Default Oil analysis after 6,000 miles of alky injection

I just got back the results of my first Blackstone Labs analysis. I'm sold, and plan to keep sending them oil samples after each oil change. I have been running alky injection (50/50 water / methanol) for about 6,000 miles, and was interested in what the quality of my oil looked like. In general I am pleased by the results, but thought I would post them to the forum. The high silicon reading is interesting, I still use the stock intake and paper filter. Something to watch, I suppose. The discussion at the beginning of the paragraph is because I thought the oil was 10W30, but it turned out to probably be 5W30 (caught me... I had taken it to the dealer ). With the increased timing from alky injection, I was pleased to see a lack of lead content (read:bearings OK) in the oil. Anyway, here's the analysis, I have ~ 61,000 miles on the car, and use a 7 mm nozzle on the WI (have gone through nearly 10 gallons of mix in the 6,000 miles of WI):

Turn around time is great, but it takes about a week or two for them to mail you a sample kit. I took the sample earlier and stored it in a clean jar. A week later the sample kit arrived, and I transferred the oil to it. They emailed me the analysis (pdf file) the same day they received it.

Whats it cost for their Oil Analysis?

I've done it before with Caterpillar Diesels... but not for our cars.

Just curious! Interesting find!

Thanks

No lead. Nickel and copper is low. Aluminum is low so likley no piston scuffing either. Mine is due back any day, I hope it is better this time.

Nice results for a modded WRX! Do you have a modlist and details on your water injection setup? I assume you meant 0.7mm not 7mm injector in your first post.

How old is the air filter?? If it isn't that old/dirty, i would check the system for leaks.

I run my oil MORE than twice as long as you do, and my latest UOA showed less than a 1/3 that much silicon. (7.5K on oil, 4 ppm silicon)

Wow, thanks for the questions/feedback.

Honda -- yeah, the silicon is concerning. The stock air filter is actually pretty new, only about 7k miles. I will recheck how it is seated, and look for leaks in the airbox. My idle is rock solid, and boost is firm without any sounds of leaks, so I think the post-turbo setup is leak-free. But I'll keep my eye out for it.

Snvin -- full synth. Been that way since 20k miles or so.

Drees -- yeah, 0.7 mm WI nozzle, LOL. Here's my mod list:

VF-34, MadDad DP+3CE+Borla Hush, GP Moto-style equal length headers, STi pinks, Walbro, stock intake, SpeedFactor TMIC, Aquamist 2d injection, EcuTek custom tune, stock pulley (used to be underdrive, went back to stock) and stock bypass valve. Boost peaks at 20/21 lbs under WOT, with the cold I'll see 21.4 lbs, in the summer less. Tranny upgrades, to the extent it impacts engine load: 4EAT with ProTorque TC, Level10 valvebody, Amsoil synth ATF, ATF cooler, etc.
