I find this somewhat peculiar... I would expect the rate of fuel usage would mean the fuel is consumed faster than the fungal culture would grow... this is normal in commercial marine applications. Unless that is, the vessel was bunkered with what was already contaminated fuel ....?

There should also be scheduled fuel tank cleaning and inspections as part of routine maintenance. As far as mechanical engine damage goes, this is very unlikely and is usua
