[Vwdiesel] Newbie questions re Stanadyne

[Andrew Buc]

Now that I've had my '84 B2 Quantum TD for 3 days, naturally I have 
some questions.

I got a bottle of Stanadyne Performance Formula All Season Diesel Fuel 
Conditioner from the garage that has been servicing my Audi 4kq and did 
the pre-purchase inspection on the QTD. This is the stuff, right? It 
says to lower the pour point to 40°F, use a bottle (16 oz.) per 60 
gallons of fuel. Since the bottle is marked in 4-oz. increments and the 
QTD has a 16-gal fuel tank, I think this is going to work out to 1/4 
bottle per tank in my case.

Do you folks agree that this is the right dosage? Should I be using it 
religiously with every tank of fuel? I don't know that lowering the 
pour point is so important right now with spring on the way, but I 
gather that the following are issues with diesel: 1) water; 2) 
bacteria; 3) lubrication--low-sulfur diesel is mandated in the Seattle 
area, where I live. Does the Stanadyne cover all the bases? Should I 
use it with biodiesel? I plan to try and run B99 whenever possible, but 
I may not always be able to, especially in winter.

The bottle cost me $16, BTW. I was eager to get some, and they had it. 
Can I get it significantly cheaper, and if so, where might I look?

Thanks!
