I just heard a commercial featuring a choir singing, “VW Passat EcoFuel only emits 20 grams of CO2 per kilometer… 20 grams per kilometer”, and wanted to comment!
I think the times have changed. 
Or put (perhaps) more succinctly by Joe P. Ickuptruck, “What kinda s**t are they letting on the radio nowadays??”
Regardless of mine or anyone’s opinion on biogas, this was on Swedish radio, just now. I love it!
