hi, i've been reading the various posts on various forums about running biodiesel in a mercedes diesel, this is the most recent post i could find, as most are a few years old, so i'm wondering if any of the info has changed.

are the regular rubber hoses fine for biodiesel?
even the ones that get heated?

what if you're only running B99 say... 1 week a month, out of 4 total fills per month?

i feel the original poster's Q wasn't really addressed.

thanks.
