Noise has continued to increase. My service manager feels it is piston scoring and I am getting a new block under warranty. Bye 0w-20.
I started getting the noise around 47k miles. It is most pronounced for the first few minutes of operation. It smoothes out but never stops altogether once the engine is warm.
