357 miles and the E light has yet to come on... the last time the E light came on, I filled it about 2 miles later... and I put in 10 gallons. So going off of that, when the light comes on again, I should be able to do at least 50 more miles (60 if I want to push it) bringing my tank total to 407, which rounded up is 34 mpg! 3 over the EPA rating!

good stuff... after the throttle controller I am literally at 300 per E light... thats with 70% city

John I'm not really understanding your logic. You should run the tank down and fill it up until the gas pump auto shuts off. Drive your car and then next time you get gas go to the same gas pump again. Pump until it auto shuts off as before. Then divide how many miles you have traveled by how many gallons of gas it took to pump. That will be accurately your MPG for that tank.

So if you travel 400 miles and it took 10 gallons to refill that would be 400/10= 40mpg

Rob,

Sorry I didn't clarify, but that is exactly what I do... divide miles driven by gallons it takes to fill. I'm at 365 miles and the light still hasn't come on yet.

Is it pretty consistent for you when the E light comes on?

Nope there is not consistency to the light. Or at least not in my car. Let us know how many you get in that tank. Good MPG's are money in the bank arty:

Well the auto shut off at the gas station isnt completely accurate either. I can put about $3 more in my tank once it shuts off.

Of course you can overfill your tank. You can fill right up to the neck if you want. That is exactly why I said you need to use the same gas pump. Also you will want to pump slowly. The reason for it shutting off prematurely is you are pumping to fast and the gas is not flowing into the tank fast enough. It's backing up in the filller neck and choking off the nozzle and shutting the pump down.

If you are one who doesn't hold the handle while pumping and use the little tabs you will notice there are two. One to pump slow and another for full pressure. Use the slow one.

I don't think it matters when if the auto shut off occurs simply because the I will still use the amount of gas pumped divided into the miles driven... or does it matter?

It matters alot. If you drive 400 miles and for some reason the pump shuts off at 9 gallons you calculate 44.44mpg. Now say that pump shut off prematurely and in actuality it was suppose to shut off at 10.5 gallons. You really only got 38.09 mpg

Using the same pump, pumping slowly and taking the average over several tanks ensures that you are getting as accurate a mpg reading as you can.
