Re: Diesel Fuel Treatment: Multiple Questions
If it helps, my Yanmar JH series operation manual, under Additional Technical Fuel Requirements, states, "Do not use biocide".
If that is one of their CR Diesels, perhaps they have additional filtering requirements and the very close tolerances have some difficulty with the chemicals in a biocide. Maybe. Perhaps.
OTOH.... I have not heard of such a demand..... so, it's a puzzle.
