Engine oil OEM Subaru or OEM Volkswagen

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.

2008 VW Beetle is a 2.5 liter 5 cylinder. Yeah, 5 cylinder. It takes 6.3 quarts

I ran this exact oil in my late B5.5 1.8T, and it worked great, until some lady blew a stop sign, t-boning me and totaling my car. But it wasn't the fault of the oil, lol.

My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.

I switched to 5w30 and it's all good for 5000 miles

Part number for the oil: G055512A2 $14 (x2) O-ring: N90362001 $4 (x2) Paid ~$38 total Yeah my dealer is about 40 minutes away so I bought two in case I want to order oil in the future and do this again sometime...or if it leaks for some reason and I have to drain/refill, I just didn't want to drive back.

Put 100k miles on my mark iv jetta tdi while using the stuff. No problems.

Well, some manufacturers do have way shorter oil change intervals than Euro manufacturers. The Subaru severe driving interval is 3000miles/6 months, and I do lots of short trips in a desert climate so I usually try to be around 3-4000 to stay on the safe side for warranty and whatnot.

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.

Well, just got back the test results on for our oil analysis, here are the comments: " Nothing showed up in this sample that's too much of a surprise, though aluminum and copper are perhaps a little higher than expected. New parts wearing in tend to leave a lot of metal in the oil and that's what we suspect is going on here. You ran this oil pretty long for factory oil (we realize you were probably only following the oil life monitor). So that's why aluminum and copper are on the high side. No matter--everything should improve now that you've changed this fill. The TBN read 1.9, getting low but still okay. Potassium is from the EGR system. "

My Mk4 Golf is at 146000. And I've religiously changed oil and filter every 4000. One time I let this synthetic oil go for 9000 miles, it caused pre-ignition and destroyed 2 sparkplugs, needed a tow, and a expensive sparkplug replace at VW.
