i guess I know very little about gas, because i didnt know there was a winter blend....
yea, that's new to me too.

That's going to be 85% WMO and 15% Gas. The gas is what helps bring the viscosity down to a level that's about the same as diesel. It also has anti-gelling properties that'll keep the oil from thickening up.
Gasoline is used purely as thinning agent [ a cheap one at that ]
There is generally no Anti-gelling properties in winter blend gasoline
Multi grade Motor oils should never plug or thicken up at low temperatures,
Most multi grades oils start out as LOW Viscousity oils ,then have polymers [ viscousity index improvers ] added to handle higher temperatures.

Cheap? Seriously?

Wrong.
Winter blends have a higher proportion of shorter chain Hydrocarbons [ at the butane end of the scale ] The side effect is that it is more volatile [ higher vapour pressure ]
There is also winter blend Diesel to. It is closer to D1 in chemical properties. With Diesel [ D2 ] there is parrafins added for pump lubrication, this is what plugs filters in cold temps [ CFPP ] "Cold filter plugging point"
Winter blend diesels can have anti gelling agents added

Yes they do. Ever try to add a quart of oil into a engine at -10*?

The term "weight" is often misused, it is actually the temperature operating range.
The same goes with the term viscousity! it is actually "Viscousity Index" which is measured over a range of temperatures.
Scientifically speaking, raising the temperature doesn't alter the viscousity index [even though flow is vastly improved ]
The flow is measured over a range of temperatures and is then rated with a viscousity index.
