Ethanol is not just an "additive". Years ago tons of people were converting their vehicles to run on straight alcohol as an alternative to gasoline; and it will still work.

Great. But are all the kinks worked out of it? Or what?

Thanks for the interesting real-life information WEOH. And here's hoping your fuel prices drop for you again.

We know what works and what can cause codes.

Here's another blender vehicle, a bone stock 95k mile 2002 Ford Escort ZX2 5 speed. We run 6 gallons E85 blended with 4 gallons E10 89 octane and it runs excellent, gives anywhere from low 30's to mid 40's mpg calculated depending on how lead footed my wife is that week :) Each tank fill up saves us ~$3.50 which buys a jug of milk and a donut or two. That's based upon a realistic price spread as some stations think E85 is gold and worth as much as E10 and others give us a break with a 60 cent price spread. Can't wait for the price spread to go back to normal so E85 is dirt cheep again. Will that ever happen? Hope so :)

WE0H, thank you for your detailed information.

It is nice to see that Prius can do so well with extra Ethanol content. Sounds like running E50 or so on stock Prius should be no-brainer.

Thanks, WE0H! It's good to know that the Prius runs fine on ethanol, in spite of what the Chicago anti-ethanolics claim.

I run a Change2E85.com converter. It runs perfect. I also own a few White Lightning converters but haven't installed them yet. I have one or two more Change2E85 converters also :) Whenever I can find them cheep I buy them. I find the stock setting on the Change2E85 converter on my Prius is a bit rich. I use a ScanGauge to monitor short term and long term fuel trims and it shows the computer cutting back the mixture quite a bit on a start up and shows it running slightly rich once the motor is past it's warm up cycle. I believe these types of converters use the cold start feature for every start up and as you likely know the Prius is constantly shutting the ICE down and restarting it as needed while the car is driven. There is a 20% window that the factory computer can richen or lean the mixture so I have quite a bit of room to lean the converter to up my tank average gas mileage. It runs 46 mpg on straight E85 and right around 50 mpg on 87 E10. A bone stock Prius can run E57 with zero codes and only drops 1-2 mpg verses 87 E10. This motor really likes running on the higher E blends, although it is a Atkinson Cycle motor and has a 13:1 compression ratio. As we know higher compression motors drop the mpg's less, if at all, running high E blends.

Those E85 converters work perfect. I own a few of them and run E85 in many vehicles with excellent fuel mileage in all of them.

Hell they still do run on 100% pure Alcohol .... that would we would call "Top fuel Dragster" which burns 100% pure alcohol .........if you get the compression ratio up high enough it will burn good my engine I tore apart after burning E10 looks like crap it is not made for the older engines or fuel lines they can be steel lines and the will pit. This is the second engine I have seen like this with less than 100k on it the injector on both were pluged severly...so thionk about it when you start running all this crap on a constant basis through the engine ... In WWII they use water inection as a boost for 30 to 45 sec at a time but theyy were also running 140 oct or higher...

"But then wouldn't it be cheaper (and more reliable) to buy a new FFV vehicle and push the limits on E-85 up? "

Not really. Actually people that convert are losing much less mileage than a conventional FFV. Many are in the 10-14% area. I even know of some that are down around 6%. You will not find that with most ffvs.

As long as the conversion covers the entire fuel system, exhaust, catalyst, sensors, and computer, everything would be good. I have seen what happens to engines that weren't spec'd for more E than 10%. Of course warranty was out-the-door and down the street to the repair shop.

But then wouldn't it be cheaper (and more reliable) to buy a new FFV vehicle and push the limits on E-85 up?

What do you think?

There are thousands of posts from people who have converted their vehicles on Planet E85

daily run, if there are a "ton" of people converting there vehicles to run on ethanol, does that mean there is 10 - 13 people converting there cars?

I am not a fan of ehthanol. It will burn fine, but it burns hotter than gas and a "normal" engine set up will not last running a high percentage of it. It also does not produce as much energy as regular gasoline.

I use up to 40% ethanol on every fill up. Works great.
