Was sitting here thinking to myself, self,,,how flexible of fuels can someone run in a ‘flex fuel vehicle’? Would the car still operate on kerosene? A couple gallons of diesel in a pinch? What have people tried?
------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

The Flex Fuel alternative is listed in Owners manuals. My 2010 Pimpala "can" run on E85, not well as I have tried but will start and run on it. Fuel Mileage went from 25mpg(V6) to 14 on E85 and DANGEROUSLY Gutless. On E15 I drop to 23mpg, current 5-10% Ethanol and manage 25. On Pure Gas TWO Trips managed 32, station here used to have a pump for Straight Gas(87 octane), Enviro Idiots had it pulled.

YEP...."FLEX FUEL" , just means variations in alcohol content to GASOLINE... Not like a modified diesel that will run on diesel, kero, JP, etc...
You try anything else and the COMPUTER will throw a ...chit fit.... and you will get all kind of IDIOT LIGHTS flashing !

Could buy a mid sixties to mid 70s duece and half, can burn fuel, varied amounts of fuel with oil, ATF, gear oil and assorted other materials accorded to a List supplied with the Multi Fuel Engines!!! Do not run well either but will move the trucks!! We tried it out in 74, NOT GOOD!!

The multi fuel trucks ran great on jet fuel. If you wanted your flex fuel to run good you had to run 2 full tanks of E85 thru it without mixing so it could calibrate itself after that any mixture of ethanol would run fine. With the mileage baring depending on amount of ethanol in it.my moms Impala would drop from 30 - 32 down to 28 on E85 at the time E85 was about 1.50 a gallon cheaper

On my Chevy ran it for two weeks just for that reason to and from work thinking would adjust and be cheaper, NOPE did not happen, that is when tried E15+ same station and lower economy against E10, did the math did NOT compute.

way back in the 60's had a guy come into station and put 3 gallons of #2 fuel oil into car then top off with regular gas , 12 cents a gallon for #2 and 31.9 for regular gas , said it kept from vapor locking . Now with the flex alcohol fuels don't think diesel or #2 would do much except clog cat converter

Speaking of ‘vapor lock’, wasn’t it John Deere 2 bangers that required ‘power fuel’? A blend of #2 fuel oil and leaded gasoline,(maybe 10-15% fuel oil) to prevent summer time vapor lock.

I put some E85 into my flexible fuel ford PU once. Thought about checking the fuel tank for leaks.
