I know this has been done to death but my symptoms aren't quite the same as I've read in MB&Y although still have to receive March edition which had the article I've been waiting for. Symptoms, fuel full of sludge, engine smokes WHITE smoke and coughs and lacks power. Pre filter full of sludge after an hour (new filter). Fuel taken from filter in to jar and allowed to settle. stays black and the sludge partially separates.
Fuel has been treated (stupidly can't remember if biocides or enzyme, bought from local motor store starting with H and ending in alfords) so I assume the bug is dead. Fuel maybe still has water in it? Looking at the fixes in April MB&Y it was a little inconclusive or I have vital parts of the jigsaw missing. Don't know if I should have the fuel polished or just run it until nearly empty and then fill it up with decent fuel and put preventative treatment in. Unfortunately the cost of the fuel polish (about 100 gallons left in each tank) will buy me a reasonable amount of clean fresh diesel. I suspect the answer will be the polish and then save up the couple of grand to fill the two tanks but hoping there may be a better answer.
Have spoken to two marine engineers, one recommends fuel polish (and funnily enough he can do it for me) and the other reckons a waste of time (and he can't do it). Thoughts?
