Do you fully fill your tank or partial fill?

[BEEMDUB]

I always do partial fills, 30 bucks at a time, and closely watch my MPGs...Is there any benefit vs risk with filling your tank all the way vs partially filling the tank? I also heard that its bad to repeatedly let the gas light come on?

When your gas light comes on it means your fuel pumps are working harder is what I heard.

I would always fill up completely and don't let it get below a quarter to avoid fuel pump strain.

The light isn't necessarily an indicator that your fuel pump is working harder. It means you are low on gas - which in turn does mean that your fuel pump might be working harder.

It is also bad to let it run low because you risk the fuel pump strain, running the engine dry (out of gas) which can cause damage, pick up sediment from the bottom of the tank...etc.

Just don't let it get below a quarter, doesn't matter whether you fill it up partially at a time or not - just watch that quarter...

I usually fill up when is 1/4 to 1/2 a tank usually 1/2 a tank tho dont want to damage the pump since the gas cools it or pick up any crap in the bottom of the tank

i fill up everytime and i fill when the light comes on. did that with the my 99 trans am that had 155000 miles and no fuel pump probs ever

I do a full fill up. But I always let the low fuel light come on and haven't had any problem. Putting gas in it every two or three days just sucks IMO.

I'm usually a fill 'er up kinda guy. I wait for the light to come on and then go fill 'er up
