* rego_nono there is nothing to be scared of running your oil 10000km with a Baldwin filter this is what they are designed for, And if your vehicle is a sluge monster it's because your not using good oil that has a good amount of calcium in it which is the cleaning agent in oil. If your car is sludge you should use diesel oil it's high detergent content will clean your engine out and restore it without using a engine flush which can send big clumps of slug to clog up oil passageways.

Oil analysis testing proves this oil change interval is perfectly fine with quality oil especially oil with a high TBN like the oils I have mention on this thread. SN oil I would not run 10000klm they don't have enough additives in them.

This is a very good site to see how much additives are in the different API rated oils are and also why you should avoid unknown off brand oils you never know what is or is not in them.
