does anyone know what size gas tank our cars have and how much does a full tank of gas weight?

 

I know water is 8 pounds per gallon,something like that. Our cars hold what,15.5 gallons of gasoline? I'm not sure how much less/more gas weighs compared to water,but I would say a full tank of gas weighs in ths area of 125 pounds or so if gas weighs as much as water.

I tried to help

 

hes close enough, I wont call him on it .
