Dont stop until it sounds expensive
I believe its roughly 9 lbs per gallon, so a full tank at 234 lbs and the driver can definitely cause the drivers side to sag more than the passenger side. The thing is, if you replace one rear spring it will probably make it higher on the drivers side. Maybe a mild add-a-leaf is in order?
you are close sir i think gasoline weighs 6.8 pounds per gallon
