My wife's '14 2.5L Forester had oil change interval set to 7k miles from factory, so it's had that it's whole life, now at 75k miles. Always factory filters because warranty and because bypass pressure.
Ran the 0w20 idemitsu for the first few changes, it would drink about a quart in 7k, then started using the BMW 0w20 and it used only a half quart. Last oci I mixed in one quart BMW 5w30 (LL01) and it has yet to burn a drop in 5k miles.
I can’t imagine any 0W-20 having problems with only a 6k interval.
Never heard of a 7k Subaru interval. The interval prior to 6k was 7.5k.
I used to get hung up the higher bypass of the Subaru filters. Besides, Subaru can’t deny a claim for using a filter other than theirs.
Yeah it seems like all the newer cars are 6k. Ours was set to 7k when we bought it new, and reset to 7k after the two free changes we got from the dealer, so I've just stayed with that.
You can set the service interval to any mileage number you choose, or even by date, which is really great. However you can only change the mileage by the thousands, not hundreds. So you can't set 7.5k mileage interval, only 6k, 7k, 8, etc. So perhaps that's why?
And I do have a weird thing about using factory oil filters. Every vehicle I service and have ever owned. I'm trying to get over it haha. I did recently get a fleetguard stratapore for my 24 year old ford diesel... we'll see if I chicken out last minute and grab the FL1995
