Engine oil Motorex or OEM Subaru

I would also make sure that every time you fill up the gas you check the oil dipstick and if it’s a little low top off the oil. In fact, I think this is probably crucial to owning an older Subaru like mine mine has 300 K.

I second those saying bring a spare quart of oil. I wouldn't be too worried about taking my 2012 Outback at 170K miles on such a trip...but would agree check the oil every 1000 miles or every morning (depending how far you go in a day) just to make sure it isn't getting low.

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.

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.

Take a quart of oil with, especially if you don't have reliable data on how much your engine burns. Check it occasionally and top off if needed.

In my Shiver 750, Motul or Motorex every 3,500 miles were required to keep neutral findable when you want it and hidden when you don’t. False or impossible-to-find neutrals were a sign that it was time for an oil change.

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.

Use an oil designed for a wet clutch, like this [motorex 15w50]

I paid $90 bucks for a full oil change the first time, using motorex. now for my 2nd change, she's getting Rotella T6 because it's cheaper. I put on too many miles a month to shell out $90 bucks every 3k miles.

Having had multiple Subarus that leak oil like crazy (they all do when they get old) the leaks are most likely too much for the stop leak additive to fix anyway.
