Here's a link to the scanned report:


Previous thread: M1 10w30, 7519mi, 2003 Subaru WRX wagon 2.0 turbo

I might try running out to 9k miles on this interval. Otherwise, nothing different. Any comments?

Argh, anyone know why using code tags doesn't use a fixed width font anymore? Sure makes reading the data hard.

Who knows anymore with this board. Its been mentioned before.

Unreal report and also the previous reports are a model of consistancy. Makes me want to go out and buy a subaru. 440F Flash

and .2 insolubles. Thanks so much for posting this report. Yours is one of the most interesting posts I have seen in quite a while. Thanks

ANOTHER boring Subaru report.

Truthfully, these boring Subaru reports are a very big reason I drive two Subarae (isn't Subarae the plural of Subaru, or, would it be Subari?) I have to put on 50,000+ miles per year on a vehicle, so, I want an engine that will last. Plus, the AWD is nice in the snow. Plus, the leather seats in the Legacy are surprisingly comfortable. The Legacy and Forester were just awarded "safest in their class" status, too....this doesn't guarantee anything, it just demonstrates they are built decently compared to other cars. I just hope Subaru continues it's attention to detail, as I'll have 1/4 million miles on my '07 in 5 years, and will be looking to buy another. Thanks for boring us with your report! B-)

The 2.0 turbos seem to be a little easier on oil than the 2.5's as far as the oil staying in grade and wear metals.

Dave, how did you break your car in? Easy for the first 1k (according to the manual) or by driving it hard? You could be the poster boy for Mobil1.

Odd, what browser are you using? It looks fine to me in Safari and Firefox.

BTW, nice looking UOA!

I just had an UOA after 6961 miles with my 2.5, viscosity 58.1 (expected 56-62)...the 2.0 Turbos are easier on oil than that? That would be impressive to me.

Break in was pretty much by the book, first 1000 miles was varying freeway speeds and loads but did my best to keep RPMs below 4000 as recommended by Subaru. Hit some good levels of boost and vacuum during that period as well while varying the load, but nothing too tough.

I bet he means the 2.5L turbo engines, not the NA 2.5L engines.

Using both Firefox and IE on Windows it uses a variable width font in the code section for me (I can post a screen capture if you want). If you look at my previous report (linked in the 1st post) the data there lines up nicely.

Thank you. Sometimes my fingers are faster than my brain.

Dave,

Nice! Your motor seems to love M1.

FWIW, both of your posts look fine to me (on my Mac) using the "code" tag.

Looking at the raw HTML, the difference between the old post and the new post is that the old post uses this
tag for the code:








Where the post in this thread uses:








For some reason my browsers isn't defaulting to a monospace font for
code and for some reason the forum doesn't generate the pre tag which explicitly states that a monospace font should be used.

Dave when did you last change your air filter? Just wondering what the service life is.

Also the NA and K values seem to trend in tandem at times.

Do you think he has a really small coolant leak?

Last changed the filter at 60,600 mi or about 12k mi ago, I haven't checked it recently, but the changes before that were at 49,300 and 30,200 all on an OEM filter. At 19,500 I did try the Amsoil foam filter, but swapped it out as I didn't want to hassle with cleaning/oiling and the OEM filter seems to do a good job.

I hope it's not a headgasket leak! Is it just me or does it trend with SI, too?

 

[UncleRunkle]

The trend between al three is more tenuous than just between Na an K. I would suggest maybe Dyson analysis on the next UOA. The amounts are small and don't appear to effect wear at all.

 

[edhackett]

Dave, what coolant are you using? Subaru coolant has almost equal amounts of Na and K. If there was a leak, you would expect to see equal amounts of Na and K.

You might be picking up Na from marine sources.

Hi Ed,

I used Subaru coolant up to 60k when I changed the coolant myself (dealer service at 30k so I assume they used Subaru coolant).

I'm not positive what brand coolant I used at 60k, but I think it was Peak Global LongLife... I'll have to check if I still have a bit of it left over.
