i never warm mine up unless its cold outside.....just so the heater will be warm

My car is in a garage.

It warms up while I walk down for the paper, less the 2 minutes. I always wait for the RPMs to settle to avoid the D5/R tranny clunk.

When I parked outside with snow and ice it would idle until I got the windows clean. Then I would restart the car before driving.

As far as I'm concerned, Idling is bad for emissions and fuel consumption. Use high quality oil, follow your maintenance, it won't hurt anything.

anywhere from 5-10 minutes. I have remote start, so I crank it up so it gets to operating temp. I do this to get the interior temp right, engine warmed up a bit, and get my compressors running to fill the airtanks (if it's been sitting for a few days they will need to be pressurized).

I always let my car warm up for a few minutes. Idling isn't going to cause damage to the engine. It's cold starts and heat cycling that kill engines, not idling.

My dad was in the military for 25+ years and worked field for nearly half of those years in the Army Corp. of Engineers. He insists that everyone in the family warms up their cars. I wonder where that habit came from. No offense, and with all due respect, I would rather take my dad's word. My '97 Tahoe that my dad and I took care of together was ALWAYS warmed up prior to driving. Even on summer days, I always let it idle for at least a couple of minutes.

The end result? 130,000 trouble-free miles. The only things that were replaced were spark plugs and the serpentine belt. Cylinders compressions were still good, everything running right, etc. She started up on the first turn of the key every time, until the very morning we traded her in.

Manual states (at least for the '03 TL, I don't know if other years are different) that warming up your car isn't necessary and that cold engine consumes more fuel. Bingo. That's all they say. I've read the manual. Our cars are supposed to be "green" cars. They don't care about your engine once they sell it to you. They want to see their cars yield maximum fuel effiecieny wherever and whenever possible for good PR. Not to mention Honda engines usually last a long time, so it's not like a little bit of cold starts and heat cycling will kill it in 30,000 miles, anyway.

Let's see...
My car has been sitting outside overnight (no garage here at school) in typical Michigan weather. Last night, for instance, dropped into the 20's. Engine start. Idle revving at 1300-1500 (usual upon a cold start). Shift into reverse; bang, shudder, car jerks. Oooh, that's nice. I wish I had warmed up the car now. Back out of the driveway fast because the engine is idling fast... must use brakes. On to the street, stop, shift into Drive, bang shudder, jerk again. Ouch. Must be doing wonders to my already-pansy-ass transmission. Off we go now. CAI hissing like a pissed off snake, engine sounds loud and uncomfortable, still freezing my butt off because the engine is too cold to blow hot air and the bunwarmers aren't up to operating temperature yet. Shivering, shivering, shivering. After about 5 minutes of cold driving, everything finally gets warm. Whew.

That, or let my car sit and idle for a few minutes? I think the answer is obvious.

never warm it up Unless it sits for a few days.

Common Sense (rare these days) would say that oil takes a little while to circulate throughout the entire engine after it's started cold - even for these "modern engines". It certainly can't damage an engine to let it idle for a couple of minutes before driving car. I'd like to know where this bonehead idea came from; never warming engine up for a least 30 seconds or longer.

Just for reference.... a friend of mine has a repair shop and he says since the installation of remote starters, way more people are coming in with bad O2 sensors. Coincidence? It is not good to idle your car for long periods of time. Remote starters (I have one on my truck) have a 15 minute shutoff built in. The only time you really need to give it any warm up time at all is to get the heat moving and when it's sub-zero. It warms up faster when you drive it. 30-45 secs and then drive off slowly.

Ok.


I've read both arguments for and against this.

Is there any other source other than what seems to be a manual with no evidence, ad military engineers that we can all acess for this info?

i've done a search and came up with nothing but highway mpg on the cl-s.

anyone?

I let mine warm up for about 30-60 seconds. I don't rev it above 3500-4000 rpm until it gets up to operating temp. It's about 2 miles to the highway, and then a slow merge. Once it's up to temp, it's fair game.
