Which way saves more gas?

Question

I have been putting just 25.00 a shot in my SUV ..two people at work say that you save more gas by filling up the tank.. I don't see the logic..

Answer 1

how can you save bye filling it up when you fill it up you are carrying more weight you are right dont lission to them.

Answer 2

Not sure if its true, but I have heard from many sources that filling you tank up when it gets to 1/2 a tank saves gas because there is less air in the tank so the gas does not evaporate. Its not really costing you anything more except 1/2 a tank so give it a try and compare your MPG

Answer 3

seems like you are doing the right thing, and I can't see the logic of carrying around extra fuel.

every gallon of gasoline weighs about 7 pounds, so when you fill your gasguzzling SUV with a full tank, you are carrying the equivalent of one extra person on board.

by your practice of putting just a little fuel in, your SUV has to exert the horsepower to transport a baby rather than a full grown adult

Answer 4

filling up the tank saves more gas

>> say that you save more gas by filling up the tank.. I don't see the logic..

They may want to invest in the gimmicks that runs car on water too.

Forgetaboutit.  It makes no difference.  In fact having the tank full (heavy) uses more gas.

There are few thing you can do to save (or maximize) gas MPG. First get a tune-up.

(1) spark plugs

(2) spark plug wires

(3) distributors, coil, rotors (if you have them).

(4) new air filter

(5) PCV

(6) correct tire pressure

(7) clear the trunk of useless heavy items

(8) spray clean MAF sensor.

Forget all those "SAVE GAS" scams.  This was on NBC morning TV show.   The difference is as much as 38% (their claim).  There are very simple rules to save gas:

(1) drive slow - not too much past 55

(2) accelerate slowly

(3) don't brake unnecessarily

(4) use cruise control - whenever it is safe to do so.

Don't coast - it is NOT safe (to coast in Nuetral) and it does NOT save gas.  It only saves gas, if you are planning to slow down (exiting, tolls, traffic).  Coasting then accelerating again is LESS efficient than just cruising.

The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic).  That's 41 MPG (94 Civic 187K miles).  Actually I was speeding at 72 MPH so I could do even better at 55.

WOW !!

Good Luck...

Answer 6

Filling up the tank saves more gas, because then you drive to and from the gas station less often.
