Practically nothing that isn't a proper diesel truck has one where I am, and we have pretty serious winters. Not Alaska or Alberta winters probably but still serious.
My motorhome had a coolant heater that ran on diesel. It circulated engine coolant throughout the coach with three heat exchangers in the cabin, one in the wet bay, and one in the potable water heater (which could also run on propane and electric). When the engine was running then that took care of heating the coolant and the heater wouldn't come on. When I needed to preheat the engine I could flip a switch and heated coolant would start flowing through the engine. That was an awesome coach.
Yeah OP has his head up his ass. You're not going to crack the block. Let your engine warm up before gunning it, of course. And if you have a block heater by all means plug it in, but really that's about making the engine easier to start by warming up the oil (to make it less viscous) when it's really cold so it's less of a drain on the battery to crank the engine.
[edit] By "warm up" I mean a few minutes. Once the thermostat tells the engine to lower the initially higher RPMs you're pretty much good to go.

I'm just curious how long do cars last in-50c? Do you guys start seeing stuff like excessive bearing wear or cylinder bore scoring from all those cold starts? Can't imagine too make of those vehicles make it past 100k miles
Read the link I posted dumbass. Even after having a clear explanation you're still making shit up and also contradicting yourself, so you're just lying on purpose. You're a liar for fun.

The rating of your oil will determine that. The "w" means it's rated temperature. If you're running 15w30 and it is below 15 degrees, just stay home for the day. If you're running 0w-20 and it's 5 degrees, youre fine.
[ - ] breh2 1 point 2.5 yearsDec 24, 2022 03:41:39 ago (+1/-0)
The "W" stands for "weight" or viscosity rating. 15w30 means 15w at cold engine and 30w at operating temperature. 0w20 means 0w at cold start and 20w when the motor is warmed up.
The W does stand for winter apparently but you're right that the numbers stand for viscosity.
The first number is viscosity at lower temperature (when the engine is not running) and the last number is viscosity at high temperature (engine running)
I've actually never seen a block heater. It might be a thing modern cars get, but I built all my cars and none of them had this as an option. It definitely something I would have scrounged for at the junkyard, but I haven't noticed this on any of the wrecks either. The thing about vehicles sold in areas that need block heaters is they usually get eaten by the salt roads rather than making it down South to sit in a scrapyard. All the cars at the local yard are rust free Southern cars because no one wants to buy rusty parts. I've only heard of these things being available as an aftermarket bolt on, and much like snow tires, you just don't find them in stores here.
Not weight, that's what temperature it's rated for.
No you won't crack the block that's baloney. You will probably significantly wear or destroy your bearings though. They are there to protect your crank and cam from pre-oil pressure conditions.
Nigger the number represents viscosity. The first number is viscosity at lower temperature (when the engine is not running) and the last number is viscosity at high temperature (engine running)

That's great if you think you have. Your engine might lock up from spinning some bearings and you thought the block was cracked, but that really does make no sense.
Maybe on some aluminum block Hyundai or something. Cracking happens typ8cally during extreme overheating, not lack of lubrication.
Plugging in only helps so much. Keeping your coolant circulated through a heater is the only way to truly keep your engine warm enough for a cold start with minimal consequences.
Lol you really have no idea. I've worked on everything from compact cars to some of the biggest land engines ever made. You're probably some pot belly trucker who thinks he's a mechanic. I know your type. Always assumes he knows shit because his drinking buddies told him a few stories.
When your coolant does not have the right glycol to water ratio, it might freeze and crack and engine block. If the oil would become so thick that it would cause damage like you think, the engine wouldn't even be able to crank over.

However if your oil is 15w-40 and it's 10 degrees outside, you very well may spin a rod bearing.
