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
Well you're getting about 13.5 MPG with that information. As best I've seen so far CNG will often get 2-4 MPG below the gas number. (I looked on fueleconomy.gov and went year by year under car type and looked at bi-fuel).

The nearest station to me was at $2.10/gallon.

So going with 9-11 mpg at $2.10/gallon you will go, 230 miles to 286 miles. Cost will be about $55 to fill 26 "gallons".

To do 350 miles, $66.81 to $81.60.

So your savings would be, ~$50/tank. So for this to pay itself off (at $5k investment)you'd have to do 100 tanks worth or 35,000 miles. Given the average per year is like 15-17k...about 2-3 years.
