Sorry to be a bore but do you have a used oil analysis of a similar car using Fuchs oil and Halfords oil and that showing less FE in the wear metals when the Fuchs was used and that would have to be after a few oil changes as for the first two changes you will be flushing out the newness of the engine which will be showing extra Fe in those first few changes.

In my experiance of checking used oil analysis this has not proved to be the case when only changing an oil for another in an engine that is run in .

I would be delighted to see the evidence of what seems like a factual comment on your part.

Sorry but when I challenged Opie Oils' guys about a similar comment when they said Fuchs would be better they could not provide quantitative evidence to back up their similar claim.
