Re: 10w-40 or 20w-50
I understand all your statements. But, were talking about extremely warm regions here. Example, Florida. I've been using 20/50 oil in all motors for nearly 20 years on all motors during the warmer months. Live in Pa and never had a problem with any of my engines. Due to lack of lubrication or any other internal problems for that matter. Yeah, if it was Febuary and the current temps are below lets say freezing. Obviously, you wouldn't want to have a higher viscosity oil than what the manufacturer suggests. And I'm not the only one who has done the same under the circumstance and never had any problems. All your statements change theory under warmer conditions.
