gotcha. first oil is the OEM 5w30, second oil is Pennzoil Ultra 5w30, and third is Amsoil ZROD 10w30. It's interesting how much variance there is.

Thanks for the info

Thanks for the info

Z-ROD has no tin in it's formulation.
Even with the autocrosses you have done, the overall wear values are quite good.
Thanks for the info. Thanks, I think the oil did okay for the number of runs I did on it.

If it continues or gets worse, it might be time to start considering what might be wrong.
OT, what's so special about this oil?
I can't see anything special in the add pack.
Why not just run M1 0W-40, an oil with all of the important certs that would also cost less and call it a day?
Thanks, I'll definitely continue to monitor. Just thought it was odd that it suddenly showed up. Maybe the motor doesn't like the oil?
I'm actually in the process of testing a bunch of oils for the Mini. This was just one of them. This is supposedly quite good for the Evo, which does a lot of (1) sitting for long periods of time and then (2) run pretty hard at autox & is turbo. I have a list of a few others I'll be testing for next season, I just don't drive the car all that often except for racing.
