how many of you guys get your car to warm up first before you drive it in the morning

albertgunit101 · 09-06-2007, 01:56 PM

i just want to know if there are a lot of number of people who do this. and if its really important. coz everyday i always drive off immediately after i start my mr2. so, is waiting for the engine to warm up before driving really that important?

Luni · 09-06-2007, 02:24 PM

I just drive it.

I drive it nicely until its warmed up then I go for it.

I figure it is just as much stress on it to warm it up slowly cause while the engine is cold, the rings arent seated as well, and the oil isnt lubricating as well. So I figure load helps warm it up quicker, and makes it better overall. I never let my cars warm up. I just drive very nicely until they are warmed up. Then boost boost boost.

I do the same thing too... I just wait for the blue smoke to clear, then I go LOL.

At the first start in the morning, I let it idle for a few seconds then pull out. Everything will get to operating temp much quicker if you drive it. So take it easy until it fully warms.

TomsMR2 · 09-06-2007, 02:45 PM

once the oil light turns off, its redline time!

you should start your car and drive casually to warm it up. like sang said, it actually warms up faster and causes less wear. you really shouldnt hammer on it until its fully warm, but driving is fine. my motor has 10K on it, so i dare it to try to break

Ben · 09-06-2007, 10:16 PM

I actually wait until it gets to at least the 1/4 mark on the temp gauge, drive it easy until 1/2, then go.

Jaicvc · 09-07-2007, 12:04 AM

MMmmm for me wait until the lights are off then drive until i hit the freeway!! then boost go all the way lol!!!

Spektrewing386 · 09-07-2007, 01:36 AM

i have a oil temp gauge and it takes about 3 times as long for the oil to warm up than the coolant...... just sayin

Hellstorm · 09-07-2007, 01:57 AM

I rev it up to 9000 rpms as soon as i start it, then dump the clutch and crash into my house

sleepermr2 · 09-07-2007, 02:00 AM

yea i always let it fully warm up. the very first start when its cold is the most wear. IMO driving it when its cold till it warms up isnt that great either. when its cold the oil doesnt lube everything as well. i let it get to normal temps then take off. ive done that with all my cars.

TomsMR2 · 09-07-2007, 02:39 AM

driving it cold is proven to be the best way to warm an engine, for this exact reason:

it doesnt flow as well.. still lubes fine

if you drive it, your oil gets to temp much quicker and does its job better, sooner.

sleepermr2 · 09-07-2007, 03:02 AM

that doesnt make sense to me. if it doesnt flow as well hows it going to lube everything just fine? cold oil is thick and does not flow as well and cant get into smaller places inside your motor until it warms up and gets thinner. this is why your oil press. is high when you first start your car and the oil is cold. it has a difficult time getting through the oil passages, splashing the the cylinder walls, etc.
drving it when its cold is of course going to warm it quicker cause your at a higher rpm and producing more friction and combustion heat as well will heat everything up. now think about it, when your driving with cold thick oil at a higher rpm and its not "flowing" as well and getting to the top of the head and flowing back down quickly, you think thats not putting any wear on the motor? i think so

i see where your coming from but driving it till it warms up at higher rpm is going to put more wear on the engine vs. letting it warm up at a low idle rpm.

TomsMR2 · 09-07-2007, 03:10 AM

its putting less wear on the engine than having cold oil in an idling engine for an extended period of time.

cold oil still lubricates. load is going to cause damage.. low load (low throttle angles) and moderate rpm puts very little stress on a motor, but generates more heat than idling. the key is to not load the engine heavily.

sleepermr2 · 09-07-2007, 03:19 AM

like i said i see where your coming from. when your car is cold it runs at a high idle anyways helping everything heat up. cold oil of course lubricates, just not as well. load is load, and even at moderate rpms the oil cant get to everywhere it needs to be thus causing more wear.

Lachrymal Cloud · 09-07-2007, 09:11 AM

Good thread, good question. Help me out with this one. My new 93T REQUIRES me to warm it up. This is my first turboed mr2/car and I thought this was normal but reading this thread seems to suggest otherwise. My car literally takes about 3 full minutes before I can drive it normally, not boost, drive. I just runs like hell and dogs out any earlier than about 3 minutes as if it's not even getting gas. Is this a major issue I should be concerned about? Also I have an HKS turbo timer I set to 60 seconds (it came with the car) and I'm pretty sure this timer does the obvious which is keep the engine on after taking the key out but this wouldn't cause the above mentioned situation would it? I've had my car for about two months the last 5 weeks of which has been in the body shop so I haven't the ability to get it mechanically checked out.

it certainly gets everywhere it needs to be. its a matter of flow, you need higher flow to combat higher load wear.

Bob Is The Oil Guy

theres been lots of tests done. dont have to take my word for it

Luni · 09-07-2007, 12:07 PM

Yeah, I mean what warms the engine up faster? Idling, or actual driving? Driving creates MUCH more heat energy from friction. As its creating heat energy, its warming up the oil faster, and its lubricating everything better and flowing better.

Makes plenty of sense to me.

NOT to mention, warm your engine up, but you arent warming your bearings and transmission up, so when you think its good to go from idling it to warm, the tranny and differential and bearings are all cold. Then you decide to be smart and go balls out on stuff that isnt warmed up.

Warm it all up at the same time.

sleepermr2 · 09-07-2007, 05:56 PM

well agree to disagree

Luni · 09-07-2007, 07:47 PM

Sure, the experts dont know anything, and its your car.

So yeah, I guess we will have to agree to disagree.

TomsMR2 · 09-07-2007, 07:48 PM

its kind of a proven fact, but you're free to disagree. if you idle your engine to operating temperature, your oil is still cold.
