I've always waited at least 30 seconds or wait until the RPM drop below 1000 RPM before I drive off in all my cars(Mercedes). Do I still do this with Porsche? The manual stated no excessive idling. Any suggestion will be appreciated.

FWIW I let mine idle high and wait to drive off until it drops down....about 30-45 secs. Don't know if it's needed but that's what I do. I figure it gives the CATS a chance to heat up etc.....

 

Not neccesary, I start it and start driving (slowly) for the first few minutes.

Other then that drive it like you stole it!

 

I wait till the idle drops down, then take off. However, I keep it below 3k until the water and oil heat up before I let her have it.

Just about every vehicle ive owned, ill sit in the garage for about 30-45sec...then take off slowly till the cars warm. My supra ill sit in the garage for a minute or two, let the exhaust get a little heat going before I drive it & again take off slowly, ill shift at about 2500-3000rpm till it gets nice & toasty.

 

Same here, start her up, back her out and you're off!
By the time you make it thru your residential area, it's more than enough of a warm up.
I just really can't see engines being made in the 21st century that require so much babying. Maybe if it's for aviation but not on the road.

 

I believe the reason the manual states no excessive idling is to discourage the consumer from burning unnecessary gas. It's Porsche's contribution to the energy conservation.

As for me, I agree with everyone else. I'll wait about 30-45 seconds to allow the idle to come down. If it's really cold outside it will take longer and I usually just drive off slow. Before I open her up, I wait for the oil temp to come up. It just gives me that extra security that the engine is well protected and lubricated. Although in theory this is not necessary if you're using 0-50 wt oil since the ambient temp should not make the oil more viscous. Another reason is that the internals slightly expand as it warms up, and I don't want to be stressing the engine during this "small" change.

 

Must be a Canadian thing!

 

Yeah, those older engines that were made out of metal and used oil for lubrication...must have been a pain in the @ss.

Exactly...I wait for the motors rpm to drop to proper idle. If I am in a hurry I let the car coast a bit at the higher idle which propels you.

i drive under 4k till it warms up a lil and then i beat the living crap out of it... 2000 miles of abuse and havent lost a drop of oil... :-D

 

i start it up, and keep it 3k and under till it heats up. with a turbo car if everything isnt expanded properly you'll get blowby. which is bad.

 

I start it , give it a few seconds and slowly warm it up . The Porsche warms up fairly quickly though . My Honda Si is a bit faster to get warm and the M3 takes longer than both .

No hard driving until the car is totally warmed up .

 

30 secs won't hurt it as far as idling. The more important procedure is to drive gently until everything is warmed up. I let the oil temp reach 200 before spirited driving. It's not that hard to achieve, since it's so damn hot here in Arizona.

 

my car takes 2 min until the RPM drops down to idle ?????
