Do you warm up the car every morning b4 driving?
 

I now wait till the rpm drops to about 1000 b4 driving. After I start driving, I try very hard to keep the rpm below 2500 until the water temperature is normal. Then I drive with WOT. Making this so complicated just to be gentle to my engine. I have a manual BTW.

Question is whether this is good or bad or simply does not matter? Some people start with 3000/4000 will warm up the cat quickly which is good to cat. I am quite confused. Any good theory out there?

i always wait until the rpm drops to about 1k before I drive.

I start it and let it run til it drops in RPMs after 30 seconds or so, then just take it easy for a couple minutes going out of the subdivision because there is no reason to drive hard or fast through there. I've always done it this way even in my truck i used to have. Just habit I guess

I'm with dbrandt01. That's what i've always done. The biggest thing for the motor is to let the oil get to operating temp that way it is at the viscosity that the engine was designed to perform at before driving it hard.

I wait till the rpms drop then I go. I keep things under 4000 rpm when the engine is not fully warmed up. Try to shift under 3500 mostly.

I usually wait for the idle to drop, then keep things under 3500 rpm until the water jacket gets up to its normal operating temp. It usually takes five or ten minutes for that to happen and for the transmission to start feeling warmed up.

I wish the car had an oil temp gauge.

I put on no gas until revs drop. That is very important so oil gets through the system. When temp needle is below cold, I give some constant 2k to 3k rpm until temp needle is actually pointing not 'negative' ie "off the charts" to the left. Without doing this, my brz will not shift into 2nd gear if it is cold outside.

No warm-up unless its below 0 Celsius, but I drive like a grandpa for the first 10+km no matter what to get all the fluids up to temp.

I don't let it warm up, but I don't drive it hard in the morning.

Also the car hardly ever sees anything below 50 degrees anyway.

What everyone else said, basically.

When cold, I don't necessarily wait to get the car moving. I believe some load on the engine, even when cold, is better for the engine because it increase the (oil) pressure. However, I keep it under 25 MPH and moderate RPM in any gear until several clicks up on the H-2-O temp indicator.



I do not have a problem with entering second gear as some do.

I usually don't warm up before moving as I am in a garage and exhaust is rather loud at 4:30AM in the morning for my neighbors, I try to scoot out quickly. (while keeping under 3k RPM)

I begin moving almost immediately, but drive gently below 3k until the needle is above C. Then drive normal under 4k until temp has stabilized. No redline or WOT until I've been driving 10-20 minutes depending on ambient temps.

0w20 full synthetic flows easily below freezing, but I believe idling/running at cold temps should be kept as short as possible. I want to get it warmed up as quickly as possible.

I pop-start my car at 4000 rpm every morning in 1st gear and run it up to redline almost immediately.

Every. Single. Time.

This. The best way to warm up a car is to drive it. Just keep the RPMs below 4000 and don't put the pedal on the floor until it's warmed up. Idling is worse for the car than normal, low-rpm driving, and it will take longer to warm up the car.

Waiting 30 seconds for the idle to drop is fine, but if you're waiting 5-10 minutes for the needle to start moving, that's too much.

Regarding warming up the cat, this is actually the reason for the high idle. Your cat will warm up much, much faster than your engine. It's just a piece of metal that's directly exposed to the exhaust, and it has no buffer of cold oil and coolant to soak heat, so that 30 seconds or so of high idle is enough to get it warmed up.

My warm up time depends on how fast I set up my phone and pick a song on my massive playlist. But I usually take it easy on the car when I drive off since I gotta get out of the alleys, small streets, parking lots, etc to get onto the big streets.

Correct me if I'm wrong, but this can't be good for the car. You're creating a lot of movement inside the engine without the oil properly being set up.

Nope. I'm always running late to the gym before work in the morning.

How do you think oil gets transferred from the bottom of the oil pan to the top of the block? Movement. Lots of movement = lots of oil.

It's fine. The best way to warm up a car is to drive it... but generally avoid WOT before reaching normal operating temperatures.

I usually keep my car under 3000 rpm until the coolant reaches normal operating temps. Then after it's driven hard.

Also, if you're worried about your oil not reaching temperature within the first 10 seconds of turning your car on, you should try using Unicorn Blood Oil. It's pretty pricey at $10,000/qt, but it's worth it for the longevity of my car.

Launch control out of the garage.

:word: In reverse.

I wait 10 min for it to warm up, ive noticed that the more you let it warm up the deeper the exhaust note is, (or the noise coming from the sound tube) is significantly deeper and will make a rumble at lower RPMs. I cant really explain why but ive noticed the difference from when i only wait 3 min for it to warm up the sound isnt as deep and doest growl at low rpms. Or maybe im just crazy

Yeeaah you're crazy, lol

Waiting longer to warm up doesn't have any effect on how the engine operates when it's fully warm. As it's warming up however, the RPM will slowly drop to idle speed, so in that sense it will sound deeper if you let it sit long enough to fully warm up. But either way, it should sound the same once it's all at normal temps (this includes oil temp, not just water temp)

BTW excessive idling is considered extreme conditions in many owners manuals. I know it sounds silly, but it can cause issues.

im sure 5-10 min isn't that bad i just wait for the needle to get a notch or two pass the C, but ive noticed a deeper sound when i let it warm up longer after im driving not during the warm up. And ive noticed after only letting it warm for 2-3 minutes theres less of a rumble at low RPMS when im driving. Like I said I cant really explain it, maybe ill make a video and compare to see if maybe my mind is just playing tricks

Because it allows contaminants to collect in the oil (water, fuel, etc)... that's the main reason.

Maybe I'm getting old but I didn't know people still used "b4" or those things anymore. Off topic.

I hug my engine every morning in order to transfer body heat before starting it up. Gotta take my shirt off to do it, but its worth it.

I wait 99% of the time. On that rare occurrence that I don't I find shifting from first to fourth gets the trans working smoothly

I drain my coolant to microwave it before putting it back in.

EVERY MORNING

I warm it up, regardless. Wouldn't have it any other way. So far so good.

No.

Wow, some of you folks need to stop taking your parents advice about modern technology... And this isn't a race-prepped engine that's running some exotic block without an electronic starter.

Just turn it on and go folks, your car gets warmed up way way WAY more efficiently tooling around your neighborhood at 25mph at 2000rpms than sitting in your driveway idling.

If you need more proof, just look at all the modern cars with stop/start technology that completely shut off motors at idle...

I do until the rpms drop, just feels annoyingly sluggish when I hop in it and go.

I let it drop under 1k rpm, and an additional 2-3 minutes. I notice it's alot smoother shifting and accelerating.

I wait 2 seconds and then reverse (RPMS instantly drop) and just baby it for the first minute.

yea i've warmed up all my cars in the past so i let my brz drop to 1k rpm and then go

I warm it up just to piss of my neighbors
