The basic point of having a DIESEL ONLY sticker next to the fuel filler is to tell people to not to try to put gasoline into a diesel bus. So tacking on the word “green” in front seems to be more of a marketing effort:
What if one put some of the other seemingly infinite types of diesel into this rider – what would happen?
Nothing, I’ll bet.
Reminds me of the phrase “clean coal.”
