Disclaimer - I am not giving advice simply sharing some info and data I have collected during ownership of my Focus.
2010 2L Duratec Focus LVII auto
Summary – Some info not on this report but on previous reports
----------------------------------------------------
Notes:
None of the oils used are the recommended viscosity or ford spec.
*1 – I was unsure if the oil would have the TBN to go 15K kms so I swapped out 1L to bump up the reserve.
This Fuchs oil is fairly exotic – Zinc free and the old formula had no moly, 2 typical anti-wear additives.
I swapped over to M1 due to uncertain availability of Fuchs and I had an issue with long standing oil separating.
I now use M1 EP 0W20 in the Duratec Focus, K24 CR-V and the Miami XR8 Sprint
From these samples both MC and M1 filters kept particle size low.
In my samples I've done for all my other cars, time on oil has had no adverse impact on oil condition.
