Ok, I just spent the last 40 minutes looking over BITOG and it's quite interesting. I assume I was supposed to be looking at used oil analysis, which is mostly what I did. What concerns me, is the lack of consistency when the subjects changed oil. Way too many variables, changing back and forth between brands,viscosities, and base oil. (mineral based to synthetic and synthetic to mineral based). If there is a specific area or post, that you think I should see, please let me know. Again, not being a smart guy, just trying to learn what I can. From what I saw, some content #'s were high, some were low. OCI intervals also seemed inconsistent. Thanks, you've shown me another place to get lost on the internet.

vtmdsm25, If you're asking about changing the filter at 1000 and 3000 miles after changeover from conventional oil, I say if it makes you feel more comfortable, do it. The peace of mind is probably worth more than the $10 or so it will cost you for 2 oil filters. When I switch, I flush with the same oil I've been using ( Havoline 10w30 ) And then change to M1 10w30 with a new filter ( wix, my personal preference ) and go straight to 10,000 mile OCI's with a filter change every 5,000 miles. I'm not an expert, but it has worked for me more than a few times. Call me goofy, but I use the stuff in my tractor, roto tiller, and push mower too. NEVER a single oil related problem, I think that pretty much speaks for itself.
