An update
2010 2L Duratec Focus LVII auto - 68,700kms
M1 EP 0W20 - 4yrs/17,808km
Driving Conditions: All city driving
Zero oil added over the 4yrs, stayed right on the full mark.
I live overseas from the car. Last oil change was 2018 with an original planned OCI of 2yrs. Due to travel restrictions in 2020-2022 I was unable to get back to do maintenance on the car. Luckily using a high reserve oil was able to extend safely past the usual milage and keep it going.
As the oil did reasonable mileage I flushed motor with spare oil I had on hand. Drained the oil, drained the old filter, reinstalled the old filter. Filled up with some new but old oil (Val Durablend). Ran the car for a few minutes as varying revs. Shut it down, drained the oil, removed the filter.
New prefilled oil filter installed.
Refilled with: Mobil 1 EP 0W20
Filter: M1-102 change
Schedule OCI: 2yrs
Before oil change:
New M1 after startup.
