I have run about 100 gallons of B100 through my '95 E300D (doesn't
take long for me) and was looking to compare numbers with others on
the list who are running B100. I gathered a fair amount of
performance and economy data before and after the switch and was a
little surprised by the outcome. Every source I've read on biodiesel
indicates that you should expect a slight decrease in power and
economy because there is slightly less energy in biodiesel. Well, I
have noticed no significant drop in performance as indicated by the
stopwatch. The butt dyno tells me that I'm a little down, but
barely. So, I was expecting about a 5% drop in power, and I would
guess that I am seeing less that 2%. What I have noticed, however,
is that my economy is down a little over 15%, from around 29.9 MPG to
25.3 MPG. To make sure it wasn't the car, I ran a few tanks of dino
fuel through and it again returned to around 29.9 MPG.
Is anyone else out there running B100 who is as anal as I am and
documented the changes? I'd love to compare notes.
Thanks,
J.B. Hebert
