I am experiencing oil consumption on the order of about half a quart every 400 miles in my ez30d 3.0 H6 Subaru Tribeca. I made a similar post in the forum, but no one is helping.
I get a puff of smoke at startup proportional to the amount of time that the vehicle sits. No smoke when going down the road that I noticed. I am thinking valve seals or guides. I cleaned the existing PCV valve, but I think that I'll be getting an OEM one soon along with Seafoam of the engine just prior to swapping it out along with new HM oil just in case there is some obstruction to the PCV system.

Could someone suggest the most aggressive 5w-30 HM oil for a scenario like this?
I don't care whether it's Dino or Synthetic. Rotella T6 is currently in there which I think is fine for a quick temporary cleanup. Just got the vehicle and it looks like this was someone elses problem. There is no warranty and I'd like to avoid a new engine for as long as possible.
The oil cap was pretty caked up with oil.
Please help!
Thank you.
