If I have been pootling along in top at 50mph in traffic on an A road, then suddenly change down and accelerate hard to overtake it will most probably happen and if it is below 10C then it will certainly happen
Yes that does happen.
I am careful about fuel and only use my preferred ( i.e. they are always nice to me) petrol station.

So is the consensus that I shouldn't look elsewhere ? And what about the fact that I used an extender and everything was better ? Am I storing up trouble?
Thanks for all the replies.
