Let's play the refuel game !!!!
 

How many miles can you get in a tank?

Rules: Honor system. No cheating.
Hypermiling ok as long as you disclose it and will be as a separate category.
For the extremists, have a gas can ready in the trunk.
Play at your own risk, I am not responsible for stranding you gas-less.

I'll start 500 miles. High but not too high to be the only person posting :p

My 100% highway driving trips to Orlando, I was able to achieve 26 mpg easily. So, with a 22.5 gallon tank, if I were to run it dry, I should have gotten 585 miles. On my first half down there, I know I had fueled up having gone about 520 miles or so, and that was averaging about 70 mph.

Local driving, I'm getting about 18 mpg or so and usually fill having only gone about 380 miles.

The big lady likes to cruise and doesn't like to stop and go.... :p

I've went over 500 a couple times but only on long road trips.

this reminds me of a Seinfeld episode with Kramer and a Saab test drive...

560 something
 

did this last summer when i drove to northern cali to visit family

LOL!!! indeed. I just bought a new set of 17" Kumho LX platinum's tuesday, and I cleaned my MAF (w/CRC) and TB totally, replaced the air filter and cabin air filter. About to go on a 2500 mile trip to the great state of Texas loaded down with 3 other people and a trunk full of luggage. Im going to fill up with jet-pep 92 and log the mileage after reseting all to 0. I will let you guys know the average when I get there, and when we return. my LS is all stock.

on my stock wheels i used to be able to go 500 (on my normal commute of like 75% highway) miles without having to think about refueling, but now with my new wheels and tires it seems like i have to think about it at like 440 miles now.

Wow, that must be nice.

I drive very little highway. My tank averages are usually around 18-19 mpg. I end up filling around 350ish after the light comes on with 50 to go.

wow 500 miles in 1 tank is like the holy grail in an SC

well unfortunately i just paid over $75 for close to 21 gallons of petrol ;)

wsup from northern virginia! I paid right around $75 for 21 gallons.

On average, driving to and from school and work I get 450 to a tank, but thats with about 40miles left on the menu.

:thumbup:

I pull 520 every week back and forth to work. I would hesitate to suck the tank bone dry and pull bottom debris into the fuel system.

Fuel supply
 

Isn't the fuel system (fuel pump) always syphoning fuel from the bottom of the gas tank? I don't think the syphon point if going from top to bottom or else the movement and swishing of fuel around the tank could cause moments of air being syphoned into the line.

I don't think you have to worry about sucking up debris on the bottom, it's more the stalling and possibly knocking of the engine as it's cutting off you have to worry about.

Sounds like a cool comparison/competition. I can get 500 miles easy out of a tank, but only if I can get 100% dino fuel. In some states its hard to get 100% real gas anymore and that 10-15% corn liquor gas really hurts the mpg.


But be careful pushing the limit - Running the fuel pump on a dry tank is not a good idea - fuel pump can burn out running dry.

This is very solid advice. The life of your fuel pump is decreased every time you run your tank very low or dry. Even little bursts of sucking air from a small amount of fuel sloshing around in the tank while taking corners starves the pump for lubrication thus creating friction and heat.
