I've seen quite a few old Mercedes diesels (from the 80s) with stickers on the rear bumper that read "biodiesel powered." I take it as a sort of trend, and somewhat dismiss the bio part of it, mostly because...
1) Where does one even
get biodiesel fuel?
2) Relating to #1, one night outside of Bob's Big Boy, I watched some questionable looking characters pumping a vat of old french fry grease of its contents and driving away. I thought then, is this biofuel of some sort?
3) I'd hate to wreck a very capable Mercedes diesel with questionable fuel. In short, who regulates "biofuel?"
4) The caveat to my caution about this is the Mercedes 300 sedan and wagon themselves, which are nearly as available as Miatas out here; just a couple grand more. Personally, I think they're very cool cars.
I don't want to be ignorant of this subject, so I'm hoping for some enlightenment. But can a diesel Mercedes really run on biofuel/biodiesel? And where do you get this fuel in a city like Los Angeles? What about vegetable oil? Kerosene? Etc.
Thanks for the help and insight.
