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

By adding weight to the gas tank you actually move the center of gravity lower and more toward the center of the car thus improving handling. I wouldn't know how to quantify the improvement but it could be significant given the added 100lbs.

lol i disagree , very first time i filled my prelude up (full tank) i lost the end on a corner i've taken(faster) thousands of times before and since , my only thought at the time was that the full tank had made the rear of the car heavier . Maybe not but it was the only thing different.
anywho
That was the end of that honda adventure !

Tire pressure, road/tire temperature, inexperience driving with full tank of gas. Could be anything. The physics of it are fairly simple though.

To illustrate this another way: My truck rear end slides around fairly easy if it's unloaded. When I put all my tools in it's almost impossible for the engine to spin the rear tires or cut loose in a corner.

lol i think i was just looking to blame something other than my driving
