You realize those two statements are contradictory, right?
Why is it not advisable to run a thinner lubricant, unless you self-create the thinner lubricant by diluting it with mineral spirits? Surely a fully formulated lubricant of lower viscosity is going to offer more predictable behaviours than a heavier lubricant dosed to be thin in this manner
The thinner oil component added will burn off gradually, and the hope is that it will disappear as warmer days take over later. Others have noted that natural fuel dilution during winter "automatically" lowers viscosity in cold weather, only to recover more viscosity as it burns off as the weather warms up. If you can't count on fuel dilution, as it varies by engine and driving style, then MMO or SeaFoam or Gumout Multi might help lower viscosity
temporarily for you in cold weather.
This philosophy certainly hinges on a lot of "if's" and "should's" via the process of diluting a fully formulated lubricant with something that isn't one
I also don't think we can draw parallels between diluting a fully formulated lubricant with kerosene and using a fully formulated lubricant that simply leverages thinner base oils. One we know the physical properties of, the other, we are apparently making a WAG and counting on what, temperatures staying low to retain the effects and the oil getting hot enough to disperse it later on? What happens if you get a warm spell? You lose the cold temp "advantage"? Seems pretty hokey to me.
