To make it easier to calculate.. this is what i need to know ( to convince my wife)

Filling up the tank 26 gallons @ 4.4$ is about 120$
And it will go about 350 miles

How much would i have to pay for NatGas to go 350 miles ?


one more thing i remember.. the smell of gas from cheap installations God it smells like gas in the garage, interior of the car, under the hood. Equivalent of a poorly maintained diesel engine, but add the smell
