Congratulations on your MB purchase and welcome to the forum.
You will find TONS of help here on everything for maintaining and repairing your vehicle. While there is some discussion about alternative fuels here, you won't get much love on this forum talking about it. This is the best MB forum out there and it's populated by owners who love MB's and want to protect them ALL from harm.
Research THOROUGHLY before you do anything. Here is a site that will provide all the info and help you need to make your alternative fuel choices.
