You're 'history/teaching' on cold start protection

When my dad first came to Canada in 1970 from Australia, he knew that keeping an engine warm was the key to getting it to start in cold weather.

He had a block heater on his 1967 Mustang that was always plugged in in the winter; and he kept a large, orange extension cord attached to it and wound around the grill, so he could use it wherever he went. In the dead of winter, he also brought his battery into the house almost every night to keep warm.

His next two vehicles - a 1978 Malibu wagon and a 1991 Toyota Tercel got the same treatment, except the battery stayed in the vehicle. When I started getting interested in cars and 'helping' with them, I would often plug in the car at night, or unplug it in the morning in the winter. I will admit there were a few instances of someone forgetting to unplug, and backing out with the cord dragging behind.

My father always stressed how important the block heater was - he'd get REALLY worried if for some reason the car wasn't plugged in on a cold night. He'd cringe if he had to start it like that, and it cranked slowly. He always went on about how hard that was on an engine, and how you need to keep the engine warm to protect it and have it last in the winter.

He never mentioned synthetic oil, or 'winter oil' at all. As far as I know, he just used basic dino in all his cars. I have no idea what grade or brand he used, as he had it changed at a garage/dealership. I'm assuming his cars got basic 10w30 or 10w40 conventional most of their life.

When I started driving, either my first cars didn't have block heaters, or I was too worried about backing out with it still plugged in, but I never got in the habit of plugging in my cars, even in the coldest of weather. I always used a conventional 5w30 oil; and my cars always started up, with one or two exceptions. My dad would have been SO disappointed!

I've never used synthetics or 'winter' oils in my cars. I always thought that syns were for special, high-performance or newer cars, and you just didn't spend the money to use them in older 'beater' cars.

What made me think of this is that I've reversed course, and have started plugging in my 2002 Cavalier in weather below -10C, just to ensure the car starts. It always did before, but now that it is older, I want some extra guarantee. I still don't use synthetics in it yet, but I've found a dino that has the same properties as syn (PC 5w30), so I still haven't spent the money on them.

So, if you live in a cold climate, what was you 'lesson' or 'example' on how best to get cars to start cold? Were you taught about synthetics, heating devices, or both? Have you followed this pattern the whole time, or have you changed you game plan?
 
I was taught not to let it get cold! Put a few layers of carpet and carpet pad and a tarp over the whole front of the car while the engine is still hot from driving, and the next day you'll have no problem! In general this does work, even in sub zero and windy weather.
 
A minimum of 5w30 oil and a good fresh battery. That and making sure the engine is in a good state of tune. The lowest I've started my Corolla was -15F, but I've started out other vehicles, particularly our 98 Blazer, at well below -20 at our cabin in the CO rockies. I never experienced a no start, but below -20, it cranks REALLY slow.
 
I'm betting we will hit -10 to -15F tonight. My car looks like it's sitting in a snow bank currently! Glad I have a brand new Autolite Titanium battery. I might head out in the morning to do a Dave Rock cold start!

Because of his extensive protocol in keeping things warm, he was able to slip on the oil and do just fine. If you had gone to a hockey or American football game parking outside, his oil could have made things tough when it was time to leave. Batteries over time have recieved more capacity and cold cranking amps as cars have so many more electronics these days. This helps on the starts. I've spent a few xmas in the cold, and they used plug in devices and 5w-xx conventional oils. Again in the last 20 years the 5w-xx probably kicks the 1970-1980s oils butt in base stocks and pour viscosities as well. It think it's better today from every angle.

Buy the most expensive battery you can is the only advice i was told. It can make up for the "wrong oil" in a trying situation. Again starting a car at home even in a cold garage isn't nearly the same as out in the elements somewhere.
 
i have used both conventional and synthetic 5w30 with the block heater, never really noticed a difference in oils in a cold start, The block heater, i use all winter set on a timer for two hours. What i really like about the block heater is the engine warms up much quicker, another thing i like on cold starts with the block heater is the engine does not seem to race has hard as it does when not plugged in.
 
These days I have a huge battery, AMSOIL Signature Series 0w30, and all systems in good condition (electrical, fuel), and have no trouble starting even below zero.
 
Maybe block heaters are this amazing thing, but they won't be around to help after the car sits overnight somewhere besides my garage, which it does when my wife works third shift, or we head somewhere for the weekend, or my car sits in an airport parking structure for a few days.

On the other hand, a thin "winter oil" and a good battery are there all the time... and less hassle to boot.
 
I guess I never had a "lesson" on cold start protection. Growing up we never plugged anything in.. don't remember one that had a pan heater. Never ran any special oil either. Parents or any family members never had a vehicle die from it. Don't remember any not starting either had a few that wasn't drivable in snow though.. E350 van I think it was. But I grew up and still and live in Missouri it may not matter. To this day I don't do anything special. I run bigger batteries and thinner oil with a little MMO.. starts right up regardless of temp.
 
My "lesson" hit at -7'F in my mazda 323 when the starter made 1/4 revolution and died. Used whatever conventional 10w30 or 10w40 my Dad's mechanic put in, 1997 era.

That motor was pretty tight, roll started it in 2nd gear and the clutch slipped, should have used 3rd.

My only concession is a magnetic oil pan heater when it's below -10'F just as a belt-and-suspenders thing. I also do all sorts of tricks to my house when it's that cold to keep the pipes from freezing. Don't need too much grief when it's that cold, not the time for experimenting.
