[C320-list] Engine/Fuel Issue with my 2001 Yanmar

[Karl Mielenhausen]

Harvey recommended Biobor as your algaecide. He had no preference for
lubricity enhancer. (I happen to use FPPF Killem).

I am currently adding Diesel Kleen for lubricity...

One of our other owners uses this one...

which has the benefit of working at lower ambient temperatures.

Both are available at WalMart and auto stores.

I have also used AFC-705 in the past

It has the benefit of algaecide plus fuel enhancer.
Could not find it locally, however it is available a big truckstops and
mailorder (e.g. Defender).

Looking at the literature on Biobor JF, it looks like it might serve both
functions also....
