How much a full tank of gas weight? Every time filling full tank of gas, my car drive better. I am not sure how to describe it but I just feel like it more, like to gun it. I feel it's more stable. Is it the pressure increase make the car run better? Or is it the weight in the front make the car more stable? Do you guys feel the same or it is just my imagination after spending the $$ feeding the car?
My car is very lowed and harsh.
