I also heard about the condensation and I heard when you drive near empty, you suck in alot of containments at the bottom of the tank.. is this true? I change my fuel filter every 30,000 miles anyways.
How many of you, fill your gas tank ALL THE WAY?

I've got a great life actually. Nice house, great job, great wife, cool 4 year old son, and I'm driving a Corvette. How could I improve on that?
Just a question-- how does the gas pump know when the tank is full? Is there a pressure sensor at the tip of the nozzle?
The reason I ask is because there have been a few times when the pump stopped itself prematurely on my car (short by about a gallon or two). I could tell because the fuel gauge needle was just short of the "F". I think this might've happened to me again today, but by just a very small amount. If this is the case, does the pressure increase if I hold the hose (not the actual nozzle) higher to allow better flow?

i break out the 1 way valves inside the gas necks of my cars so i can fill them up to the brim, im talkin all the way to the point where the gas is as the level of the threads on the gas cap.
gas tanks have built in air pockets at the top of the tank to allow for expansion. you cant fill a gas tank up to 100% no matter how hard you rock the car or whatever. its impossible, so i just fill that sucker to the max and dont worry about it.

You can improve that by buying me a new Corvette. I actually grew some balls when I sat inside one at the auto show.. it was some special sport model.. it cost $80,000.quote:

I drive until the fuel light comes on. I go find the cheapest gas I can find within reason and fill up the gas tank until it clicks. I go ahead and top off to round to the next dollar. I do not fill to the brim because I have seen others spill gasoline on the ground doing this. Since I only fill up once every two weeks, an extra 0.5 gallon isn't going to make any difference either way on number of fillups.

It's not about filling the tank 100%. It's about squeezing in as much as possible. For some reason I always end up owning cars with puny gas tanks. Well, my Scirocco had a decent size tank -- good for 600 miles at highway speeds. My Audi quattro has as small tank (quattro penalty). Half a gallon extra makes a real difference in cruising range.
I find people with the fullest tanks and then siphon their gas.
Excellent response Patman!quote:

Good to see folks enjoying life in todays world.
All the doom and gloom the Media trys to project these days.
But back to the subject on hand. I drive till the Fuel light comes on and fill up my Car and truck everytime. Thats so I can get the MPG down for my log and not have to stop more often.
Take care, Bill
The fuel pump is ALWAYS sucking from the bottom. You won't get any more contaminents driving on a near-empty tank than you would with a full one. Anything that settles to the bottom will make it's way to the fuel pump sooner or later anyway. That's what fuel filters are for.

But you'll still heat up the fuel pump a lot more if you run the tank empty, since the fuel does indeed cool the pump. With my old 98 Formula I could hear the pump get a lot louder when I ran it close to empty. I don't want to tempt fate with my Corvette, as it's got two fuel pumps. And they are not cheap to replace!
