Thanks to all who replied, I didnt go through that sequence for PM so will try again thanks, no conection between Chain and MPG obviously, just haveing a double moan really, the Vectra is the youngest car I have by 12 and 22 years respectivly but the one that costs the most to run and that worries me the most, that said its doing a great job for us at the moment and has been a godsend this year. After a weeks commuting with the wife is got 500 miles to do this weekend so maybe I'm going to prove all the reviews wrong.
