Dear All,
Please find below the results of the latest oil analyses for my BMW.
The comments of the engineer performing the analyses were as follows:
Code:
The values of wear metals have risen only slightly. This low wear is within the normal range.
The values of additives differ from the values of the fresh oil reference in our database.
The fuel content is negligible and is below the detection limit.
I assume that the reason for the difference in the additivation of the used and the reference oil is due to the Wynn's additive I used?
