Default Help understanding my oil analysis with Mobil 1..

Got a 06 SG...stage 1 air cleaner, Rineharts, SERT. Bike had break in oil till 700 miles.. then changed to Mobil One 20/50 Vtwin in engine, Mobil 75/90 in trans and Formula Plus in Primary... Changed again at around 2500 or before.... then changed all again at 4622 before my Knoxville rally trip. I change it often and early I know....lol Anyways, for the fun of it I had Blackstone do an oil analysis on it.. What do you guys think about the wear and what about the viscosity?? Anyone want to decode some of this or give me your thoughts? Thought it might be interesting to look at and monitor.... Heres a link to the file. Thanks

I don't see anything to be concerned about in this. They pretty much told you that in their description.

With your permission, I'd like to use the numbers from this UOA and stick them in the top section.

You're changing your oil way too soon. Here's proof that the oil still has plenty of life left in it, and you throw it away. But, whatever helps you sleep at night.

The silicone is a little high. They said it should come down in the next sample. From what I read on the Blackstone site and BITOG site, silicone comes from air contaminants (sand). Why would that go down in the next sample? What kind of air filter are you using?

I notice there's a lot of zinc in there, compared to the universal averages. That's a good thing. But I thought zince was mostly removed from oil? Makes me wonder what the zinc level would have been 10 years ago. What is a good anti-wear level of zinc? How much is enough?

The other thing I notice is that they only list universal averages. Doesn't compare your sample to the same kind of oil you're using. How valuable is that, I wonder? I guess the only way is to also send in a sample of fresh oil right out of the bottle so you have a baseline. That way you could tell how quickly the additive package is being used up.

Yeah, I knew it was way to soon... Dealer mechanics told me they like to change every 2500 miles... Granted, thats probably regular oil too...but thats what I had in my head. Plus, it was right before a 1200 mile trip to Deals Gap, so I wanted all fresh for the trip with temps around 100 degrees outside for that weekend. Pretty **** I know...lol Pretty good questions too.. Thats what I like about the forums, someone can really learn alot! Thanks for everyones comments and suggestions...

I generally change mine at 2500 miles, whether I'm runnin' synthetic or dino. I worry more about fuel dilution since my Sloptail has a carb.

There is some silicone in the oil. The universal average is 9 - yours is 12. So some of it must come from the oil Where does the rest come from? Maybe from aluminum wearing? You do have a little more alum than the universal average.

I guess without a clean baseline test with your brand of oil, you really can't tell anything from follow up tests.
