/\ Check a few pages back for my latest analysis, Quadcam also had great result and both of us are on stock block.. Go for it. One thing I notice is that my oil still look very good/clean even after 2000+ miles of driving. When I used to use Mobile1 0W40, the oil is already dark when it reaches 2000miles.

I thought I'd add some data into this thread.
I have an 07 stock block HR-TT with about 21K miles, roughly 4K boosted. Sorry, I don't have exact mileages. The shop that did the work switched the oil out from the dyno that the dealerships use to M1.

Did you have the M1 in for the "roughly" 4K?

With that kind of mileage the M! did real well, too well. From what Ive seen it shears to about 12cst and iron is a bit higher. Resample it again in another 3-4K. M1 0w40 again?

OK, I read the whole 39 pages of this thread and the amount of info is amazing. Thanks to Resolute for doing all this, and thanks to everyone else for positng your UOAs.
Of course, as it happens, I do have a question :-P
I think I want to go with either GC 0w-30 (if I can find it), or Mobil1 0w-40.
I see that the Mobil1 0w-40 has great results but it seems that it's mostly guys running FI use it. Would it be suitable for my stock daily driver, driven fairly conservatively, in Florida, assuming a 5,000 mile OCI?
Also, would USA-made Castrol Syntec not be good for 5K-mile OCI?

Will and I have both run the M1 0w40 and we are stock. His are part of the tables at the front, I dont think mine for 5K are yet. I have it in now and will run for 7500. The Syntec hasnt done awful for 5K runs Ive seen, but there are much better oils for the money including regular old GTX.

Here's my oil analysis results. I think this is the first report for Torco oil. Here are the details:
Oil: Torco SR-1 10W30
Engine: VQ35DE, rebuilt
2600 miles on engine, 930 miles on this oil change (4th oil change)
Wiseco pistons, eagle rods, Cosworth bearings
Any info appreciated, especially comments from Resolute

I dont know how many samples you've submitted but as you can see your molyb stands out. MolyB is a type of grease used in engine components and most likely just a little excess from the regreasing of engine components.
I saw this is your 4th oil change. Have you been submitting samples for the previous 3? As your engine breaks in a lot of metal particulate will show up at first. As long as the trend is decreasing I'd say your doing fine.

As far as wear is concerned, the values all look very good for a TT engine with 4k miles of use.
The high Si and Sodium are a concern. Neither are used as part of the additive package in M1 0W-40, so this is not normal levels for this oil. First, and most obvious, is double check the air filters and vacuum hoses for any leaks to allow these elements to be ingested into the crankcase. There are a number of other ways these elements could become elevated in an oil sample, but check the obvious solutions first and get another UOA during your next change to check trending.
