CNG isn't a big topic of discusion on the forums. But I wanted to see if those who have gone the "green" route, probably for business reasons, shared my thoughts on GM's 6.0L HD bi-fuel trucks. I did a full road test on a 2015 Crew Cab 4x4 a couple weeks ago and was disappointed in both the range and power of CNG compared to E-10 gasoline. GM loses 60hp and about 20% mpg with the CNG switch. Ford's CNG bi-fuel models don't lose either power or mpg. It was also somewhat surprising to see the 17-gallon (GGE) fuel tank really only provides about 13 GGE of fuel before it switches to gasoline.
