thanks guys - I understand how you might have though me a little dumb!
I was looking for errors - and found them - I.e. 4.3 L is correct oil for PETROL 2l engine.
I do have tdci desil - so 6 L is correct.
HOWEVER! Yes I do know how to check oil level. ( well I think I do - been doing it for 30+ years in all kinds of cars... )
1st check was done with car having stood for over an hour on perfectly level ground. Took dipstick out and saw level off the scale ( above plastic end with level indicator on ) cleand stick - reinserted - with same result.
HOWEVER - and this is where it gets weird.... - I have done a number of checks since and level has fluctuated!! - sometimes well over the top of the max indicator - sometimes 2/3rds up the level - again all checks taken on level ground with engine stood for at least 1 min - up to 12 hours...
so - is engine retaining oil somewhere sometime - or is dip stick tube holding oil and confusing me!!??
Car has done 3,000 miles since possible overfill - if damage was done - wouldn't it have shown up by now - performance is good - MPG is 47+ and climbing ( driving quite gently most of the time as fear major damage ( Bearings / piston rings ?? ))
