Like every new Porsche owner I am reading through the Owner's Manual. Under section "Starting and Stopping Engine" pg 182, it reads do not warm up engine when stationary, Drive off Immediately!

If the outdoor temp is < 30's F, I have a been starting and allowing about 5 minutes of warm up.

Opinions, what is your translation of what is stated in the owners manual and am I doing damage here!?

Thanks

 

I don't know that you're doing damage but you probably are wasting gas. I don't warm mine up. But then again it's not that cold here either. I don't think any modern car really needs to be warmed up other than for occupant comfort.

 

In all my cars I just wait for the car to idle down and then drive off.

 

Get in. Crank. Turn on seat and wheel warmers. Seat belt. Drive off.

Thats my routine even with the -3 windchill I'm expecting this morning.

 

Me too. I just get heavy on the gas, obviously, until it warms up a bit.

 

That's a good point. Especially if it's a turbo you want to let it get warmed up before spooling them up too much. I wait until the water AND oil both hit the normal range before getting on it.

 

I would never hop in a car and just go when its cold out. I let mine warm up for at least 3-5 mins to let the oil circulate and get things up to temp. When its extremely cold out I also keep my rev's below 2.5k-3k RPM's to prevent "cold seizure". Guys who hop in their cars and rev them to the moon are looking at big repair bills (engine rebuilds). As a guy who as been working on cars as a hobby for over a decade I think warming up a car has a huge impact on its longevity!

 

Nobody is talking about reving a cold engine "to the moon" (at least I'm assuming mto made a typo).

Porsche specifically states that you should start and drive off without idling to warm up. They also stipulate that the revs need to be kept low until it is up to operating temp (i forget the exact range they say, but I keep my diesel below 2500 as beat I can and mostly below 2000).

Having the motor under a moderate load will warm it up and get the fluids circulating faster than just letting it idle.

The exception of course is those areas where you really need a block heater, but there starting without first warming the block pre-heated is asking for trouble. Once it is pre-heated though, its still start and drive off.

 

It going to come down to personal preference. I live in the mountains and to get out of my building I have to go up before I can start going down. If I don't warm her up I have no choice but to rev past 2500 so I warm her up. My wife is one of those jump in and go types and she broke a valve spring about 5 months ago.
