the question STILL is not answered: How far will $10 of NG take me compared to $10 gasoline.

Simple question that seems to have no answer

$10 of NG will take you a little more than half as far.

I don’t normally post but I’m looking at a Ford truck which can be converted to a bi-fuel (runs on gas or CNG) and has a 22 gallon CNG tank in the bed.

Looking at the following estimates:

Gasoline mileage: 13 city – 18 hwy
CNG: 11 city – 15 hwy
Currently 86 octane gasoline in my area was at $3.45 yesterday and CNG was $1.14 gge. (CNG in OK is cheap right now. Gallon Gas Equivalent = gge)

City Gas mileage:
$10/$3.45 = 2.8985 gallons
2.8985 gallons x 13 mpg = 37.68 miles

City CNG mileage: $10/$1.14 = 8.7719 gge
8.7719 x 11 mpg = 96.491 miles

Does my math check?
