Yeah, a good point that is often missed is the non-LL01 oils should be changed sooner. 300V is 3-5k miles. I mostly drive on the weekends and the track, so the mileage limit works for me.

Does Redline mention a mileage life amount on their high HTHS oil that you mentioned?

Switching back to coolant temps: I’m going to flush with distilled water and a wetter this/next week for the summer. Should improve heat removal by ~20%, which is significant for those of us hitting 240F+ coolant temps on track.

Boiling point should be around 250F under pressure, so will keep an eye on that as well.
