Biodiesel and your new TDI.

[250 downunder]

I am progressively increasing the percentage of Bio in my MkV TDI. Up to 25% currently and it loves it. I make my own Bio and test every batch. I wash until I have neutral PH and dry until there is minimal water content. It is filtered through a 5 micron water block filter before it goes into the vehicle.
No problems to date and I don't expect any.
I also run an F250 [7.3L Turbo Diesel] on 100% Bio and the only problem to date has been with fuel hoses which I have now overcome. I have an exhaust gas temperature gauge on this vehicle and it definately runs cooler on Bio.
I shudder when I read about Bio being made by adding crushed "moth balls" to used vegetable oil. It is little wonder car manufacturers decline warranty when Bio has been used.

This is a gray area due to the wide variety of source materials used to make biodiesel, which means there are lots of undesirable finished products that could end up in your fuel tank. This kind of uncertainty can make FIE manufacturers toss and turn in their beds at night worrying about bad stuff roaming through their equipment such as:* Free methanol* Water* Free glycerine* Mono-, di-, and triglycerides* Free fatty acids* Solid particles* Oxidated fuel

all production issues none of which effect me as the bio comes str8 of the centrifuge as made by my hand.

Making biodiesel is really easy:
-Filter fryer oil with a calico bag
-Dissolve napthaline (crushed moth balls) into it
-Filter again
-QED

this sort of process gives bio a bad name

Dutch aussie and a few others make there own with no complication.

I would be interested to know there thoughts on your Bio recipe as I think its a
bit more complicated than that to make.

Have you actually tried this recipe.

Hi Guys,

I have now done 30,300 Km on home made Biodiesel and the Caddy is purring.
My book has been out for months now and is available from me or from Think Global.
You will find more information on my sites below.

After the report I read from Audi on biodiesel based on the transesterification process, I would never go near it in my own vehicles.
After the change to fuel lines and injextors and pump that my dad had to do from using home made biodiesel and straight run cooking oil (highly filtered) I would not use that in a car post 1995.
