bad ‘ inaccurate , not explained correctly, bad advise, really old school very antiquated information for a Turbochargers in this decade or just wrong information in RED!

Thanks retread 888. This is accurate, common sense information I actually expected when I posted. But then I received crazy, overzealous, and interesting information to say the least. Yes, Mazda did lower there compression ratio for the Turbo as necessary. And even at that 10.5:1 is one of the highest for production turbo car. Of course I'm sure you already know they were able to do that because of the design of the Skyactiv technology. Yup, I was aware of the additional heat produced by oil passing through turbo charger. Those things do get hot, old school or new School 😁. Yes, I think I wil just keep changing my oil when it gets dirty. Around 4k.
I did break it in properly. 👍 I was lucky enough to get the Mazda right off the truck, (watched them pull it off). So no crazy test drivers hammering it
Thanks 888.
