by-pass filtration does WONDERS and I'm not sure it matters who's "kit" you use, or make your own. It's a "technology" that filtered down from the long-haul industry as is running centrifuges on engines. Now the filter makers are kind of combining two filters into one, a by-pass set-up so to speak.
No this isn't necessary. People are watching that idiot on the internet and now this "draining the HPOP" is all over the forums. It is a good way to get air into your HPO system and these things can be a real pain to burp that air out of!!!
Extended Oil runs needs to be done right, and if done right, I don't see a big advantage over reg changes. For a bypass system the single Amsoil is okay but filters are way to expensive, the FS2500 is way over priced, but somebody has to pay for their 6 pages of hype in every diesel mag on the planet, the oilguard single bypass is probably one of the best reasonably priced systems out there. In order to run extended service UOA's are critical, so you know how your oil is doing, the full flow still has to be changed at regular intervals. So buy the time you figure the cost of all this in there really isn't much savings to be had. The dyno oils of today are far supperior to lubricants 20 years ago, and changing the oil and filters at regular intervals is key to prolonging the life of your engine and powertrain. I am going to add a single bypass system to my truck, not for extended service though, I will still continue my 5K intervals, every UOA I have done ( every third oil change) they all tell me to go 7500 on the next sample, but I prefer being safe than sorry. So add up the cost yourself, only you can say if extended oil service is good for you.
