In the UK, Subaru intervals are 10k miles on n/a cars because the rental fleets refused to carry Subaru's unless they agreed to the longer intervals (according to a Scottish poster at bobistheoilguy).
I know an Outback owner/Amsoil dealer that runs 12-15k miles on Amsoil, guided by uoa's. Some people aren't worried about Powertrain warranty coverage when they run a good oil in the first place.  He's also a former Air Force rocket scientist so SoA probably wouldn't get very far if he took them to court/litigation over warranty denial.

Turbo cars can also go 10K miles between oil changes as long as you use synthetic oil and keep up with checking and topping off your oil.
That's what I do with my GTI and I have had 40K miles with no issues and I run a big turbo setup and also do track days and autox.
