape until the heat of summer and would not start in the morning once fall came, but the conversion kit would take care of that.
Also ran it in a Volvo turbo wagon for a few years.
Ran it in my lawn mower, don't do that. It will not be happy and you'll need a new carburetor.
The only benefit of the conversion kit wold be cold starts and hot days. On hot days you need more fuel because the ethanol evaporates inside the intake and never reaches the cyclinder, on cold starts you need more fuel because ethanol has less power than gasoline and you need more of it to start the engine.
I have an app on my phone to keep track of MPG, if you are really committed to this and reporting back to us please keep track of your MPG using an app.
So run 3 tanks of E-10, what's your MPG average.
Then run 3 tanks of E-85, whats your MPG average?
5 tanks of each would give you a better MPG average, but I do understand the time it would take to get those numbers might be prohibitive to you and your situation.
