I believe the problem that OP is alluding to is that in many parts of the country, most diesel pumps have stickers that say the fuel may contain "up to 20% biodiesel", which exceeds the 5% limit that MB stipulates. I, too, have been wondering how large a concern this is, and how commonly the 5% limit is exceeded in practice. Reliable information on this topic appears to be hard to find.
That's exactly what I was referring to. Several tanks in some of the local gas stations (in Houston) I have seen, contain the wording 5-20 %. They do not specify 5%. I never paid attention before, never needed to, I have a daily driver that is gas. Now, I am beginning to look and research. Its a little disconcerting to see how many are starting to use that wording, especially with MB strictly sticking to the 5%. How do we know?
