I’ve posted a couple of threads about my 2009 Scion with the oil burning 2az-fe engine so I won’t elaborate here and just jump straight to the question. What oil and change interval would you use if you were trying to flush out your oil control rings? I was thinking a synthetic 0w-20, but that’s mostly because I have a few bottles of Harvest King I don‘t need. Maybe a couple of 2000 mile changes and then reasses?
The engine specifies 5w-20 or 0w-20. I know Royal Purple has a lot of detergents so maybe a jug of it to start?
