Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Leading evidence: 'Reset several times' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Reset several times' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Run engine very hard will raise combustion temps enough

Occasionally running an engine very hard will raise combustion temps enough to burn off carbon deposits.
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.

Same amount I'm driving over the same roads every day. I usually average around 21 miles per gallon. Autocross my car on saturday, now my miles per gallon has jumped up to 23.5! Any clue as to why?
Maybe there is some truth to the fact that tracked P cars and those that get driven hard perform better than garage queens that just serve as dinner for mice
Haha! I was going to say that. It's also possible that your not revving out your shifts. I'm sure keeping your RPMs way below the limiter would save gas.
The "Italian tuneup" is a real thing. Occasionally running an engine very hard will raise combustion temps enough to burn off carbon deposits. Given that you had some carbon deposits built up (that's the only real possibility I can think of), you might want to add a bottle of Techron or Seafoam gas additive and drive it in a spirited fashion to finish the job.
Gas mileage? Who cares? If I looked at it I would only be concerned if it were too high, meaning I'm not driving my beauty with sufficient spirit........hard to get gas mileage when the petal is always close to the floor......to me the stat I like to look at is average speed over time...
This is a an interesting possibility, but my quick google of summer versus winter blend suggests that summer blend actually gives better gas mileage. I've never looked into winter/summer blend differences before seeing your post, so happy to be corrected if I'm wrong.
I filled up on the way into he lab this morning. $5.89 a gallon for 92 octane at Texaco. I get 19mpg. The saving grace, its a dual edged sword, is I live on an island that is 44 miles long by 30 miles wide with 112 miles of coastline.
Could be race track syndrome. Once you drive fast on a track the thrill is gone for driving fast on the street...cause it ain't really that FAST.
There is no point.
Not to mention highly dangerous for your fellow drivers. And secondly, hazardous to your license.
I've not driven my car to {my} limit on public roads for many many years. I'm grateful that my car only has 300 or so HP. It's fun and sounds amazing and I can use it, in short bursts, without breaking all the rules. I can't imagine needing more. Heck my favorite car was a 50hp Fiat spider. Well, until the 911.
My first and only track experience was disappointing as I was seriously held back by my instructor. Now if I were to return to the track it would seriously lower my normal average driving speed. I view NJ highways as basically my never ending HPDE circuit.
I have to second the upper NJ roads especially near the northern boarders near Penn. beautiful slow sharp turns and twists near the VanSant airport lots of fun at 6/10ths safe speeds
Nah, frustrating was when I had my 2017 C7 Grand Sport. My days of blasting down the highway like a maniac are over. A quick spurt here and there to keep the blood pumping is all I need nowadays.
I have noticed that my average gas mileage has dropped significantly since moving to Louisiana. I went from about 25-26 MPG average in WA to struggling to get over 22 MPG here. If it isn't somehow the the weather or the difference in gas. I am pretty sure it is the increased traffic/speed variation. I feel like for whatever reason the 996 is hyper sensitive to that compared to some of my past cars. So maybe you experienced a little less traffic or kept a more consistent speed on the highway?
Edit: those numbers are per gauge and have been reset several times to remeasure. I do not keep an actual log.
