Best filter for this application

[sbc350gearhead]

Yes, but if the oil is not protecting your engine (for whatever reason), and the bypass filter is catching the tell-tale metal particles, then how would you know? Would it be better to "dial in" the proper oil choice, and then install a bypass filter?

Good point, but the bypass cannot catch all the sub micron particles. They have an efficiency, so believe me you will get about a 99.9% accurate analysis. Also your Nit. Oxy and insolubles, TBN etc. would be the best indication of the oil condition. It can be clean but still have problems as you indicate. Now for the real eye opener, this is where you need Terry Dyson to interpret your analysis. His keen eye and analytical mind plus his interpative skills will detect ANY problem. No I don't work for him either, I am a paying customer of his.

Look at it this way, with or without a bypass filter you normally don't read the big chunks, 20-30 micron or larger. Remember many, many OTR trucks that employ bypass filters have no problem with analysis, it is really a non-factor.

What is the average micron size of a particle tested in a UOA?

To determine this you would need a particle count. So a partial answer would be anything less than 30 micron to the smallest particle, depending on what the filtration removed. One thing to visualize is if you have a 30 micron particle of copper removed by filtration, you will more than likely have a smaller one still in suspension in the oil also, and that one is read by spectrographic analysis. So it is a wash. This is not a scientific view, but generalized.

Bob and Vetteman, I understand the idea behind the by-pass filters and the benefits they can provide in some situations... However as Bob stated that he doesn't want me cutting and pasting the USENET content I will not. I will say however, that the questions raised by the USENET posters were the exact same questions I had when I first ran across Ralph's posts on USENET which he never answered. I'm not going to spend half an hour paraphrasing and re-phrasing in my own words the same questions that were asked of Ralph many times on USENET and which were never answered.

I will say that some of his claims were specious at best and some proven to be essentially outright lies such as letters he posted that he claimed came from a certain person within the North Carolina DOT about how they were using the type of filters he sells on many pieces of their equipment and listed their name and title. The person in question and position did not exist.

If anyone doesn't believe me, they only need to look for themselves on Google Groups.

I won't bother asking him any questions because he most likely would respond in the same manner he did on USENET... which was simply by ignoring questions related to the filters and his claims that "oil doesn't wear out" including the additive package.

You'll still know, but to what degree I donno.
This is a question I'd like to have an understanding about.
I've had bypass filters on before, and to my applications it seems that you get 2-3 times the miles per oilchange, with the same test result levels, i.e. si-18 or whatever. My experience.
Question is What additives or traits to the oil that do not show up on the tests are there that we need to look at?
I donno the number, but I think there is a formula to figure out when and HOW much oil
to remove from the system to provide maximum
$$$ (ROI), without hurting your engine. Got to be
a way to figure it out for sure. I think I do a fair to good job on my own, but I'd like to have tech data to back me up.

Forkman,
The state of North Carolina does many tests on products. They did a test on school buses using Amsoil bypass and one other brand that slips my memory. They did an install on their ferry boat fleet using the GCF.
I have been familiar with bypass filters for over 30 years, and I can tell you that Ralph Woods is one of the most honest gentleman in the business and has a very good reputation. I do not know him personally, but do know a few people that know him.
I do know some people that I do not like or like their information on the internet. I really try not to let my views be known concerning them. Their opinion is as important as mine, and in most cases probably better.
An interesting item to show that info is available, however not all comrehensive, type in these words in google:
