Blackstone results (post your UOA's)

Northwest Tan · 01-25-2006, 07:24 PM

During the last oil change interval I had a coolant system failure. The radiator split at the top where the plastic meets the aluminum. I had to drive with no coolant to a safe spot. Needless to say, the temp gauge was pegged high whenever the engine was running.

Everything turned out OK! Here is the engine oil analysis:

Good news. I hate the plastic topped rads. It's just hard to justify replacing a fully functional rad on a daily driver though.

Koyo makes nice all aluminum rads for a good price.

Here's the story behind those results.
I was planning on changing the oil out at 11250 miles as per the manual, but as per usual, my plan went bye-bye.
Just before my target change date, we got a call that my Uncle passed away and we had to make it to a funeral in NYC.
No time to do the change, so we jumped in the car and made the 1250 mile trip in just over 17 hours.
Before we left, I had added a total of 1/2 quart of make up oil.
If you do the math, you can figure out why the other quart was needed.
We were traveling 3 digit speeds for a while, but mostly running 80-90 (eating gas like mad) and the Sube engines don't like that much (unless you run a thicker oil).
I added 1/2 qt in Fayetteville and the other half in NYC.
We took it easy going home (65-70) and added no oil (it was down less than 1/4 when we got home)
I'm glad I use a 40 weight oil, otherwise I probably would have had to put in much more.
The oil was dropped the day after we returned home and sent in for the analysis.
Since then, I've put on another 2k+ miles and haven't had to add anything yet.
We're going to Dallas next week and will probably do another change when we return. Stay tuned.
I guess the equation should be: boost = oil consumption.
Plan your oil weight choice to match your climate AND driving style.

Here is my report for the XT. I'm planing on doing the 98S with her next oil change.

You should try German Castrol Syntec 0W30. It's very shear stable and I've seen some great results in 2.5T's over at bitog, including someone that ran it in an STi with 45 passes at the drag strip with over 4k miles on it. Here's my last:

Quote:

I drive five miles each way weekdays and made a trip to SC (100F temps) and MD (upper 90’s). This summer was one of the hottest on record in NJ so this oil saw a lot of days in the 90’s. I also drive on the beach. No engine mods.

I swapped out my Amsoil air filter for an OEM one and I’m a little surprised that silicon didn’t drop. Maybe it’s still breaking in? Copper went up a little as well.

I changed the oil after the UOA at 7,500 miles and maybe I’ll go to 7,000 on the next UOA. Or maybe I’ll just save my money and not bother with UOA’s because I have faith in the elves, regardless of vintage.

First column is current, second column is Green GC with 5,930 and third is M1 5W30 w/5,774.

Equipment make: Subaru
Equipment model: 2.5L Turbo
Oil use interval: 6,144
Oil type & Grade: Castrol Syntec 0W30

Properties
SUS Viscosity @ 210F: 64.4
Flashpoint: 385F [>385]
Fuel %: .5 [<2.0]
Antifreeze: 0 [0]
Water: 0 [<0.1]
Insolubules: .4 [<.6] [same]

Dennis: The small amount of gas was still there in this third sample so it may be an operational hazard you will have to live with. It has not hurt the oil’s viscosity any and we don’t see any harm being done to wear. Unless the fuel amount in the oil gets much above 2.0%, we doubt we will see any harm from its presence. Copper made a little unexpected uptick in this sample and we have no idea why. It comes from bronze parts. It should read at about 5-ppm in this sample. We will watch it for you next time, but we would bet it will drop. The TBN was 3.6 okay.

I've considered it, but I tow around a 1k lb. trailer for my work and feel more comfortable with the 40 weight.
The next time I can plan a 17 hr/ 1250 mile trip (not!) I'd probably go with the M1 15w50.
Generally, I'm happy with the M1 product.
This oil cycle was a fluke.
Thanks for the feedback.

pleiad7 · 02-25-2006, 07:15 PM

I finally found my Blackstone report from last year. I will probably have another one done after the next oil change at 60k. On a side note... I just noticed the mileage on this report and realized that I've nearly doubled the mileage on Subed within the last year. :drive:

SubaJew · 04-03-2006, 07:32 PM

New sample results attached.
Note that even though I'm using M1 5W-40, it's shearing down to 5W-30.
Something for all you 5W-30 users to consider.

Dan · 04-03-2006, 07:42 PM

I really need to remember to order some kits one of these days. With 3 boosted vehicles and one of them at 160k miles, plus an 18 year-old rotary, it's information I need to get. Guess I'll get with my brother and see if he wants some kits, too.

"Nice improvement in wear" is right! Your wear metals look great and your engine broke in quicker than mine.

Don't you know that thin is in? :-) There are probably thousands of people driving around with oil that sheared down to a 20 weight. If you're concerned about the shearing, go with an ester based synthetic and see how that holds up (GC, Motul 300V, Redline, etc.).

Well, I finally got my kit in the mail this past weekend. I can't wait to send in the sample after my next oil change.
