I never did the piston soak as I mentioned a few posts ago. I did however run 1 quart of Dexron VI in the motor for about 500 miles since I was 1 quart down on a 5K mi OCI.

At that point I did an oil & filter change with the motor hot. This time I brewed another repulsive concoction. I used Shell Rotella T6 5w40. I also added 750mls of the silver can 'Engine Restore' in addition to a full 8qts.

I am now approaching 3K miles and have checked the oil levels every week since the last oil change, Nov-20th, 2010. I've only used a 'smidge' of oil. This is a drastic deviation from my oil consumption issues since owning the vehicle 2 years now & 38K miles ago. Typically I would have used a full quart by now.

I intend to take the oil change to 5K. I'll update either then or whenever i'm 1 quart down.

Next oil change will consist of just Rotella T6 5w40 and a fresh filter.
