How long will the 156 be available for? I don't see it on your site anymore.
So far it works awesome in my 420 hp Subaru boxer engine.
I kinda want to keep using he 156 5w30 oil, as I am the only guy among the local Subaru enthusiasts that has oil that can be beat on, but doesn't have appreciable oil consumption, even after a couple of track days.
I am worried about using the 5w30 oil this summer on the track with possible 100F weather. I was thinking the 5w50 may be better, as it is kinda a race situation.
On the other hand, my car is my daily driver, and it sees -40F in the winter.
