Can anyone offer any advise regarding the use of fuel additives with Bio. I have always used an Aussie made treatment called Diesel Power. In over 15 years of use in marine and road applications I have never had a single problem with any type of fuel contamination - in fact in 12 years with my current boat I have never drained a single drop of water from my filter/separators and it has alloy fuel tanks that I rarely keep full, normally this would be a recipe for condensation and water contamination. I would love to use it with my Bio. The manufacturer says "Suck it and see".
