Engine oil OEM Mazda or OEM Subaru

OEM Subaru Engine oil

Check all your fluids ASAP. If any are low, top off as per the manual and monitor closely before you leave to make sure it's not leaking or consuming anything. Definitely bring extra oil, 1 or 2 quarts would be pleanty, and some paper towels and rubber gloves help too.

Pros: bring extra oil
Cons: engine drinks oil
Vehicle: Subaru
Mileage: 3500 km

OEM Subaru Engine oil

Should be fine, but CHECK THE OIL FREQUENTLY. This series of engines is notorious for oil consumption problems, which may not appear at all when doing short trips, but suddenly it's drinking 1qt or more per 1000 miles on the highway.

Pros: check oil frequently
Cons: oil consumption problems
Mileage: 1000 km

Yes, it is good advice. When a new engine is breaking in, there is a lot more wear metals. It's not uncommon to see metallic flakes or shimmer in the oil during your first oil change. Parts wear/bed in. That's why there is a break-in period on almost, if not all new cars.

I did my first oil change at 1k miles on my BRZ; I saw a lot of metal shavings come out of the oil. The oil also had a metallic shimmer to it. This is totally normal, but I want to get rid of all of that so it is not circulating around the engine post-break in period.

Pros: removes wear metals, good advice
Cons: metallic shimmer

OEM Mazda Engine oil

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines]

Pros: best oil for skyactiv
Part number: 1WPE-14-302

After reading several posts I got the Mazda Molly and Personally really like it! With the Molly it seems to run much quieter not such a heavy tick and just overall feels better’

Pros: runs much quieter
Cons: expensive

For the record, this is NOT the exact replacement to Mazda 0W-20 GF-5 with Moly - Synthetic Engine Oil.

While this has high molybdenum, it's still a different formula from Mazda's own proprietary blend.

Pros: high molybdenum
Cons: different formula

I encountered something similar when I took my CE Turbo in for service a few weeks ago. The invoice said 0W20 and when I asked the service manual why they used the wrong oil they told me “oh our technicians know what oil to use, ignore that.” Needless to say I have zero confidence that the correct oil was used.

Cons: wrong oil used
Vehicle: Mazda
