1500 rpm when starting car

[Mattc2014eco]

If I need to leave in a hurry is it bad to jump in and go before the rpms drop? I feel like I'm driving my 86 escort w the carburetor. Gotta sit a min before taking off out of fear of ruining my trans. Thanks in advance

It's best practice to let the engine warm up before you drive hard but in emergencies sometimes you don't have a choice.

I would definitely wait in cold weather. It does it when it's not cold outside also but not as long. Just wondering I the cvt trans can handle shifting into reverse or drive at 1500 rpm

In These new engines it takes about 30s for the oil to reach the head of the engine so it can start lubricating the valves. But it's always best to let the engine warm up before moving.

That's false on modern cars, for a few reasons.

1. The engine takes longer to get to operating temperature when idle.
2. Engines are machined to greater tolerances which allows them to hold a good seal even when cold.
3. Engines now have anti-drainback valves so the heads don't initially starve of oil.

Warming up an engine before moving was needed in the 60s; it hasn't been needed for the last 30 years now.

It'll be fine. 1500 rpm in neutral is barely touching the butterfly.

Yup you're right. I recently opened up a valve cover off from a 2008 corolla and does hold a good amount of oil on top of the cams.

I just wait for the RPM to drop after the first 30 seconds before taking off. Personal preference thing I guess, but it's just for the cat warmup phase.
