[stewie]

Honda recommends not warming up your engine. Just get going but keep it under 3-4k until you reach normal operating temp

mm yeah, I've never heard a honda mechanic encourage warming up a Honda by idling. And taking it easy on the engine until normal operating temperature is pretty much a given.

kant get vtak wen teh vtak-oil is c0ld

yo if its cold out, I'll start my car a half hour before I think I'm gonna leave. I want my fucking seats toasty when I get in it. Screw a cold steering wheel.

I start a fire under my engine. Warms up shit quick.

2 munites is what i let mine warm up MAX...after that i'm just wasting gas.then i dont go above 2500 rpm till i'm near operating temp.[b]the oil in your engine warms up faster than your coolant does, so keep that in mind [b]

Go tell the guys over at www.bobistheoilguy.com that.
While there, ask them about the yhearly oil changes some of 'em like to do.

If its just me, i usualy wait untill the car it ar normal operating temp. or if there is people with me untill the needle is above the C line. I also keep my heater to cold and have it off. My engine takes forever to heat up, maybe is bc there is nothing in there to retain the heat and all of it gets lost in the wind.

Reason i warm it up soo much is the tranny. I know the engine oil dosent need that much warmth to thin, i just dont wanna drive with he tranny cold and have hard/cold shifts

Driving the car with cold tranny oil isnt bad. Its just a bit notchier but fine for the most part. At least thats how mine is.

[JaK FRoSTWhiTE]

In the owners manual on a cold start it says to let the engine run for 1-2 mins before going.
Then just drive slowly until the needle reaches the middle "operating temp"

You can eliminate the granny shifting by just letting it warm up a couple extra minutes longer. Its also been debated over and over that cold starts is where most engine wear occurs.

Thats pretty much the focal point for the regular oil vs synthetic oil argument. My main reason for warming up my nissan for 20 years is because I want my ride to be fire before I take off when its 10 degress out and it takes 2 decades to heat that interior up.

[bcjammerx]

the warm up myth might have been perpetuated due to obd I O2 sensors and open/closed loop running. You won't hurt anything by driving with O2 sensors that aren't fully warmed up though.

As to engine wear...once it's ran for a few seconds...yeah the oil is circulated fine. Don't rev right at startup...like right when it turns over that is...if it sat overnight.

I don't rev my engine or drive hard until the O2's warm up (closed loop)...but that's just me...don't really have any reason to do that other then the ecu is adjusting fuel via sensors...whereas in open loop it is just using pre-programmed data and doesn't take into account actual air temp etc etc...again...no proof that it is harmful though...just my pers. preff.

If it's ubber cold I let it warm up the coolant...but that's just so I won't be cold in the cab...no

I see most of you are from the State's... but up here in Canada, (The Maritimes especially), it gets pretty chilly, like -20, -30 Celsius, and even lower than that. (That's downwards of -22 Fahrenheit). It's pretty much necessary to let your car run for 5-10 minutes or more before going out in the winter, and it's not just so that its easier on your motor. Half the time the window's are frosted or foggy on the inside as well, and you need the warmer air to get rid of it. It's also not uncommon to see revs of between 2 and 3k RPM on a very cold start.

But i agree, i always go easy on it until i can see the needle start to rise, which sometimes, the drives end up being too short or too cold for the motor to warm up to running temperature before being shut off again. My college is only 4 kilometers from my house... so sometimes it actually ends up warming up longer than the drive itself
