I am willing to concede that I might want to try a different oil weight and brand. Any suggestions?

I think we just find a lot of people on this forum that say BMW is smarter. If BMW is so smart, then why didn't they include the oil cooler on the early models then back track? Why is BMW trying to make the 1M run colder? Why did BMW put an absolute piece of garbage intercooler on this car? Why can't BMW make a HPFP that works? Why do the injectors constantly fail? I am sorry, but to me BMW doesn't look so smart at times.

Agreed, Im am trying to talk to Chad about just ordering the thermostat and he hasnt gotten back to me yet. I too have a second oil cooler and the temps usually stay around 220 and when I run it hard it goes up to 240 and stops. I would like to bump that down to 200ish daily and 220max. Let me know if these are similar to your results after driving a couple days FBIS. Nice install. I wish I had seen this before I put my AR kit in. They gave no directions and the fitment was a CUSTOM job to say the least. I will post some pics after I get it back tonight.
