You believe everything your buddy tells you??? After driving 20 miles..let alone 2,000 miles will hie oil be clean ( On a diesel rig) because a FILTER cannot"strain out" anything in his oil that is soluble (sp?) and of course in this case anything smaller than 3 micron. All he is doing is backing up in his own mind the cost, etc...of the bypass system he installed.

But it is entirely possible for a 100,000 mile oil change. VW has been using 30,000 mile oil change intervals in their European commercial diesels for quite some time now. Nothing special except VW's spec'ed full synthetic oil and VW spec'ed oil filters. The optic sensor in the oil pan of their non commercial engines tells you when to change it also. They actually specify:

"2 Years/30,000KM/18,000MILES (most commonly used in EU) Oil Sensors might adjust distance base on the driving style"

"1 Year/50,000KM/30,000MILES (Used for commercial Vehicles)"
