In the past couple days where I live, it has been cold. Very cold. The kind of cold that sends your nuts into your body. The kind of cold that freezes spit before it hits the ground. The kind of cold that... alright you get the idea. Last night The ambient temp was -33 Celcuis or about -27 F. In the morning my car did not want to start. I had to crank it over a good 3 times before it started. I was wondering if anyone else experienced this and is there anything I can do? I have to park outside, and my car didn't come with a block heater. I was thinking about a gas line anit-freeze but I'm iffy about putting additives in, as it says not to in the owner's man.
Besides a block heater, are the additives worth it? or safe at all?
