I'm assuming you've changed to Autumn air in your tires. Otherwise you might as well sell the car now before word gets out.

33 is one of my favorite roads. 58 is great too. Last time I was on the 58 it was fresh surface with a bit of grease still seeping out. Every turn was a slide. My daughter lives just a couple miles off of the 58. The east west roads in California are often overlooked. They shouldn't be!!!

I was north of the Golden Gate. Up to Ft Bragg and east on the 20.

Ft Bragg is/was where Red's Headers (Red Hamilton) had his flathead Ford business. Yes I have flatheads ( refer to previous crazy definitions pages). CA 58 west from CA33 has been paved in recent past but now is all settled in an perfect. The switchbacks where you can reach out and touch yourself going the other direction are a blast. CA 33 starts here in Ventura so it is just down the street for me. As to the technical topic, ( this is a tech forum (?)) I sprung the extra money to upgrade to the free full four season air at my last air change. This is very important. However since the latitude here is 34.2 something degrees, I am not subject to the 35 degree North latitude rule (air must be changed at Porsche dealer at least twice a year with real German air) . This is because the square root of the latitude times the second differential of the forcing function of the alternator belt acceleration is well within factory limits. Obviously this affects the air in the tires. Those north of 35 degrees may have problems.
Cheers!

I guess that means I need to sell my home and move further south. Can't be bothered having to import special German air.

You are lucky living so close to the 33 and that National Forest. And I couldn't agree more regarding the 58!!!

I've had my 997.2 for 18 moths now and I kept a log from the start. To date I've got a rolling average of 1.5 quarts to 3600 miles.

Sorry 997.1 only. Apologies

During my 60k service on my 2009 C2S at my independent Porsche mechanic, I informed him of the my oil usage 1quart per 2k miles and he said that is normal. Since he was changing the spark plugs as one of the service items, I asked him to scope for bore scoring - after he did, he said there were no signs of scoring and everything looked normal. He said some of 997.2 engines burn more oil than others and it's within Porsche spec. Car drives great so I just did it for peace of mind.

Not sure it would help at this point in this thread, but rather than say an engine burns no oil, because all engines burn oil. Maybe have the first couple choices be 1 bar or 2 bars etc. I burn 1 bar every 5000 miles so it is nothing, but it also isn’t close to 1 quart.

No oil burned in 4-5k miles between changes

Could we add a choice,

"I have no idea because it doesn't have a dip stick and the electronic one is a pita"

E368

I'm with you on hating the fact that we don't have a dipstick but how exactly is the electronic one a pita? Having both would be nice, and if I had to chose one, I'd choose the dipstick so that I could actually see the color of the oil. However, the electronic system is pretty easy to use, in my opinion.

The only complaint I have about the 997.2 system is you have to get to temp to read, unlike the 997.1.

Other than that I have no issues with it, it works well

2011 C2S, 43k miles. Oil change each year after about 3k miles. No noticeable oil consumption.

Busta Rib

89K miles, 7K-mile intervals, Motul 8100 X-clean 5W40. No burning. Smugness not included.

2010 C4S with 83K miles.

I guess I am the odd man out here. I follow the Porsche maintenance schedule (these guys have posted a fairly accurate schedule on their site) for my car which is every 10K miles or 1 year. As far as burning volume goes, I am at 1 line below the top according to the oil change animation on my cluster. I drive the car daily and put ~12K on her yearly. I just drove it from NC to St. Augustine and back this week and not a drop is missing according to the indicator.

Folks, dare I say RTFM without making enemies? Page 208 of my manual states "It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant. If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1,000 km) or more. It then goes on to indicate "The difference between the minimum and maximum marks on the segment display is approx. 1.3 quarts (1.25 liters). Each segment of the display corresponds to approx. 0.42 quart (0.4 liter)".

Yeah, I'm one of those geeks that reads the manual cover to cover when I buy a new car or bike. It's amazing what I learn doing that.

FWIW I recall reading that the auto oil check process was developed to ensure accurate pressure for the operation of the variocam. I can't find the original source of that so consider that statement anecdotal at the moment.
