Default Letting car warm up

Do you let your car warm up especially in the colder months ? If so, is your motor built ?

How long ? I am letting my coolant reach 180 (this is after stock gauge shows). Unfortunately don't have an oil temp sensor.

Running 10w40 with forged bottom end.

Search for the 9,275,882 threads about this. The standard method is to get in the car, start it, put on your seat belt and drive sedately for 5 minutes or so.

BMW used to use almost those exact words (1981 320i).

Sure.....don't start the car and run on the rev limiter in 1st for 10 minutes.

Oil takes 20 minutes to get to temp driving, by the way. (just getting ahead of that argument) so if you don't plan to move till oil is up to temp, set an hour aside idling.

people clinging to this carburetor age nonsense is exactly why some municipalities have passed laws banning this moronic practice.

but then again, manufacturers designing to people's NEED to be perfectly comfortable at all times got remote starts practically standard on everything new

Idle for 30 seconds after you start the car. Drive conservative under 3000 rpm until fully warmed up.

Letting your car warm up that long is wasteful to say the least. I let me car warm up for maybe a minute and do as the others advised and drive conservatively until up to operating temp.

I warm it up enough for the heater to kick on. Warms up quick as long as you are nice to it.

Why you shouldn't let it warm up for more than, say 1 minute, beyond being incredibly wasteful.

Aside from not "getting on it" until the temp gauge is where it should be... there is no set warm up time.

Sometimes I start my car and let it warm up when it's butt cold out... but I don't care about what happens for those handful of times. I'm more concerned with the ice on my windshield melting, or my butt not freezing.

Me personally I give my N/A 2008 impreza warm up for 10-15 min in the winter. In the summer I still wait 4 minutes or so before taking off. My other car is POS (but new) Mitsubishi mirage and it sounds and feels horrible if you don't let it warm up a few minutes regardless of time of the year.

I let it idle until temperature gauge hits the 1/4 mark and then drive normally, shift every 2000-3000 rpms until engine is fully warmed up

I usually have it in gear while starting and am off and rolling while the starter is still spinning . No need to wait. I do keep boost below 5 psi until oil hits 180, then WOT every day (multiple times daily). In 21 years of driving many different makes and models, no issues.

Heck, why bother with the starter at all? Just park it on a hill, let out the clutch from a roll and off you go!

I do let it idle for about a minute if I'm running E-85 in cooler weather.

A video on the subject from a couple years ago. Dom knows a little bit, which is 100 times more than me, so I let our cars warm up.

Start car, put on seat belt, check mirrors, put car in drive or reverse, keep under 2000 RPM for 2-5 mins depending on weather. No need to slam on the gas or rev to limiter.

I look at the clock when I start and wait until the clock goes up 1 min. So the most could be 60s the least could be 1s. It’s pointless I know. Just drive like grandma the first 5 min or so.

well 100x's zero is still zero right?

That guy is a moron making a video of why in 2019 you still need to let a car sit and putter for 20 minutes before driving.

Next he'll explain why leaded gas is a necessity.

This ↑↑↑

After scratching a few windshields, once using even a brand-new ice scraper, I gave up using any ice scraper on any car. Handed that job over to the heater-defroster and the windshield wipers years ago.

At least these days, neither of us is under any schedule but out own, so it doesn't even have to be a daily occurrence.


I don't use the engine very hard until the claimed oil temperature is at least 160°F. Small amounts of throttle and not much over 2500 rpm. Sure, I sometimes end up waiting a little longer for a bigger break in traffic entering a main road. But having a little patience when driving isn't a bad thing.

10ish minutes in the winter. Then I baby it as much as possible until oil pressure and coolant temp are right. And then I'll wait at least another 10 minutes before getting on it (if need be).

When I hear a guy talking about how in 2019 you need to let a car sit and putter until the oil is warmed up (takes 2 to 3 times as long as coolant, which would be a solid half hour in winter) I call it like I see it.
So no, Dom doesn't know things, he regurgitating baseless internet myths.

Mind boggling people are still taking that position these days.

Do you still have a long distance plan on your home phone?

Easy, buddy.

The video explains Dom's point of view that letting your car idle will not damage your engine, as was/is the opinions of many others. And while he does touch on the viscosity of oil when it's cold and the ecu enrichment under load when the coolant temp is cold, it's not a debate video, as you are perceiving it. He is saying that if you want to let your engine warm up, go for it, as it isn't harming anything as many of the "baseless internet myths" you speak of would like you to believe.
