Do you warm up the car every morning b4 driving?

[sshole]

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

Every. Single. Time.

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

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.

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.
