Well, managed a tank of 95 RON weasel pee from Morrisons on the way home from work. Got home, dodging the bits of the map where there's pinking, drained it into my government approved
20L jerry can and went to the local garage and filled it again with Super Unleaded.
Garage had one normal unleaded pump, a couple of super, and no diseasel.
There were almost fisticuffs over the 95 RON pump. Nobody wanted to pay the extra few pennies for the super, so I drove straight up there and brimmed it.
Now, imagine you drive a tractor. You're on vapour. No local garages have diseasel any more. You pull into one and find the diseasel pumps closed. Do you:
1) Nurse it gently on to the next petrol station. Maybe they'll have some.
2) Flail around the forecourt shouting obscenities for 30 seconds before betting back in your L200 Warrior (W**ker, more like) and tear off in a cloud of black smoke, leaving 20,000 miles worth of rubber on the forecourt and nearly flattening another customer as they walk out of the shop.
It's a tough one, I'll grant you that.
