Sorry if this turns out to be just another oil thread. But ...
I just did another oil change on my new 2010 left-over Griso 8V I just bought 6 months ago in Dec.
The first 900 miles had whatever oils the factory or dealer installed,
between 900 and 4,500 miles I used AGIP's 10w60,
between 4,500 and 8,000 miles I again used AGIP's 10w60
between 8,000 and 11,000 it had a mixture of AGIP's 10w60 and Motul's 7100 10w60,
and this past mileage from 11,000 to 14,500 miles it exclusively had Motul's 7100 10w60.
And with each oil change; I also changed the gearbox and CARC oils.
Each time using AGIP's 85w90 and 80w90 respectively.
With this last oil change I noticed that the motor drain plug was nearly completely free of any metal debris, the CARC's drain plug had less than usual, and the gearbox's drain plug still had the same amount of metal debris as all the previous oil changes.
Is it possible the lack of debris on the motor's drain plug was the result of switching to Motul ?
Is the motor just starting to get fully broken in and the oil switch made no difference ?
(And the gearbox and CARC are still in process of being broken in ?)
Or it's neither of those; instead it's something else.
