As a side note, the manual recommends oil changes only every 15k miles, which is nuts.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I've seen advice given in this forum about waiting until your rpm's are at a certain value before driving the vehicle after starting it, and then not driving it over 3K rpm until it's at operating temperature. Just curious what's behind this advice, as it's not the guidance given in the Porsche owner's manual. Per the manual:
"Do not let the engine idle to warm up. When starting the engine, be ready to drive immediately."
"Drive vehicle at moderate speeds and avoid engine speeds above 4,200 rpm during the first 5 minutes."
Was the info in the manual superseded by real-world experience at some point to become the de-facto guidance for these vehicles?
Thanks!
Mike
After starting, simply drive away straight away.
Warming up works best while driving.
EDIT : When the engine/oil is cold I keep the revs between 2000 and 3000 rpm. Too high is not good, too low also not.
Take a look at Rennvision YuTube Channel. A lot of the info that is circulating is a byproduct of identifying what may contribute to bore scoring. So preventative measures have been introduced which are independent of the Porsche manual. As a side note, the manual recommends oil changes only every 15k miles, which is nuts. So as time passes, problems occur, we learn and adjustments are made.
**Sarcasm** Yes, by all means, after starting the engine rev it to 7000 RPM and nail it on the way out of the driveway before the water and oil temperature reach operating temperature. What could go wrong? And, by the way, do this with all of your cars in Ohio. Why wait for them to get to operating temperature? Indeed, no car needs to warm up...especially in cold tempatures. Oh, and change your oil at 15000 miles interval per the manual. Why waste money? Your engine will love you for that.
I see the sarcasm, but I think the question is not about revving a cold engine to 7000rpm.
The question is, I think, if you should start the car and then let it idle untill the revs drop before driving off.
I think this is a bad idea and that you should start the car and drive away immediately.
While driving with the cold engine/oil, treat it nicely of course so keep the revs low (but not too low!) until it is hot.
I think 5 minutes is not enough.
Yeah, I get the sarcasm
My point was that the manufacturer puts guidance and recommendations into the owner's manual, but sometimes we know in the real world those don't hold up well. I'm new to these parts, so was just curious what the general consensus was among folks who've been around for awhile. Thanks.
Mike
Start car, wait about 15 seconds, start driving.
Avoid brisk acceleration.
Keep rev's below 3K until COOLANT is at temp.
Then, you can drive a tad more briskly, keeping under 4,200 rpm until the OIL WARMS UP completely!
How do you know when the oil warms up?
When you know the oil is good and hot, note where the oil pressure needle is at idle. Now you know when the oil is warmed up.
NOW YOU CAN HAUL A**!!!!
Have fun and enjoy your 996!
Its like drinking from a fire hose. You want to do as little harm as possible to it while finding ways to enhance engine durability. You get on RL and it scares the crap out of you until you realize you own a 20+ year old classic Porsche 911 and it is no different than any other 20+ year old classic. There will be issues and more importantly, there are solutions to every issue.
Best advice is to read the threads on Bore Scoring, IMS, Oil Pressure Instability, and Oil Starvation. Don't jump to any conclusions but take in the info, go down the rabbit trails of references to YuTube channels, websites, companies and various solutions. Yep, it will take a little time but if you plan on owning your 996 for awhile, it's worth it.
You will find a common sense approach to maintaining, servicing and enhancing your car that addresses issues and provides solutions. If your not mechanically inclined, get yourself a great Porsche Indy. Plenty of them out there.
IMHO, the 996 is the best damn 911 ever made, or I would have sold mine a long time ago over the last 19 years. It bridges the gap between the air cooled and techno wizard later model 911's beautifully. I have driven everything from the 964 to the 991 on the track, and the 996 is the most fun and rewarding out of the bunch. Sure, the 991 is a he'll of a lot faster and a he'll of a lot easier to drive fast, because the power and technology makes up for the shortcomings of the driver, but the 996 is more engaging and fun to drive. Get your engine rebuilt and add 100 HP and you will be passing 991's like they are in a 912.
The chassis is that good.
Like others have said, watch the Rennvision series Focus On: Bore Scoring.
Why you shouldn�t let your 996 idle at start up and keeping the revs down until the oil is up to temperature is explained.
If 4,200 is the manufacturers's target and 3,000 is my mental target then that works fine by me. I try to be careful but I honestly do not look at the tachometer too much - I listen to the engine. So I'm certain I hit 3,500, maybe even 4,000 sometimes before she's all the way warmed up. 1,200 RPM is a fine margin for error in my opinion.
