Castrol Edge 5w-40 5k mi; 2012 Sienna 2.7L 1AR-FE 190k mi

[JZiggy]

First UOA on the Sienna, 2.7L engine with 190k. I've been running 5W-40 because it helps with the cam phasor noise on startup.

This is the same engine that I did the piston soak more than 30k ago. Doesn't burn a drop anymore.

Nice to see that it's wearing normally.

Thoughts, ideas, comments, sarcasm, all welcome...

190k with excellent UOA.

Looks good. "Let it roll, down the highway!"

It's a small engine with a big job to do. It's hammer down all the time, but seems happy with its lot in life.

All a small engine can hope for.

Is this Edge 5W40 a Euro A3/B4 oil or a C3 oil or neither?
Just asking as I was expecting a touch more zinc if it was A3/B4.

Either way, nice report.

Blackstone Labs doesn't display TBN anymore or it's tested at additional charge?
If the TBN is 2 or lower - the oil is gone.

You only get TBN from Blackstone if you pay $10 more.

Correct. At this OCI I highly doubt the TBN is low yet.

Yeah. It starts at 10.6 and in several of my UOAs with this oil, it's dropped to 7 after 3500 miles and 5-6 after 5500 miles
