My understanding of viscosity (and ambient temp effect on an ICE) is different from yours, but I’m no subject matter expert.
Are you a petroleum engineer?
I worked as an expert in diesel oil certification for Mercedes-Benz for over 50 years. I have worked as an expert witness in many Court cases. Let’s just say the Petroleum industries reputation for obfuscation is well deserved. One other point to remember, modern oil is now considered to be an integral part of the emission system. Fuel economy and wear protection are not friends.
