Experience with my car: It eats coolant way more often than engine oil. No one seems to have an answer for that one. Best to keep a gallon bottle of coolant handy in your garage. Personally I trust 'Prestone' brand 'concentrate antifreeze/coolant' (full strength) from Wallymart. I ain't gonna pay for Toyota or Subaru brands of coolant.
Note: I am a former auto mechanic.

My car goes through coolant as well, but not too badly. Was starting to worry it was only me. Still puzzling. Maybe Subaru has decided to make their head gaskets leaky from the factory to get past the old head gasket failure problem. It's now a "design feature" lol.
I remember reading that newer engines actually have greater designed clearances than older engines to reduce internal wear, which is why we can expect to see 200k + miles on your typical car nowadays. The side effect is that some oil is burned during normal operation.
