I did some driving this weekend around Southeast Texas and conducted a study on the affect (or is it "effect"?) of gasoline with 10% ethanol as opposed to gasoline with none.

In Houston, Texas, for some reason, we appear to be required to utilize gasoline with up to 10% ethanol. In my hometown of Beaumont, Texas, the gasoline is not identified as having any ethanol.

Bottom line,and this is ALL HIGHWAY DRIVING, when utilizing 10% ethanol gasoline my 2001 Disco got me 13.72 mpg with an average of 70mph. When utilizing regular gasoline I got -wait for it - 17.75mpg at an average of 70mph!!!!!

That is an insane difference! (Frankly, I am just excited that my Discovery can get almost 18mpg - my typical (in city) driving is <13mpg.

 

Regular, being high octane with out ethanol?

 

Yes, in both instances I was using premium grade Exxon.

(I know that some people here push Shell gasoline, but my old man works for Exxon and thatgasolineput me through school .)

i've experienced the same thing, only im in illinois, near chicago, and anything west of me gets ethanol, and i get the same bad mpg

 

Ethanol is a scam!!

You use more fuel than 10% ethanol makes up for.

I went from 14mpg intown to 11mpg, and from 16 to 17 mpg hwy to 14.5 Best mpg hwy.

 

I believe it is "effect."

 

Yes the effect of a feel good law that makes no sense.

 

I went to shell today and $3.60 gal I spent $61 bucks to fill my tank I was at 14 MPG but I dont care as long as its running! I just keep thinking someone one daywill have a mode for our trucks that will get us 30 MPG or more but, I will still sport my sexy gass bi#$%# till then ;D or start making my own gass!
