I've been using Biobor JF, which could be 10+ years old (came from PO with the boat), at the maintenance dosage. I'm going to get a fresh bottle and up the dosage to "shock" level.
I've also been using Opti-Lube XPD for its lubricity properties. It is not a biocide, although it does have a de
mulsifier as I mentioned in my prior post.
I used to use Star Brite EZ Stor EZ start detergent additive, but discontinued it when I started using Opti-Lube with the demulsifier because of the old Steven Wright joke:
For my birthday I got a humidifier and a de-humidifier... I put them in the same room and let them fight it out.
I would like to add the Star Brite Biodiesel to my cocktail, but can't find it. Hence my prior question to
An important part of the whole anti-slime question is fuel management - the old "full vs. empty" question. What I have been doing the past few years is to fill up the tank before winter to avoid condensation, then consume as much as I can during the season before filling up completely again. I have never seen a drop of water in my Racor, so that's a good sign. But I am still seeing some bacterial growth which requires me to replace my Racor annually. I'd like to do better than that, so I'm willing to try something different.
Do any of you continuously top off throughout the season to keep your tank full all the time? That would avoid any head space and minimize sloshing around. Would that reduce biological growth? I'm not sure. I do know that since I consume about a tank every year, the back-mixing that results from continually topping off would mean the fuel would have an average age of 2.7 years. That's why I try to run down my tank throughout the sailing season, so I'm not dumping new fuel on top of old fuel.
