Diesel additive

[tckearney]

Hi All   I have recently been reading about the dreaded Diesel bug.  I have been using the expensive diesel biocide treatment every time I fill up and even over dosing.  Recently a very experienced Engineer who has worked on large diesels all his life, told me that TCP works just as well and causes no damage.  Any Comments.

Hi....what is TCP ?

If you believe him, stop buying biocide.  But I'll keep using Marine 16 and Grotamar alternately, every time I fill up.

how much TCP would one use? A bottle-full?

The composition [of TCP] is:
phenol   0.175% w/v
halogenated phenols   0.68% w/v

Presumably the rest is water, just what you need in a diesel tsnk.

I much prefer enzyme based treatments rather than raw chemicals. It is surprising what harsh chemicals some bugs can tolerate, but the enzyme treatments are very targeted. I have had good results with Soltron.
