I've been a diesel mechanic for all of about three months now since I purchased my boat. I've got a ton to learn but one thing that seems to be of great importance is feeding your engine quality diesel and the taking care of your overall fuel system. The previous owner was bullish on the use of Startron Diesel Enzyme Treatment at each fueling. Doing the research, I can't find any reason not to continue using it, and I did use it when I fueled the boat on the first (and only to this point) occasion. Reading through the product descriptions for Startron though I don't see any reference to it being an anti-microbial. Should I be adding an anti-microbial in addition to the Startron? On the one occasion I fueled up, I purportedly purchased, ValvTect Premium Diesel from the fuel dock I pulled up to. This diesel reportedly does have an anti-microbial in its mix.
I'm also curious how particular are you folks are with putting a particular diesel product into your fuel tank. My boat is currently in Puget Sound, are most of the marinas/fuel docks in a region selling effectively the same product? I think I understand that there can be a relatively large content difference in the ethanol levels of different blends but is that more regional of can that really vary from fuel dock to fuel dock.
I appreciate the replies! Note that the engines I'm running are older, Volvo Penta TAMD 40s with 3K- hours.
