Slightly odd question but what happens to the £80 petrol you filled up with? Can this be syphoned (sp) out and put in a petrol car or because it has mixed with diesel in your fuel tank does it need to be disposed of?
Have you tried AA/RAC/Greenflag. Heard an advert this week that one of them (can't remember which) offered free mis fuel call outs
