Has there been a change to your scheduled maintence plan or procedures like oil changes or cleaning of the 6/7 bearing strut?
Normally coking doesn't just "appear" across the fleet unless something has changed.
As an FYI: generation III oils are better and an external filter highly recommended which can also allow you to extend your oil changes if you so wish.
