I have to agree with XS650
Ralph you and I have "tangled" in ideology land before on this topic and I am aware of course that you market these products
I would never place a new heavy truck in service in my fleet without a centrifuge type by-pass filter attached and running a premium synthetic oil because the engine must do about 650k miles without major mechanical work in its life for me. I am a realist and for me the costs must not exceed the benefit - simple as that
Heyjay ( Jerry ) feels the same way I believe
As an example we do not use extended life fuel filters that Detroit Diesel recommend changing at 100k. We use the normal filters and change them at 50k - about twice the recommended interval - the simple economics have determined this! We have never lost an injector!!!
I was brought up with heavy dozers, scrapers and loaders - Caterpillar, Allis, IH, - operating in a very hard/harsh operating environment. High up in The Southern Alps in New Zealand! Every piece of equipment used a cartridge type Luberfiner bypass filter. It served as a cooler and filter holding about 20ltrs of oil. This prolonged oil life and saved the problem of oil disposal in a very sensitive environment
In trucking there and here in Australia the standard into the 1980s was the Luberfiner. However, the technolgy has moved on and a centrifuge simply does the job better. I have tens of thousands of hours ( millions of miles ) of experience as a user to support this
This does not mean that in some cases and not only for "fun", the products you sell are not worthwhile
If I had an expensive classic car or a heavy marine motor ( petrol or diesel ) I would consider a product from your inventory. They do have an application especially on engines that have a marginal oil capacity and/or where placement of the by-pass filter in the cooling air flow enables it to act as an oil cooler too
But for 73Duster who started this thread, my comments echo an honest appraisal of his situation from my experience and using my knowledge
I have never run a car longer than 100k miles or about two years, ( well except my BMW and Porsche ) I simply turn them over to maintain the overall reliability I need when travelling in the remote parts of this harsh land where I live
Regards
Doug
