Oil bypass filters

Anyone used or have experience with oil bypass remote filter systems like the Amsoil one? Claims include only having to change oil every 160,000km, longer engine life etc. Most that I've read agree that oil changes can definitely be extended and thus offers significantly reduced maintenance costs, but that frequent sampling of oil for lab testing is required.
Any Actual experience out there?

i wouldnt bother, oils and their additives break down and get contaminated by stuff you cant filter out ,even though your oils cleaned, standard set up and regular oil changes works fine
