i usually wait about 2-3mins but if i'm in a hurry i wait about a good 1min...

Yea unless it's so cold you need to scrape ice off your car before you go you don't need to wait more than a minute after starting your car. Of course if you had to scrape off ice that'd probably take up all the time you'd use to warm up the car. But it does say somewhere in the manual that driving is the most efficient way of warming the car up.

my car runs way rich if i drive it right away. My gas mileage is better if i let it warm up for 2 mins.....only during winter. Summer is get in, start, seat belt, go.

When it's -40*C, you definately need to give it a few minutes to warm up. The needle doesn't leave cold in the ten mintues I let it run. The vibration and stiffness of everything is also really, really bad. The summer is totally different though. I just hop in and go and take it easy until everything is good and warm.

Why are people saying you have to "let the oil circulate". The oil is everywhere within seconds after the start-up in a honda. Hence you oil pressure light turns off after two seconds, because oil pressure is good and oil is at all the critical places it needs to be. You don't have to let your car warm up or the manufacture would make a note of it in the owners manual. Its for older carborated cars that warming up is nessecary. If anything it just wastes gas!

I would only let my car warm up completely if I drove an evo or an sti, being I own neither nor a turbo car. I could care less.

Why is this even a thread on this site, use common sense...if your engine is ice cold, don't drive it hard. When its up to temp..go beat on it all you want...why did this even get to 2 pages.

I agree with letting it run for just a sec, but keeping the RPM's low until its warm. when you start it up, the oil is cold and therefore thicker, so if you rev it up cold, even after oil is circulating, It wont lubricate as well and doesnt always do a great job of getting in tight *** spots.

At low rpms thats not a big deal but people who rev cold, overtime, can get bad spots on bearings and places with tight clearances because of oil being thicker and not reaching everywhere at the cold higher RPM. I just usually give it 30sec-1 min and take off nice and slow till i start hitting temp.

When its really really cold outside, I like to start my car & hold the accelarator to the floor for good 12-17 seconds. This allows me hit the rev limiter extremely fast allowing me to test the engines condition while making a really loud noise. All my neighbors leave cookies & yummy pies on my doorsteps for the holidays.

I always let my car warm up but it's easy for me since I start my car while sitting here talking on honda tech thanks to remote start

HatchSpeeD

YES! I also like to start my car with a remote starter but I all.....ways make sure i'm parked really really close to someone & the car MUST be in gear. Not only does it get nice and warm before I get in it, it allows me to determine the quality of my bumpers.

warming up your car is important i think. its just to get the cat warmed up and help reduce emmissions. i warm mine up for like 3-5 min before i drive. when oil gets hot it has more pressure. there will be people that will argue, but anyone that has a vtec engine would know. if you dont warm up your car, vtec will not engae beacause it relies on oil pressure.

another reason to warm up your engine is so you dont get piston slap. metal expands, so the hotter the engine gets, the better your combustion will be.

That is my opinion

The engine warms up quicker while driving, which would reduce emissions rather than having it take longer to warm up. And VTEC is also dependant on coolant temp, so you cannot just say that the warming up and oil pressure is what stops it from engaging. You could have a billion psi and VTEC would not engage on a cold engine.

only reason i ever do it, is if its freezing outside .. but im always running late so when i hop in, off i go

A guy on my forum recently used his obd2 scangauge to look at fuel usage depending on engine temperature.

Idle Warm Up Experiment

The basic conclusion is that the engine is VERY inefficient while warming up. You're better off driving your car during that time period instead of letting it idle. Not only will it warm up faster, but you're going to actually be USING the gas.
