Engine warm up recommendation.

kimtiki · 03-02-2011, 09:45 AM

Hey there,

How long do you guys warm up your engine(N54g in the morning??

As long as it takes to start it, put it in reverse, and back out of the garage. I drive reasonable until the oil warms up. No need to start it and let it run for a minute or longer. Drive moderately until warm.

Augenbrauezug · 03-02-2011, 09:47 AM

I start it 5-10 minutes before I plan on leaving. I just like it to have a few revolutions before I start driving. Makes everything feel 'better' to me. I certainly don't wait for the oil temp to get into normal operating temp if that's what your getting at.

I start the car and let the RPMs settle, then drive. Don't go full throttle or anything and you will be fine. Newer cars are designed to be driven in the cold.

What he said ^

I wait until the faster RPMS decrease to idle to let oil and fluids move around some. No WOT or other silliness until temps get to reasonable numbers.

I usually turn my N55 on, let the RPM drop, then wait an extra minute. Once I begin driving, I take it easy on the engine while I wait for the Oil to warm up.

Pretty much what everyone else said.

6th gear at 30 mph for the first 5 miles?

ChristosK · 03-02-2011, 05:08 PM

I try not to push it hard and keep lower than 3000rpm until i see the oil temp climbing.
On the other hand after a hard drive I to let it cool down for 2-3 min .

"Do not wait for the engine to warm up while the vehicle remains stationary. Start driving right away, but at moderate engine speeds."

I do the exact same thing. No need to sit in your car and let it run or start it and leave it running unless you want to waste gas and kill your mileage.

^ This.

Anything else is just wasting gas that would be better used to actually turn the wheels.

If you think your car is too cold, you should've gotten the seat heaters. That thing gets hot fast.

TN_3 · 03-03-2011, 02:01 PM

I remember reading somewhere that allowing your car to idle for an extended period of time when you first start it is bad for the engine. This is due to the fact that at idle, the oil is not being brought to operating temperature fast enough, thus actually causing more wear and tear on the engine. The cold oil is not very viscous, so the engine works harder to cycle it. You want to get that oil warmed up in the shortest amount of time, but without high RPMs that can obviously cause harm. The best advice is to start the car, allow to idle for about a minute, then drive the car, being mindful of the RPMs, until the engine reaches operating temps.

mtechnik3 · 03-03-2011, 02:32 PM

Well said TN 3 ^^

I let the N55 RPMs settle to a normal idle (which take around a minute). I drive at moderate speeds and do not push the car hard until the oil temp gauge moves off the first mark (which is about 10 minutes or so in normal ambient temps). After that I'm not really worried. These new engines are pretty incredible and well engineered.

I never let the engine just sit and idle for extended periods of time - unless it's winter and I'm defrosting and cleaning snow off. Or I'm in stop-and-go traffic.

I do not believe a cool down is needed any more either. Most turbo cars used to need an idle cool off to circulate the oil/water in the turbo to cool it down before shutting it off. Most modern turbo cars' cooling system is designed to circulate convectively when the pump stops. It couldn't hurt though.

Indeed it is. When cold, the fuel mixture is very rich, and has a tendency to dilute the oil and wash it off the cylinder walls, causing premature wear.

Start the car and drive off immediately using only moderate power to warm it up as quickly as possible,

Wouldn't the cold oil be more viscous? Think about warming up honey or maple syrup in the microwave - viscosity and temperature are inversely proportional.

Don't believe the supersition stuff posted by others in this thread. Start the car and drive off. That's about it.

Ha, yeah. My bad...I think I was going to type "...is not very fluid..." but then decided to throw viscous in there, and forgot to delete "not".
