On the way to today's weekly Sydney learner session, I was almost at zero fuel in the main tank, so filled up at a big Caltex on Parramatta Road. A few k's later, the motor cut out in traffic. Pulled off, but couldn't restart. Battery was cranking okay, so I assume that either I got a batch of bad fuel (surely that's unlikely at a major servo), or it's because I ran the tank down almost to empty. So I resolved ... never let the needle touch 'E' again before I fill up. But ... I just noticed that in this thread PatB says that: So ... what to do?
