Pros and Cons of running it until it's empty

[sponger]

I tend to wait until I see the warning light before I take it to the pump. I heard the other day that this is bad. Does it really matter?

[AVANT]

Running it till the light comes on isn't bad. The light turns on with plenty of gas in the tank. Running it down to fumes isn't so nice if you do it consistently.

I dont see how you can say pros or cons about it.

The electric fuel pump in the tank is kept cool by the fuel surrounding it. Continually letting it get below a 1/4 of a tank and you may have to replace it prematurely.

[Flashmn]

wrong, you can make internal fuelpumps work as external ones, fuel pumps are cooled by fuel flowing through them, aswell as lubing them, thats why you dont want to run them dry.

that and the crud in the tank is at the bottom! running it dry can be really bad.

Pro? ummm... if your broke your able to hold out longer before gassing up?

[Flashmn]

Well theres a pre-pump filter so thats not such a big deal.

Nothing really wrong with it until unless you are on the highway driving long distances.

I find the light comes on when there is about a 1/4 tank left, however, the most I ever filled up was 44 litres at the pump. Definitely do it before you hit the fuel reserve, which is about 1/8 the size of your tank.

I was told that on some new cars, when it goes low, it tells the computer to de-tune the engine management. It will flow less to the injectors to save fuel. I'm not sure which cars do this... but I still run low...

If you live in a humid climate it's best to fill up at 1/2 empty. The reason being is as fuel is used moisture is drawn into the gas tank then condensates at night promoting rust in the fuel system. In Houston 80 to 90% R/H is not uncommon.

From what i've heard, in the winter time (around here), it's best to have 1/2 or more in your tank to prevent moisture build-up. I've also heard that running it until it's at or below E can cause sediment in the tank to clog up the filter easier.

my fuel indicicator sits at full for about half the tank, then it drops considerably fast the rest of the way... can i get this fixed
