yet ANOTHER NOOB question.

TARDCORE · 01-07-2010, 09:33 PM

On a cold start, how long should I wait to drive the Z. On my RSXS it would rev to 2K rpms and I would wait until the revs went down to about 1.2k rpms to drive it which is also when the oil temp gauge would register. On the Z it does not rev high at cold start nor does the oil temp register even after a few minutes. Sorry if this has been asked before but the site takes to long to search with the construction.

I let mine run for 2 min or so - at start the car revs over 1k rpm (1200 or so) the settles down to around 800. As soon as its died down, I'm on my way.

Its been really cold here in Florida for the past week or so, I've got the timing down almost to a science. Warm up the car, drive to the stop sign at the corner, and the heat clicks on.

Red370 · 01-07-2010, 09:45 PM

no need to at all, start it up, and git er done.

AK370Z · 01-07-2010, 09:49 PM

This is what I do:
Start:

Warmed up (my way)

I start the car. Wait for the water temp DOT to move from first to 2nd and then all hell breaks loose

. I try to warm up a little before driving away because I live 30 seconds from highway and temps drop below freezing for 4 -5 months (like now ). Don't feel too comfortable flooring the car when the engine is cold. But if I'm driving to the city and forced to drive cold (unable to wait), I just shift rapidly and keep the rpm less than 2000 until the engine warms up.

But I will say this, these newer Engines are designed to drive cold without a issue/problem. I was told, in old engines, most wear and tear happens during the first 15 minutes of driving a cold car. But with these new sophisticated engines, I think that's changed. As an old habit, I just feel comfortable driving a warmed up engine.

thanks guys! I think I should start a thread called "TARDCORE'S TARD QUESTIONS" maybe people are thinking the same thing but don't want to ask. haha like they say in school.

VCuomo · 01-07-2010, 09:54 PM

I usually wait for about 30 seconds or so, then go. But I don't do any real revving until the oil temp is at least at 150 or so.

I'm going to have to say no to engines that are designed to drive cold without an issue/problem. It is never good to drive a car especially a sports car from a cold start... ALWAYS warm up and go.

Don't look at the water temp "dots" as that means diddly squat as the water doesn't protect your engine, oil does.

You can drive it straight after starting, but gently until the oil temp gauge is at least off the bottom so the oil temp is rising. I wait till a solid 150-160f before punching it which is about a 4min drive.

I know but I use it as a timer. If the temps freezing below like now, it takes 3-5 minutes. In summertime, 2-3. By the time my oil gauge even moves, I have probably did a few 7K shifts already since I live 30 seconds from highway.

UNKNOWN_370 · 01-07-2010, 10:22 PM

I drive g37 coupe but I let the rpms regulate to right under 1000 rpm. About 2 to 5 min depending...

m4a1mustang · 01-07-2010, 10:39 PM

I fire it up, sit for maybe 30 seconds, then get moving. I keep revs down and refrain from any aggressive driving until I see 180F on the oil.

azn370z · 01-07-2010, 10:59 PM

The manual says let the engine warm up for 30 secs before driving.

Anyone notice that at start up the exhaust is somewhat loud for about 20 seconds then silence, The exhuast doesn't make a sound until the next time I start it up again.

m4a1mustang · 01-07-2010, 11:25 PM

Yes. The ecu bumps the idle up to help warm the car quicker and get fluids pumping. It's all common sense, really.

Thats pretty reckless - when the car sits for a while, a majority of the oil up in your valvetrain has slowely gone down to the pan. The potential to cause excessive wear will be at its highest on a cold start.

I'd always recommend waiting til the RPM's drop past 1K at the least.

I dont baby my cars. I HIGHLY doubt any damage can be done by not allowing your car to warm up for a specified amount of time, especially with modern day engines. Start the car, keep rpms below 4k until oil temp reaches around 180, then drive it how its meant to be driven. You didnt rev your engine above 4k for the first 3,000 miles did you?
