This is the Final Report on my 2011 Tundra Crewmax 5.7 4WD - I just sold it this week. With my daughter moving across country to go to college, we would have had 4 vehicles and only 3 drivers, as my daughter must live on campus for two years and won't need a car. Plus, there was one full year of tuition, room and board tied up in the vehicle, which I could use. So, off it goes. The only real thing of interest is slightly elevated silicon, which, once again, I attribute to sealants in the engine, not bad air filtration like the report suggests. You can see the same pattern on the last 10K run. I also saw the trend in my 2006 Tundra as well. I do have some general observations that I plan to post in oil analysis general questions forum.
