2004 f-150, 5.4. The gas station I use is going to 10% ethanol. In my owners manual it says not to use any gas containing methanol or damage will occur to fuel components or something like that. It doesn't mention ethanol, so whats the difference and is anyone using it or can we even run with it ? Appreciate any advice.

 

Yeah i guess that most of the stations now a days are already using ethanol in the gasoline. I got gas about a month ago and after filling up the tank i realized that it had 10% ethanol in it, I got a little worried but nothing ever happend.

 

Every single vehicle on the road can use up to a 10% ethanol blend with no problem. Nothing to worry about.

 

Guess that answers my question. Thanks partner!

 

I got 10% ethanol the other day as well. No difference at all.

The 10% ethanol is replacing the MTBE in gasoline which is polluting our waters.

 

Thanks Stealth, I had no idea, thanks for the information. Makes sense to me now. I get 10 cents a gallon deduction from this station so I didn't want loose it.

It's the E85, that you need to avoid. 85% ethanol. With the 10% ethanol, you will experience about a 10% drop in mpg, however.

 

The 10% mix has been used in Canada for almost a year, I've seen no change in MPG.

 

Generally speaking, most people will notice a slight drop in their mileage when using 10% ethanol mix.

 

i don't experience any measurable drop in fuel economy either...if 10% ethanol resulted in a 10% drop, i can't imagine many people using E85

 

Back when they would change every few months, I could tell immediatly as i track every fillup. It would drop about 1 mpg. Now they are using the 10% year round, so it stays at the reduced mpg.

 

E85 users get really bad MPG, but the price vs gasoline is cheaper.

 

Well dang, That's all I need, a 10% drop in mpg when I'm getting about 9-10 mpg right now. Maybe the price of the gas will go down using 10% ethanol, In my dreams. Thanks for the info bluejay.

 

Ethanol actually costs more. The government subsidizes it. It is for cleaner enviornment, so they say.

I'm surprised some of you didn't see a loss in mileage, there were threads about it a year or so ago when it was being introduced.
