Fuel Octane

Eric - rain/mud is the clue. Been raining for about the last seven days and I'm stuck with three jobs that need dry weather.

OK, I could be pricing another one.

The presence of ethanol is certainly not responsible for multiple MPG loss.

Okay for you, Mr. Smartypants. It's not about what's really going on. We're trying to find someone to BLAME.

Just blame me, that's what the old lady does.

Considering that ethanol is 1:1 miscible with water, that assumes an awful lot of water entering the fuel system!

Josh - I am pretty confident the odometer is accurate to within 1.5 percent.

that is true, but when you're dying for water in teh fuel, alcohol burns a heck of a lot better than water.
and it may have been a bad tank of gas from the station, it wasn't my usual place.

and i always check my odometer, after i noticed that my F150 was off by a full 10%

i agree, but NEVER use the discount brands, as they will destroy your fuel economy and your engine. around here that means ARCO and 7-11/CITGO. don't know what brands are near you, but you know which ones.
funny thing is, i ran that trash in the F150 for awhile, switched to good quality fuel, and saved enough fuel to actually spend less money per mile when using the good brands
i would never have thought to switch until i vowed never to set foot in that store again. ever. but that wasn't a fuel reason, that was personal

Yeah those brands though cheap are really just crap.

I never really check my fuel mileage.. Its dissapointing with gas at $3.90 a gallon but if I got to shell, bp, amoco, or sunoco my car definetley runs smoother than it does at citco 7-11 etc. Everything down here is E10. Just a little fyi 100 octane sunoco gas really wakes an engine up. I usually only put a quarter tank in from empty just to keep eveything burning clean. I can feel the difference too bad its 6 bucks a gallon.
