hi Brian!
i agree that a higher-mileage recommendation would be more useful,
but BioD use hasn't been wide-spread enough for long enough yet that
there's a lot of high-mileage experience to point to. even though we're
well into the millions of miles of use in the local fleet here, we're
still kinda' on the frontier here in the high-mileage regard as it
relates to what we think of as high-mileage for our MBZs.
as for the reason people seem to feel the need to mention that they
haven't had any problems, i think it's in part because of all the
misinformation that's out there about BioD use, as well as all of our
natural suspicions. for example, you often hear about needing to change
fuel hoses when using BioD, but i think that concern's seriously
overblown; i'm still waiting to see any evidence of any need to do that
on my 300D after several years of almost exclusively B99-B100 use.
cheers!
