Need your help.

Picked up a 2019 Subaru Ascent the other day and owners manual says first oil change is 6 months or 6,000 miles. My plan is to change the oil at 1,000 miles to clear out all the oil after the break in period. At 6,000 miles I'll change it again to stay on schedule so I don't mess up my warranty.

The internet says a ton of things and I can't get a good answer.

I asked the Subaru peeps... and they're leaning towards the manual, but 3,000 miles if used under severe conditions. I keep cars for a long time and just want the best chances on this little 2.4L Turbo.

When would you change the oil?

Let the fighting begin...

My experience is biased since I've only ever leased a brand new vehicle. 2017 Subaru Outback. I got a sweet deal on the lease and know I'm not going to end up purchasing it. First oil change was free at Subaru so I waited till 6k.

As I have an old car I used to change the oil every 4000 miles. After a few years, I now change oil every 2000 miles. I think I need to change something in my car. But I'm not an expert, often I just use car service.

I got a new vehicle last year and researched this topic pretty thoroughly. All of the reliable info I could find stated it was not necessary to change the oil outside of the manufactures' recommendations. Today's engines supposedly do not have the metal filing issue and seating issues of older vehicles. Nearly every manufacturer out there is now recommending at least 5K at the first oil change and Toyota is at 10k now? With lifetime powertrain warranty? I wouldn't sweat it and I decided to just follow their protocol.

Although, its certainly not going to hurt if you want to do it early.

Had a few brand new vehicles over the years and always did first change @ 500 miles. Oil is cheap, engines are not.

I always change new engine oil at 500 miles. Just a drain and fill. Can’t hurt. But I suppose it could hurt to wait, especially on a Subaru... not being biased, they have had extended open recalls for 100k-120k mile engine replacements historically

No you leave it in.

It cause 0 harm, and maybe helps seat things in better. But mostly it causes no harm to leave it to their recommendations.

Engines take like 15K miles or more to really "break" in. But like said above it isn't like the old days.

You will do what makes you feel good, but in my aircraft mechanic type of thinking from my training I would just leave it be. At the oil change I would switch to synthetic oil. I run it in my engine, (except my cruiser as it leaks too much on old seals).

If you do change the oil try collecting it and thin it out a little and run it thru a fine filter and let us know if you see metal filings. Curiosity eh.
