Why is is that a fuel that was originally for agricultural use and marine engines being defended so well by the marine industries customers?

I think its because, you've been getting away with using it for personal use for so long, you'd rather not have to pay the extra.

I have a diesal land rover, so why I can't I use red d in it?? You can use it for your boats for personal use, why not a car??

Pink petrol!! Thats the way around it. I just think the whole ordeal has been blown out of proportion.

IMHO, of course.
