What is the running in policy ?
When I had my Clio 182 I did a fair bit of reading up and the consensus was to ignore the manufacturers running in policy.
The new theory was to cane it for first 500 miles taking car on short and hard accelerating trips followed by a cooling period and then repeated. Apparently this enables the pistons to 'bed in'.
Then after 1000 miles change the engine oil.
I did this with my 182 and after a few thousand miles it was flying and never used any oil.
Sold it to a race track in the end for performance track days.
