seriously..high TBN #s and virtually NO wear???!!! But I did notice that the highest iron counts were with Amsoil. I wonder if that's break in or "not so good" protection?

What's really interesting is the difference in the two labs that analyzed the run on Amsoil. Those numbers are quite a bit different, especially with Copper.

If you want to do these short changes why not drop the UOA's and/or the bypass. You could safely do an occasional UOA for trending with or without the bypass. Since its already installed I would leave the bypass on and cut back on UOA's. Or you could always start doing longer OCI

Thanks for the suggestions but I confess .. I'm afflicted with compulsive oil change disorder or COCD.. Despite being fully informed on the longer life characteristics of today's engine oils and the benefits of bypass filtration, I can't help my self .. I just like to change oil .. cost, time, ect, are irrelevant to me .. I also get a kick out of doing the UOA's and seeing the low wear numbers.

Isn't it freeing to sharing in group. Step #2 you have to sit down and tell your freinds and family about your problem and ask for forgiveness. The long walks searching the isles at walmart just to find you staring at jugs of oil. The needless trips to the parts store looking for 50 cents off a case. Driving to parts of town you have no reason being in just looking to score some Delo or PP. We all know what its like.

I have the same affliction. Comparing oil specs on a spreadsheet. Calculating oil costs on a spreadsheet. Considering trying xyz oil (Mobil, Shell, Redline, Amsoil) next time just to see how it does. Changing my oil every 10K miles even though OA shows it's just fine.

Mr. Plock, you score high marks for honesty and conceptual understanding, because you realize that your wants outweigh your needs. Kudos to you. I disagree with your operating methods, but cannot argue with your decision; you obviously recognize your BITOG affliction, and I applaud your conviction. Can't say that some of us aren't "bent" in our views as well. Some, such as myself, have WAY more oil in the garage than we could ever use in a year's time ...

You know, you can always use a sampling pump to do a UOA for $25 and send the other $50 you'd spend on an unnecessary oil change to me instead.
