I plan to do the first change around 1k mark as well. My thinking is, the new engine parts are settling into their design tolerances during the first couple of thousand miles and any extra metal material that is released during this is in the oil that will be removed with the change.

I've always went with first oil change at the 3000 mile mark. I see the oil in the XT has changed to 0-20W synthetic. May factor into why the manufacture is saying just go with 6000 for first oil change.

There's no known consensus. The Subie OM says leave it, other car manufacturers say leave it and counterbalance says take it out early to clear out the debris field.

I swapped mine at 2.5k, ran another 3.5k and then went on a schedule. My engine runs great with no consumption issues and the mileage is good. I have another car where I left it in for the full interval and once again, no issues. All backed up by UOAs.

IMO, I'd swap it out but I can't give you hard data that says it's an absolute benefit. Whatever makes you sleep better at night.

In a subject for another thread, I would shy away from the 0/20 viscosity and run a x/30 into we get a track record from the Ascents.

"If" there is any extra metal material....it will be in the filter. Change the filter; that is what filters do.

This all sounds like a lot of paranoia to me. If the car manufactures could get more money out of justifying more oil change recommendations - esp at the start where dealers would likely get the service - I am sure they would be telling you all to do it at 1K.
I'm gonna go by what the book says.
I see a lot of people online actually saying 500 miles for the first. Just think of how much damage you are all doing for those second 500 miles with all those sharp metal shavings bouncing all over the place. ??? Better do it at 500. ??
Seriously though, I think this mentality is based on old cars. very old cars. Most here seem to be people that dont even keep their Outbacks much past the 100K mark. (my first went to 250K and current going strong at 170L without a 1K oil change). Just my opinion.

Found this opposing opinion (from over 10 years ago):
"increasingly, manufacturers are recommending AGAINST any special short-term oil changes or magic oil formulas, generally saying this prevents a complete break-in program. in any event, to insure you can't be punted around on warranty in case of an issue near the end of the warranty period, change it exactly when your manual says to.

grizzled old farts who have heard enough stories and replaced enough engines laugh until they fall down and wheeze every time somebody repeats this information. they tell you exactly what kind of metal shavings, chips, and foundry sand come out of the strained oil and out of the cut filter on the first oil change, be it at 500 miles or 5000. as their eyebrows arch and their hands cup and swoop, your blood runs cold.

the truth is in between. there will be extra crud the first few oil changes. the finest particles of this slop do circulate with the oil and contribute to scuffing the piston walls slightly. this is said to be a good thing with the tighter tolerances engines are built to, and provide a ring/cylinder surface that doesn't cake with burned scuzz and cause oil leakage as the engine wears. the car makers say they take this into account... aka, you are the final machinist of the engine, and only if you follow their break-in plan can they honor the engine warranty."

If you're going to change the fluid why not do an analysis for posterity?
Seems like a good time to start doing them. I'm not sure I would ever pay to do an analysis for every oil change but it would be a good idea every once in a while to look for trends. I think I am going to do one soon on mine since I am going to be deciding whether or not to buy the car when the lease is up. A good or bad oil analysis might steer me in one direction or the other.

analysis???
I've never even heard of this.
Why do I get the feeling by this thread some people take better care and attention to the health of their cars than their own bodies.

welcome all new comers to such oil threads.:)
Blackstone Labs. (and maybe one other that escapes me), but go to their site, read price choices.
Or just read such threads here from others that have coughed up the money and posted the results.
(maybe someone will link something from the Ascent board on FA24T, to give us a idea )

Not sure if it’s my phone or what, but I can no longer see this uoa.


In prefer to type them so they don’t disappear in 6 months. I also prefer Oil Analyzer’s Inc for the reasons mentioned in that thread. Cheaper than Blackstone and they have the ability to test for fuel dilution using Gas Chromatography instead of always estimating it. But if you want the best in the business use Dyson Analysis.

I plan to leave the factory fill in for at least 3k to help with break-in.

I just figured the people that have the disposable income to buy a new car and change the oil 5 times as often as the manufacturer recommends would have the disposable income to spend $30 on an analysis for their own peace of mind and post it online so us nerds have something new to talk about.
