Engine oil OEM BMW or OEM Subaru

I recommend checking your oil level at 3000 miles because some vehicles burn oil. BMW and Audi especially, at 1500~2000miles I will top off.

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

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.

BMW used to recommend you changing oil basically every time you blink, back when consumers paid for 100% of all maintenance. But in order to be more competitive, they began offering 3 year included free maintenance on all new vehicles.

Looks to be exact same procedure as on my e46. Perhaps the easiest oil change I've ever done. In fact, I've used the same brand and spec oil too, which is an BMW LL-01.

Based on extensive testing, BMW has approved only certain engine oils. Use only approved "BMW High Performance Synthetic Oil." If you are unable to obtain "BMW High Performance Synthetic Oil," you can add small amounts of synthetic oil in between oil changes.
