7000 mile oil change intervals are fine with sysnthetic oil..if it is a good running Subie Perhaps shorter if it doesn't run like a Swiss Watch
Shell Rotella T6 5W-40 is a great choice
Or any synthetic oil from 0W-30, 0W-40, 5W-30, or 5W-40 would be fine if you wanted to pick an oil on sale...

I've only had good results after 7 or 8 years of using LCD products like LC 20 / FP 60 in all our family vehicles.
I have a Duramax, a bunch of Subaru Outbacks, VW TDI's , BMW 3 Series, and a Jeep Cherokee.
I have been pretty good at using the products frequent but not all the time.

Run Auto RX or Lube Control LC20 with the Eneos and see how oil consumption looks
Or use same program listed above with Redline 5W-20 oil
Make sure daughter has extra quarts of exact same oil and that she checks oil level regularly!
Why not give a BMW the good stuff?
I like GC 0w-30 but there's nothing wrong with a 0W-40 , 5W-40 or 10W-40 in a high quality synthetic from Redline, Mobil even Shell Rotella 5W-40 15W-40 HDEO seems like its ofr a beater BMW in hot weather, or for cleaning...
I like 5W-20 or 0W-20 in our Honda Element VTec engine
If it was driven in 100 degree heat like in Houston Texas or Orlando Florida then maybe 0W-30 Castrol GC or a 5W-30 would be smart.
In 100 + heat like Arizona or Las Vegas, Nevada....then maybe 5W-40 or 10W-30.
In all cases, I would use...
Redline and GC 0W-30 run great in my german cars [ especially the BMW's ]
M1 TDT / Delvac 1 5W-40 is also excellent
I also run Pennzoil Platinum, Eneos, Valvoline Synpower and can find nothing wrong with them... but Redline, GC, TDT are my favorites

I have run our 2004 Honda Element 2.4 VTec on 0W-20 or 5W-20 synthetic with Pure One oil filters since new... now at 100,000 miles engine runs beautifully with essentially zero oil consumption over the 7K interval I...
