That's true, it does require 120VAC. However, the only time I really needed to plug mine in was overnight, and I was normally at home, so finding a place to plug it in wasn't an issue.
For some, the thought of draining the cooling system isn't appealing just to install one of these units in the lower radiator hose. I did it to give my motor some cold start relief after it sat overnight under frigid temps, and a much quicker warm-up.

Regarding the earlier post about mixing 5w30 with some 5w20 for cold temps. That isn't making any difference on the cold end. Would be a little thinner at operating temp. To get thinner at cold start temp would require mixing with a 0w30.

Will it make a big difference at 1/3 of the total oil volume as I mix it? No, but a 5W-20 will flow better when cold vs. a 5W-30... Even at room temperature. The "5W" number is not an absolute value. Just like a 10W30 will pour better than 10W40.

That's backwards. In "winter temps" (not specific other than that) a 5w20, 5w30, 5w40 etc. are all comparable in flow. 0w anything would flow better, 10w, 15w, 20w anything wouldn't flow as we'll. The second viscosity number (without the "w") is rated at a specific temp which is 212 degrees. The higher number indicates thicker viscosity, but at high temp. This is due to polymers that expand when heated. Not trying to be difficult, this is just something easily confused.

I used to run 15W40 in all my gas vehicles due to the high zinc content. After watching a few videos of how poorly it flows during winter start up, I've switched to 5W20 and add zinc. It's often referred to as engine break in oil.
