yeah those last two were both relatively normal driving, both using Rotella T 5w-40. I haven't really pushed the car as much since I'm getting a little nervous about the mileage.

The next UOA will be the first one with Rotella T6, but from what I can gather there really isn't a difference.

Don't be nervous about the mileage.

You obviously take great care of your car - enjoy it!!!

I'm curious about the amount of calcium in your most recent UOA's. Is it a new version of Rotella? Calcium is used as a detergent. Either way, doesn't seem to be hurting things.

Thanks a lot for sharing - this is very educational for me to see the patterns with continued use of RT.

Any chance you added some octane booster or fuel additive of some kind? This happened to my UOA once. I had ran octane booster several times, the Lead came back very elevated. I quit using it and it went away.
