Is it best just to leave it running for a while or push on the gas emmediately?

All top experts in the auto field now say there is no need to warm up an engine. The oil is flowing fine within seconds of startup. The rest is just old school. You can check with your dealer or the manufacturers website.

I have been told you don't have to let it warm up but let it idle for about 30 seconds and don't push the gas petal down too hard (like you're in a big hurry) for several miles. I have been doing this for years with three vehicles and I have never had engine problems by not letting the engine warm up for several minutes.

No it is not! In the distant past when only straight mineral oils were available and engine materials (mainly bearings and cylinder walls) wore quickly until oil circulated freely, then a short idling period was beneficial.
However, with engines built from modern materials and the universal use of highly advanced lubricants, engine idling is simply not necessary.
Indeed, if you read the handbooks of many modern cars they tell you to drive off immediately you start the engine to ensure rapid oil circulation and warming up of the engine.
Of course, no one is advocating that you should start the engine and then accelerate away like a lunatic - just be sensible and you'll notice the temperature gauge of your car will soon indicate 'normal'.

WHEN A CAR SITS ALL NITE THE OIL DRAINS TO THE OIL PAN. SO WHEN STARTING A CAR LET IT WARM UP FOR A COUPLE OF MINUTES TO GET THE OIL GOING THOUGH THE MOTOR. MOST NEWER CARS HAVE A COMPUTER SYSTEM THAT WILL TAKE A LITTLE TIME TO GO INTO A CLOSED LOOP. CLOSED LOOP IS A FUEL MANAGEMENT SYSTEM FOR YOU CAR. ONCE THIS HAPPENS THE COMPUTER DOES THE REST. STARTING A CAR COLD AND PUSHING DOWN ON THE GAS HARD COULD DO DAMAGE TO THE MOTOR.

No, they don't need to be "warmed up". And "Old School" was really only to run a minute or two to ensure oil pressure and lubrication. Get it started, then drive reasonably. That's what Dad taught, rest him, and it's what I'll teach the grandson in a few years.

The car should definitely be warmed up. This is to allow the engine oil to circulate through out the engine. Specifically it will virtually eliminate engine wear through the upper portion of the engine. The lifters and valve train will get sufficient oil to prevent wear.

Let it warm for a few minutes to allow the oil to circulate before driving off. That will add years to the life of your engine.

no its not true and actually harmful. just get in it and drive. modern cars are equipt with all kinds of devices and sensors to allow for normal operation during warm up. allowing it to idle for no reason cold is harmful to engine bearings and the inviroment

yes, just let it idle to warm up. It's not just about oil flow.
Rapid heating can do things like blow head caskets, crack a head, warp a head, etc.

let it warm up...even if it is a new car...it is warming up more than the engine
