Low gas mileage C2S
I’ve been getting 14mpg city/highway mix and mostly in Normal driving mode the last couple of months.
When I got my car (used 2020 C2S with 3k miles in December ‘20) I was getting around 16+… only thing that’s changed is using the AC a lot more because of the ~100F heat in Texas, and recently installed Sprint P08 performance air filters.
Anyone else getting lower mpg?

Is your 992 a PDK or manual? Gas mileage with the manual transmission tends to run much lower than the PDK which upshifts a lot more than I do.
My 2S manual mileage can be great on the highway ( 30+ is usual at 75 mph) but terrible on short blasts (10-15 is not uncommon) .

It’s PDK
My total tank (I don’t have extended tank option) goes up to around 200ish miles before empty, so my numbers are just coming from miles driven / gallons filled, not from the car info itself which I don’t know why i didn’t bother checking on there lol, but yea it still sucks to be this low.
It’s at the dealer now for PCM/gps issues so I’ve told them to look at this as well.

992 C4S with PDK
The highest that I have seen is 28MPG (indicating 480 mile range on the dash).
More typically, I see 24MPG on the highway and 18MPG (or less) when I am blasting on the backroads, driving like an a$$hole. It's quite good on gas.

This is all urban miles since last fill-up...lots of blasts to redline from on-ramps into traffic, and generally running the car with "verve." Always, ALWAYS in manual mode and using a lot of revs, a mix of normal and Sport+ (never use Sport mode due to ridiculous farting). I don't consider this kind of gas mileage in the city unusual or problematic as it's in the range of 8 mpg to 14 mpg I've seen the last decade or so on another 911, a Cayman S, M3 and AMG. It gets a bunch better on the highway in the 992 - into the high 20s MPG - even though I rarely use 8th gear (it drones a bit in 8th under 140 km/hr). Over a longer timeframe, the MPG would look better as my wife uses the car as well, but she's always in Sport+ and driving pretty briskly...probably closer to 12 mpg, I'd guess
Yes, this is U.S. mpg. Uh-huh, uses a lot of gas. No, not a problem at all... I'm certain the car is operating within design parameters <g>

I generally see 18mpg in my C2S MT, but had to make a round-trip down to southern NJ yesterday evening and saw 30 mpg for the first time…similar to my daughter’s Kia!! Don’t know how they do it but I love that this car has multiple personalities…
