with respect to a delivery driver changing fuels between deliveries I knwo that what they do is change over fuels about 100lt (from memory) before the end of delivery. They then have a fuel line full of the correct fuel for the next delivery. This is what the delivery driver did at my house.
I do wonder what he does if you are the first delivery of the day?
