Should I fill up my gas tank or put in $20 at a time?
If you can fill it and keep it filled
Depending on your tank size. By putting $20.00 in at a time will cause you to make more frequent trips to fill up. Where as if you fill up, you will save the gas which you would normally be using per each $20.00 fill up.
At the rate gas prices are going - I'd fill it up now. We're looking at $5 per gallon here by May.
Fill it up.
Fill it and when it gets down to half refill it. I do this so it's not as painful.
Fill it up. Less trips to the pump!
Depends if you only want 20 dollars worth I would fill it up and if you want a full tank just put about 5 dollars in. If you want half a tank fill it then drive in reverse around the block ten times.
You'll spend the same amount, so might as well fill up
Fill it up, then you won't have to worry about your fuel level.
In these rising gas prices, I'd put 20, keep my eyes open for a deal, then fill up on that.
you should fill it up whenever you have the chance, gas prices will continue to rise
