I am feeling like it's going to blow up lol. Thank you for giving me the go to drive it lol.

To be clear, I'm not saying it won't blow up tomorrow, either! I can't say either way.

If it were my car, I wouldn't necessarily park it until the rod bearings could be replaced, but I definitely would minimize driving until then. And I'd do everything I could to get the job done sooner (other than going to a shop that wasn't the absolute most competent one I could find). It's not the probability of failure I'd be scared of; it's the fact that these engines are not cheap to rebuild, and word is the remans don't last as long as the factory-built ones on average (no surprise there).

160529 miles on the engine at the time of this sample.

For about three months right at the beginning of the OCI, the car ran only a few times, only for moments at a time, and only to move in and out of a garage, occasionally without its O2 sensors. Also, I discovered a failing ignition coil just after this oil change, so presumably it wasn't doing its best work near the end of this OCI. Not sure if either of those is noteworthy WRT wear but they're all I could think of that happened during this OCI other than normal driving.

Trying not to think anything of the still-low-but-higher-than-normal aluminum number... 😬

I did this oil change when the oil was coming up on 1L low, so the "lube added" field underestimates oil consumption. It was closer to 1L/1600 mi on this OCI.

Not sure why the lab is still flagging Ti here....

First sample on a recent-ish purchase here. Clevite tri-metal rod bearings ~30k miles ago, 4 oil changes since. Silicon a bit high.
