I hate put gas in it i put 50 doller it last for one day?

I have a 2000 ford expedition xLT i I waste a lot of money on gas Its eat a lot i don't know what's wrong with it

First of all, how far do you drive each day? At $2.50 per gallon you should be driving at least 300 miles in order to use up $50 (15mpg)

My next guess would be someone is stealing your fuel. Do you have a locking gas cap?

If you don't drive hundreds of miles and no one is stealing your fuel then it has to be a leak. Your vehicle couldn't use that much fuel without flooding and dying. It could be leaking from the fuel line, which would only leak while driving. Do you smell fuel?

At that rate, I suspect the tank has a leak or something.

You might have left the four wheel drive on

PUT IN 100 DOLLA THEN AND IT LAST YOU TWO DAY

WELL DONE
