When I pulled my spark plugs, there was no oil on them which means there's no blow by (i.e., no oil is getting past the rings). Given that, I'm doubting the MMO will make it past the rings to the oil holes. The MMO needs to be applied *under* the rings, not on top.
I went the Rotella route, and burned 1 qt during the oil change window. Then I noticed that it's 5W-40. From now on I'm going to run:
a) 50% Rotella 5W-40 w/
b) 50% Mobil/Royal Purple 5W-20
This way I can
a) get a detergent in there on a consistent basis and
b) make sure it shears down to a 30W when it is up to temp. I'm afraid that 40W is making the engine work that much harder.
For oil top offs between oil changes, I'm going to use MMO. Hopefully, with the Rotella/MMO mixture, at some point this thing'll stop burning oil w/out me having to rebuild it w/the newer-style, 4 oil passage pistons.
