How long is a piece of string ?
Questions answered with a question is a defensive move. lame too.
No its not... It was something for the OP to think about than anything... Basically like you guys have pointed out, there's loads of variables that need to be considered. Its not a simple question to answer unless all the info is there on the plate.
Rich777; the member is a new one by the looks of it, maybe or maybe not, either way first impressions are not well received from a new member or even an older one like me when I take time out to read your reply...its easy to just say nothing rather than waste every ones time. Take the high road and offer some good feedback to a seemingly easy question no matter how easy it is or not to answer...or nothing buddy.
...not everyone is an expert such as yourself out the gate, not even yourself. you also at one time asked some lame questions I am sure.
£50 In mine gets 380-400 miles, change your engine/gearbox oil may help. I use Motul 8100 Xcess 5W-40. Does it get to temp quickly, around 1/2-1 mile journey? adjust your valve clearance?
