Gave the article a quick read. Verify which part, specifically? Start and drive, right away? Idk about newer vehicles, I'd check the owners manual for those. But older, I'd let it warm up, at least until the antifreeze cycles. Idk about anyone else, but I wouldn't start and drive simply cuz of being inside a cold vehicle. Specifically warming up an older vehicle with a carburator: depending on the engine size, I used to hold the throttle at approximately 1200- 1500 rpm to warm up. (I've done this with fuel injection vehicles, too. Just creating a load on the engine to make sure it doesn't die.) In the fall, do a general PM on the vehicle. Check the battery. If it's questionable, just replace it. You don't want to be out changing a battery in the cold. Even as quick of a job as it is, it can be a miserable job. For less than a hundred dollars, just swap it out
Car batteries are like $250 these days.
I just looked. Consider me shook to the core. (Talk about sticker shock. Been at least two years since I've bought one.) Cheapest I saw is 140. Unbelievable.
I paid around $110 for an EverStart MAXX at Walmart about 6 months ago. 800CCA.
I got one of those and it lasted about 2 years. The old battery was toast at 3am when I used to leave for my shift, and wal-mart was the only store open because it was on the border of the hood where I live. When it crapped out, I replaced it with a quality battery from O'Reilly's and that one's been great.
