I picked up my 2014 991.1 C4S from the dealer's service center today. They did an oil change in addition to some warranty items (A/C, trim related, not related to engine).
My drive back is about 27 miles, and what I noticed was oil doesn't come up to temperature as quickly as it did in the past. For at least a good 5-7 miles, it was way below 120, and maybe at about 10 miles into the trip or so it came up to 170, and stayed there. (2-2.5k rpm highway cruising) Normally this car fairly quickly warms up to about 190-200 oil temp. What was somewhat more weird was every now and then it was slowly moving up to 180 ish area, and when I lift off from gas, it'd drop back down to 170-165. I don't remember a lift off reaction in oil temp before.
Anyways, after a while, I lost patience and stepped on it do a few low to high rpm highway pulls, which brought the temp at about 190-195, and it seemed to have stabilized there, even after I slowed down. Normally, spirited driving is above 200.
So wondering if this sounds familiar to anybody, maybe w the oil change now the oil volume is a touch higher, and it takes longer to warm up, or runs cooler? Another risk would be the dealer using the wrong oil, which would really suck -- will check w them what they used.
Separately, it seems like they've put on 22 miles on the car, from Thurs to today. Sounded a bit excessive to me for a test drive. Do you think that's reasonable?
Doesn't sound right to me, I've never had something like that happen after a change. Does the oil measurement feature indicate an overfill?
Oil measurement feature says "oil level OK". It's about two ticks higher than when I left it (so I guess I had one fifths before, which was OK, now it's three fifths, which is I guess more ideal, still OK).

Hmm I wonder if I just haven't seen that because I don't let mine get down to one fifth?

So before the oil change, you were 4 bars below full? FYI- that's about 1.6 liters down. Not surprised it's runner cooler now.

I think he was 3 below because the top fifth is over the optimal level. Still, I think people forget it's a flat 6 and you really need to check and (if needed) top off the oil regularly, it burns a little oil by design.
Ok good to hear. I guess more and new oil running cooler does make sense.
Yeah so out of the 5 bars (the line between 4 and 5 being tagged as "max" and the line below 1 being tagged as "min") I was at 1 bar full, after oil change we're at 3 bars full.
I might've been a bit late on this oil change admittedly (maybe ~7.5k miles or so since last one). Agreed the oil should've been topped off.
Sent an email to the SA about the 22 miles, see what he says. Somewhat unrelated (but maybe not) when they had this car for sale, it was listed online at 8700 miles or so, and when i test drove it, it was at 9600 miles, so I asked them w t f was up, and I think back then they said something like their sales manager drove it during that time or whatever. They're not really the cream of the NJ Porsche dealers - I'd been using them mainly due to convenience (they're storing tires for me for free and I literally have zero space) but yeah maybe not the best judgment on my part.
So it wasn't the cheese steaks, even though it's always worth a quick run for a cheese steak -- they had to drive it around to figure out the A/C issue, which does make some sense I guess since the A/C wasn't blowing any hot air regardless of temperature chosen - they might've tried to drive the car around to see if it starts working after warming up or something, or attempt a fix and see if it worked? Will have to let it slide.
Never really dropped the car off there for anything other than putting the winters a while back so they really wouldntve had a chance to top up oil - but that much i should be able to monitor/do myself in all fairness --- right after brand new oil change, i'm at a tick below A

Changeover valves are your liked culprit. They should know that. Search here for more info.
