yes the classic never die motor. one day i emptied my tank and put 15 gallons of E85 in it. i had just replaced my fuel pump with a ethanol compatable one thought id try it US farmers are better than any import i say so like i said i filled the tank to half full 15 gallons from empty. i drove into a parking lot and drove around for a while. after ten or so minutes feeling that the new stuff was in the system i hit the road. side roads first then the highway. the old van 1985 ford ran so well it even sounded different like it liked it. so after i ran out of this 15 gallons i filled the tank with 30 gallons of the farmers stuff. dam thing ran like a top gas milage was 8 % lower. its been three or four years and im still running the same. after finding several engineers at ford and as many techs as i could 50 or so in that time no one can say why this old cargo van can run anywhere near normal with E85. what i got out of it was the brain cannot adjust for the different fuel the timing cannot adjust properly and the seals in the injectors will fall apart and the injectors will not work right need to be replaced with bigger ones the fuel pump will also fall apart but i replaced it with a compatable one the fuel lines would fall apart but mine are metal lines so they wont  . it seems there are enough people here that i may get some good tags on this issue. what i want to know is why this vehicle without modification can run on E85. |

The main reason you are getting so much conflicting information is that most of those people don't know what they are talking about.
Ignition timing on E85 is essentially identical to gasoline --- no mystery there.
That old of a car probably ran a relatively rich mixture on gasoline and if it has any adaptive ability in the engine management it is compensating to give you a workable fuel air mixture.
E85 has wider flammability limits than gasoline it will run far richer than you can get away with on gasoline, and it will run far leaner on E85 than you can get away with on gasoline.
The higher octane also gives you a safety cushion so that it does not ping if run lean.
The fact is most cars will run on high blends of E85. I have an 1986 and a 1988 car that both will accept high E85 blends in hot weather, although since they have no conversion of any kind they do not like it much in cooler weather and will not start in cold weather.
There is no such thing as fuel system components being ok for 10% ethanol and not being compatible with higher blends. It either tolerates ethanol or it does not based on our experience with hundreds of cars that run full E85 or high blends of E85.
There were also some multifuel cars made during that era as lots of locations were running gasohol to extend limited petroleum supplies with ethanol, and a few were what we would today call FFV's although the term did not exist then. I think the Ford ranger pickups had a mulitifuel version about that time period.
The older electronic engine management systems in some respects were more flexible than the modern ones, as they did not freak out if some sensor was out of range, it just did its best to adapt.
It would be interesting to see what your AFR is with a wide band O2 sensor on the stock computer now that it has a long time to adjust to the fuel.
It would also be interesting to see the first 6 or so digits of you VIN number to see what its code is. Was it originally a fleet vehicle for the government or post office or was it sold directly to a private party when new?

x2 on most people are clueless, havent run it, dont know the difference between methanol and ethanol, and think they are the same thing with the same properties and drawbacks.
For what its worth, the only thing on the 70 GTO I have on ethanol that didnt like the fuel was an old accelerator pump, the gaskets, fuel lines, tank, carb, everything is just fine with ethanol. Changed to a more modern accel pump diaphragm and it runs good.
Its good to hear you arent having problems like most people way you will. Welcome to the club.

I have seen a lot of folks do just what you have Green -- for most it worked out the same as long as they were pre-'96 when the OBD2 computers came out like Hotrod referred to (most '96 and later will throw a check engine light due to a sensor giving signals not expected by the ECU).
My guess is you let it idle a minute or 2 before takeoff for full power to come up? |
