Sounds like with a bypass filter you can really extend your oil change intervals:

By-Pass Oil Filtration

Quote:
How long can an oil fill be run using by-pass filtration? We've heard claims of large (Class 8) diesels going 1,000,000 miles on the same fill of oil with no harm done to the engines. We have analyzed oils which have been in service 240,000 miles and found nothing unusual in the analysis, other than higher than average iron and lead (from steel parts and bearings), and these wear accumulations were not intolerably high.

After having run many tens of thousands of diesel engine oil samples, it is our opinion that a by-pass oil filtration system is one of the most important factors in extending oil drains. If you are interested in extended oil drains, we suggest you investigate adding this type of system to your engine.
