Has anyone else felt the loss of milage since Ethanol?

not really nothing,this gas today is crap.all i know to do is run a bottle of fuel injection cleaner in a tank of gas,do this like a oil change,every 3000 miles.

Thanks... I have tried some fuel additives but had an insignificant change in mileage, but when I added in the cost of the additive, my cost per mile went up. I have not tried fuel injection cleaner but will try it on my next trip. I go 600 miles almost every weekend so I can go through a tank of gas at full normal temperature.

invest in underdrive pullies.

Never heard of them... what is an underdrive pulley and how does it work? Thanks for the reply

By slowing down the acessories and freeing horsepower while reducing workload. Aspracing.com

aspracing.com is old! showing last date of 2008... three years ago. Also, not much on it. Thanks anyway for the idea. I agree, slowing down everything will save a minute amount of fuel but it would probably take 1000's of miles to pay for the part and labor.

At a 15% increase in fuel mileage at 12000 miles a year they pay for themselves in under 3 months. At $3 a gallon

I must not have seen the right item. What is the item number and how much does it cost. A 15% increase would be amazing as a BullyDog only says I can get 10-12%

5.4 engine or 4.6? I just sent you to asp because their website is the most informative. They aren't the cheapest nor the best

5.4. Thanks
