How long should I warm up the engine before let the car go in the morning?...??

Thx in adavnace...!! :D

 

u dont have to wait for the car to warm up. its just a myth.

u can drive it right when u start it up the motor warms itself up while u drive. just dont be hitting high rpms and resist any unnecessary downshifts that'll put u in high rpms.

its like when people play sports or workout. do light workouts to get ur msucles warmed up. dont jump right into lifting heavy weights when u just get to the gym.

i've always started up my car and driven it right when it started up. never had a problem with it.

 

Ok...I know it now...thx EKtheory...

PS: my english not good..sorry..:D

 

ur english is good enough to understand thats all u need

 

Yup you got it! Idling is actually more harmful for the engine than just starting up and going!

 

Honda recommends 30 seconds. The S2000 has a built in rev limiter to ensure drivers do not go past 6k before the engine is sufficiently warm - that's confirmed because I hit it once =P

 

i wish i had an s2k

 

Where did you find this recommendation?

 

Believe it or not I asked a mechanic at Type One.

 

Yeah. Its usually 30 seconds. Toyota is the same. By the time I take my sunshade down and put on my seatbelt the car is ready to go.

 

This would be regarded as an unofficial recommendation as it is not mentioned in either the owner's manual or the service manual.

 

i'd say at least 2 minutes.

and i disagree on just starting it and going being worse then letting it idle for awhile. piston slap and mucked up cylinder walls aren't made by magic.

 

Any intentional warm up time is just a waste of fuel. If you do regular maintenance and drive normally without revving to high rpm when the engine is cold, the engine will be fine.

 

I've been warming mine up until the needle gets into the operating temp range.

So far very little noise or slap. Pretty quiet for a Honda. I also use Mobil1 because my valve lashed ceased opening up after switching (indicating reduced cam wear in my mind).

 

Why? You are wasting a lot of gas for no good reason.

 

no one listens to me
i think i need a picture.

 

Here's a relevant well known saying:

 

I usually let mine run just until my rpm's drop. I do this because of piston slap. 1500-1700 to 1k.

You really don't have to, just drive it nicely until it's at normal temp.

 

Yeah, piston slap is an annoying noise, but idling the engine until warm will not affect it. You would get the same result from normal driving.

 

i like that. lol

 

That's why I don't. plus I get really bored sitting in the car lol

 

Engines warm up faster under light load.

That is all.

 

Yep, you can let one idle for about 15 minutes and the temp gauge wont move, but simply driving it for about 2 minutes it will come up to operating temperature.

In the winter I will let the civic sit for 15 minutes warming up sometime, but it's not for the engine, it's for my benefit and so the windows will defrost enough so I can see. (you can scrape them too, but the wiper blades are usually frozen to the windshield until it thaws enough anyway. If the windows are clear or it's at all war, start car, drive away.

 

I feel sorry for my moderator friend from the frozen tundra.

 

Usually 2 minute and that it. During the winter times, it might be more because windshield are frozen and hard to see..gosh.. I hate winter.. LOL
