e.g. Mobil1 5w40 and BD28, used for a year for 3K km: When to change the filter, when to change the oil?
If you don't reach 5,000 kms per year, then change oil and filter once a year. Since you are using Mobil 1 fully synthetic once a year (provided you dont reach the mileage requirement of 10,000 kms) that's about right.
