You make too many assumptions. This type of thinking is what contributes to the myth that garage queens are doomed to an early death. My 997 is a garage queen an it is not a daily driver. I drive it only on good weather days and I always warm it up appropriately ( drive away with light throttle and and less than 3K rpms until the oil reaches an indicated 200F). I always drive Porsche at least 45 minutes but generally 1.5 hours at a time. It exists in my garage purely for my driving pleasure. I drive my DD to places like the post office because other drivers are often careless.
Actually, I break my cars in and warm all of my cars up the same way and I never had an oil consumption issue with any of them.. even the 911.

I should add that some folks feel that all you need to do is bring the oil temp up to 212F ( boiling point of water at sea level) to remove all of the water from the crankcase. This is not the case. Actually if these engines only got up to an oil temp of 160F and were run for and hour, they would have less water in the crankcase than an engine that has reaches 212F and has been shut down after another 5 minutes. It takes time. When you bring a pot of water to a boil on the stove you still have a pot full of water. The pot will eventually dry out whether at 212F or 160F.

I assume you are driving a 997.1. The 9A1 motor is significantly different than previous motors when it comes to shifting at lower rpms. Holding the motor below 3K is pretty easy, especially with a PDK that is actually programmed to favor low rpm shifting (unless you put your foot down).

I don't have any trouble keeping my. 1 cars between 2,000 and 3,000 rpm during the warm up cycle until the oil is at 180 F. The car will run 74mph in 6th gear below 3,000 rpm, so even if you have to go let on a highway before it's fully warmed up you can still achieve this.

Long time lurker here, bought a 997.2 a year ago. This forum has been so helpful - thank you to the participants in the community. I've been a little tuned out here and just recently read the thread start to finish and watched videos in short time. I too want to commend Jake, Charles, and Baz for all they are doing to bring concern to the forefront. I will be following along to find out about proper ways to treat our cars. Good tips so far with more to come it seems. My car is consuming more oil than i'm used to but this is my first Porsche. Just ordered a UOA.
Bronz I feel for you but in ways I'm envious that your car is disassembled at Flat6.
Selfishly glad I wasn't on pins and needles following this saga over the winter - would've crushed my mood and hampered ski season. Reading all the way thru in spare time over 2 days was a roller coaster.

First.. Anyone want to buy an unopened case of DT40 ? LOL
Secondly - Pete do you go to the trouble to pull your oil sample before the Techron? Going with the assumption that if it affects the oil it affects oil analysis.
Lastly - is it overkill to change to DI40 and also use Cera Tec ? (This is for a Turbo S)

but even with new MT fluid, Cup car cables and a factory short shifter kit, I find it more comfortable and natural to shift at between 3.5k and 4K during the warmup cycle.

I've learned a lot in this thread - thanks to all - especially, Jake, Charles, Baz and Pete.

I let Blackstone know about the Techron in the first few oil samples I submitted and they said it doesn't show up since it burns away and
I didn't need to mention it.
How much for the case of DT40?

I’ve been away from this thread awhile. I have a 9A1 motor but WITHOUT DFI. So the DFI is the aggravating factor. No DFI, theoretically no problem correct..

Burning Brakes
The only documented cases of bore scoring have been the result of cold seizure. The leading causes of cold seizure appear to be block fatigue or poor warm up practices.
