188K on my C36 that gets thrashed on in high heat, high speed environments, (Las Vegas NV) on 15/40 Rotella T 5K OCI and less than 1/4 quart usage between changes- if that, most likely due to temp changes. No leaks, no funny sounds, no nothing.

I also use it in my 81 280E with 77K on the odo. No issues, none at all.

Can't beat it from a price or performance standpoint; the rest of the stuff on the shelf is made for newer cars, I don't trust that backwards -compatible BS they claim. No reason to.
