I thought i put diesel in this morning, apparently i didn't and filled it full of petrol instead.
As the vehicle started running poorly i made a detour and limped in to a mechanic's shop. They where able to help me straight away and was back on the road in a few hours.
I had always though my wife would be the one to stuff it up and put the wrong fuel in, but nope it had to be me.
I did give her a lecture about making sure to double check next time she fills up though:)
