There is a fair amount of speculation online about why Subaru changed their recommended interval from 7.5k to 6k, but no definitive answers.
I am almost due for my second 0w20 change at 12k miles on my 15 Impreza. This car does not require makeup oil between intervals (can't say that for my previous Subaru).
If l get a UOA with 6k miles on the oil, would it be safe to stretch the intervals out to 8 to 10k based on analysis results? I don't see value in getting only 6k out of synthetic oil especially when some other manufactures recommend 10k.
Should l just follow the 6k intervals and call it a day? I have a fumoto valve and the oil filter is ridiculously easy to change on this vehicle.
I'm curious to hear what the BITOG crowd weighs in with.
