from talking with the marina operators it appears to be a myth about diesel quality / grades IMHO- the marinas seem to use much the same suppliers, who, can only get the stuff from 2 or 3 refiners. So it comes down to storage of the stuff and how fresh it is - see my post on diesel chemistry - research show that 28 days after refining the diesel has lost about 1/4 of its quality. So if it's hanging around in tanks for 3 months before you use it there is a greater chance of it not being as good as an operator who gets a delivery each week. And as for price well volume = discounts hence cheaper prices - as we have been offered.
