I'll soon start using biodiesel in my 85 190D and wanted to see if anyone here has done the same? Are the rubber parts synthetic by this year or do I need to plan on changing them? If so, what do I need to change? I'm assuming fuel supply and return lines and injector hoses? Anything else? Gaskets?
In the future, I plan on converting it to use WVO. Any ideas about potential problems with this particular vehicle?
