It's not hard to get the timing right.  I've done it with a 4" tall, 16" long tool box of tools, on the side of the road.  If I were anywhere close I'd do it for you in a half hour or less but...

Subject: [Vwdiesel] Biodiesel MPG?


On 11/13, I  drove from Nevada City, CA down to Carlsbad, CA (just north of San 
iego) with my Mercedes E300 diesel to attend an antique radio swap meet. In 
acramento, I tanked up with B-20 biodiesel, I refilled with regular diesel at 
razier Park, atop the Grapevine & averaged 25 MPG. I then drove thru LA to 
arlsbad using the A/C as it was up to 93F in LA. On Sat., 11/16/ I left 
arlsbad & refilled at the top of the Grapevine & averaged 34 MPG. Then from the 
rapevine to Sacramento where I could refill with B-20 biodiesel, I averaged 36 
PG! No A/C used on the return trip. I always thought you could get the same MPG 
ith biodiesel as with regular ULSD diesel but now I am wondering. I am sure 
ome of you have been running biodiesel from B-5 to B-100. What has been your 
xperience with MPG when running ULSD to biodiesel. 
 have been using  the B-20 biodiesel as I feel it provides better lubrication 
or the injection pump & I understand B-5 is mandated in all diesel in Europe 
or environmental & balance of payment reasons. Am I correct? 
For those of you who have been wondering, I have not worked on my 1982 VW 
uantum TD since I got my Mercedes E300 a year & a half ago, but have not given 
p on it. I feel I need to find someone in the Sacramento area who really knows 
ow to get the timing right on VW diesels. The independent Mercedes mechanic I 
ave found is reasonable & really knows his stuff but will only work on Mercedes 
ars. I have not had any trouble with my E300 since he corrected the check 
ngine light with the help of his $20,000 Mercedes engine code reader. The 
ormal OBD 2 code reader from 1996 on is useless on a Mercedes. I have become so 
acklogged on my email that I have been unable to read all the recent postings 
rom this VW diesel discussion group.
