I copped a bad batch of fuel from a nearby servo a few months back.
The servos unleaded tank copped a couple of thousand litres of diesel by accident.
Even though they new, they just added more unleaded and didnt get it pumped out and sent back to the refinery. It was sold through the pumps over the weekend making cars hard to start and run rough.
I spent a day chasing a supposed electrical fault on the Ratmobile.
