Done about 5,000 mainly local miles with it in since May (I think). Quite a lot of hard driving as well though and had to top up about 1 1/2 litres during this time. Spark plugs are almost brand new, valve clearances perfect (done them all a few months ago - monster tutorial is on here ), Air Filter replaced on Friday just there, throttle body cleaned, EGR plate cleaned, fuel and injector treatments done, fuel filter changed about a month ago, always Super Unleaded from Shell, once with Esso and now always BP. No vacuum leaks present. No fault codes. Can't think of anything else! lol I'm not saying performance isn't good, it is but not quite what it was. Feels kind of slow on the uptake even when starting at 4,500rpm. Something is different, I can feel it.
