Just completed 310 miles on a tank, while driving an average speed of about 100mph on the autobahn.

 

Barely made 180 miles on E85, that was driving another 20 miles after the gas light came on.

 

ya, E85 is great for power but not so much with the mileage lol..

I got 25mpg going from TX to PA..

 

Just got 353.7 miles to the tank. Most that I can remember.

All freeway miles averaging 65-75 mph. Had to go to Sacramento two days in a row.

25.09 miles per gallon average. Filled her up with 14.1 gallons...I was on fumes LOL

 

25.096 MPG = good info.

 

I do not understand how you got 14.1 gallons into the car. Someone has mentioned that the tank will only take 13 gallons, +/- a couple tenths.

 

Im pretty sure the gas tank is 14 gallons DRY... He must be bone dry, then filling it up to the brim lol to achieve that 14.1 gallons' capacity.

350+ miles to a tank is ridiculous

 

I top off a couple of clicks and then I'm done. That's most likely how I reached 14.1 gallons of fuel....there's the filler neck that can hold a little bit of fuel. My fill ups average 12-13.5 gallons....I don't always go this low....just so happened to see the trip odometer over 320 and thought what the hell...lets see how far I can get....

Like I said earlier, I usually average 280-310 per tank so its not inconceivable to see my odometer reading 353.7 when I filled up (highway driving two days in a row to Sacramento).

CA 91 Fuel.

 

I have gotten 14.1 gallons into the car before too.

Also remember that car has fuel in the fuel lines still, usually half a gallon to a gallon's worth I believe?

 

I got 16.8 MPG on my last tank. Best this season. My car is warming up ATM, ready to roll out. Let's see if I can beat 10 MPG this morning. lol

 

There is a thread in EcuFlash that will give guidelines for better fuel mileage...

 

300 sounds impossible! I didn't even get to fill mine up yet but I heard from the previous owner about 200~250.

 

Not bad! I am at 357 miles right now, and yah I do need gas lol, but I am averaging 27 MPG, speeds very, with stopped traffic for 35 minutes, normal speed at the time I have been getting this 75-80 mph, also this was city driving too, I am quite content with the mileage.

 

Best I've gotten so far is about 250. All city driving, bone stock car. Couple fun pulls here and there but nothing crazy. Running Mobil 93

 

ffs fml.

Car is too damn fun on E85 for me to switch back to 93. I'm lucky if I can squeeze 100 out of half a tank of E driving like grandma
