Is it possible to mix E85 with unleaded? If so how much?

 

I found this on Yahoo Answers:

You can fill up with E85 or unleaded at any time. One of the differences in the Flex Fuel vehicles is there is a sensor in the fuel tank to measure ethanol content and will adjust the engine accordingly.

You will find you get about 15% - 20% less fuel milage on E85. But most times, you about break even as E85 is cheaper than unleaded.

I havn't heard of any problems using E85 during the winter. I know that E85 is reformulated during the winter months, just like unleaded. There is less ethanol in E85 during the winter.

 

As long as your motor is an FFV, the EEC can calibrate and adjust any ratio.

 

my truck is can run on both but it was you must adjust the spark plug hight to run e85

 

ive read that the only diffrence is the lines/tank and maybe a tune but i havent read it....all it is is like what 120 octain....street legal race fuel lol

 

Suggest that E85 needs to be about 75-80% of the cost of regular unleaded to come out even as far as fuel economy. The value of any performance benefits is in the eye of the user.

If you're wanting to concoct the standard 10% ethanol blend for whatever reason, then it should be about 7.5 gallons gas per 1 gallon of E85. However, be aware that the regular unleaded may already be 10% ethanol. Here in MO, stations are now required by law to sell the 10% ethanol blend and do not have to label it as such. At any rate, not sure if this approach to blending would allow sufficient mixing before being pushed to the motor.

 

Here in TN, most gas has a note on the pumpt that it can contain up to 10% ethanol......I've not noticed much of a difference in mileage or performance though.....

 

Thank you guys. We are trying to figure out a cheaper way for me so I can take my truck to the Lima, Ohio truck show in May. My hubby was saying we could trailer it but I say no way.

 

I agree, you gotta drive your toys, that's what it's all about, right?

 

too many letters guy haha...jp...yeah ive filled up 50/50 and it works fine, and ive poured a whole tank of about 23 gallons of E85 and the truck feels to me like its running quicker...does anyone know what the estimated octane rating for it is? ive heard that its 105 octane or something crazy like that lol
on that note...
