If you are concerned with flow if ambient temps reach -40C this winter, you may want to consider an oil pan heater in addition to using Mobil 1.
But for now, dumping the RP is just throwing money out the window. Is your car garage-parked overnight? If so, even less to be concerned about.
Nothing wrong with RP. Only problem with it is the price. There are better options for less money.
The focus should be less on oil, and more on a healthy battery.
It’s about the flow i’m concerned at lower temps. I realize that RP does work but in comparison to Mobil1 it doesn’t flow the way i want it to work in winter months. I don’t always plug in and park indoors. The answer to my question is to run the winter months with Mobil1, pretty simple solution. The temperature around these parts can dip down pretty quickly -9 today, -22 overnight, 2 days from now, who knows, it could be -27 or -34 celuis. Our climate up in this area of the country can jump to extremes at anytime between Nov-Mar.
