The EU are proposing an end to olive oil dipping dishes in restaurants for our protection. We already have laws (in this country) that cover any harm that might be done by bad hygiene practice.
What we don’t seem to have is a law that prevents Cladosporium Resinae (diesel bug) cross contaminating fuel tanks. Is your supplier supplying you good fuel or contaminated fuel? Does he know? Does he care? Has his delivery nozzle been in a tank that is contaminated before you arrived? Does he care enough to clean his nozzle after each delivery? Can you check that the fuel you are given is bug free?
The simple answer is that all suppliers should be compelled to treat their supplies. Whether that be producers main suppliers or retailers is for the clever people to work out. It cost about thirteen pound to treat 2500 litres that’s less than half a penny a litre. Fuel tax could be reduced by half a penny a litre to ensure that suppliers do this cost free. It is easier (more accurate) to treat 2500 litres than it is to treat 10, 20, 30 or even 100 litres. The %age error is far smaller. As of yet it is not know if under-treatment is effective or if over treatment is in some way damaging to engines.
Rather than some boaters and some retailers treating their supplies it would make sense for all suppliers to treat their fuel. That way we know that all fuel tanks are treated properly and the possibility of cross contamination is reduced to an absolute minimum or even zero.
Why should all suppliers be required to treat their supplies and not boaters. Well boaters are a varied bunch of individuals who have their own Ideas about where they will spend their money. Some will, some won’t treat their tanks. No amount of legislation will make Joe Bloggs treat the fuel going into his tank if he doesn’t want to. To check that his tank had been treated before a fuel nozzle is put in his tank will be cost prohibitive. I rest my case.
