Yeah, me too, it's always been that way, never gets any worse or any better, except for temperature effects on oil flow at startup.
I don't pay any attention to it. I do let it idle for a couple of minutes before driving away in cold weather, but that's just habit, I've always felt you should do that...with any car.
Had a co-worker who lived right on the highway on ramp, and he'd always just jump in the car, late for work and hit the highway going 75 within a minute and a half of starting the car.
One particularly bitter cold day about 2 miles from the house he blew EVERYTHING outta the gearbox, shafts, gear clusters and all. The case had metal fatigue and apparently couldn't handle the extreme temp changes along with forcing glacial thickness gear oil around at those speeds.
Everything that came out of it was heat scorched blue and black. That was a Nissan Sentra with about 65,000 miles on it, way to early to have a disaster like that.
It was one of those wonderful "I told you so" moments, as he and I used to go 'round and 'round at work about the benefits of letting a car warm up before driving it hard.
He always had the assertion "as soon as the idle drops, it's ready for anything" and "maybe if you quit driving domestics, you wouldn't have to baby your cars"
Some never learn. He bought a Civic SI (to replace the Sentra), and asked me about break-in period. I told him how I choose to do it, varying speeds on the highway, working up to higher speeds and harder acceleration over the first 1500 miles or so.
The salesman (THAT's who you want to listen to, right?) told him no "just drive it normal for the first 100 miles, then drive it like you stole it.", which he did.
Last I heard at 38,000 miles it was using a quart of oil every 1200 miles, and he wanted Honda to fix it, but they say it's not within criteria for 'excessive consumtion".
