Full tank of Gas? How much weight does it add, ...or does it make a difference? Options

[amysmojo]

How much weight does a full tank of gas add to our Celicas? Does it slow them down at all, or does it even weigh enough to matter?

I looked online & found a bunch of different answers for how much a gallon of gas weighs...some say 6.5lbs some say 8lbs. So I have no idea if a full tank adds 78lbs or 96lbs to our car. Someone help Maybe ill start driving around w/ only 2 - 3 gallons @ a time haha....(unless im on a road trip of course)

Oh & if this is a repost..then oops

I believe density of gasoline changes depending on it's temperature. From what I read, the weight of gasoline at 72 degrees F is approximately 6.25 lbs per gallon.

So a little math: my GT has a 15.9 Gallon tank. If it is completely full, the weight of the fuel (at 72 degrees) will be approx. 99.375 lbs. Keep in mind, the colder the fuel is, the more dense it will become (thus heavier). The warmer the fule, the less dense (thus lighter).

Hope that's right. Anyone else have any ideas on the matter?

that sounds right

yeah but the question- is that when it's on E, or below E-cuz' when it's on E there is still 4 gallons left.

is that true, if so then i had no idea
