Suggestion
If anyone ever catches me checking the mileage on the 996, someone just come and take it away from me.
Leading evidence: 'Check mileage' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check mileage' (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.

Suggestion
Mine improved from combined hwy/city 18 to 21, just by filling the tires to the proper pressure (rears were at 36psi before...).

Suggestion
27.3 mpg @ 80 mph average from Austin to Dallas - combined city and highway use I usually see about 18 mpg
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.

what the difference between the C4s and C2 what are you guys getting vs. EPA. I am planning a long trip and has hoping to figure gas cost. Thanks
(I have a C4S)
Thanks
Onboard computer says 28.8mpg but my own calculations at the pump consistently shows 24mpg.
I do mostly highway, 70miles a day, if I drive the C4S.
(Other days it's the F150 = 16.5mpg)
C4S: I average 18 mpg with a rural commute -- along a twisty, hilly road beside a very big lake... I never complain about commuting
On a long road trip across several states I got 22 to 23 mpg at a reasonable pace.
Have a great trip.
Ah, but do you have the C4/C4S with the microscopic fuel tank?
On a road trip, I have to fill up more frequently than I have to pee. My 944 could go for another 150 miles before a fill up.
Mine improved from combined hwy/city 18 to 21, just by filling the tires to the proper pressure (rears were at 36psi before...).
Check your pressures folks....
Get these numbers.....can a supercharger help on gas?
On the pedal, no way! With my foot in it, it gets about 10-11. But here is the kicker. With my TPC charger, If I stay out of it and get up on the highway for a trip, I cruise at about 75-78 and get about 29-30 to the gallon if I really watch the pedal and stay out of the rpm's. I can only assume that the added efficiency has something to do with the SC and although it makes no sense for me, it has been great this summer for a number of roads trips. The info was not off the trip comp or the GPS, it is a straight division of mileage vs. gas purchased and then calculated. MPG still sucks in the city with the SC though. I tend to no bitch and moan about gas prices because we are only now getting close to the rest of the world.
A good friend of mine was bitching about gas prices last weekend and I merely expressed my opinion that it was hard to hear him complain with a $7 cup of coffee in his hand. As a matter of principal, I have never walked into a Starbucks and don't plan on it. Maybe all those Starbucks closing can be turned into gas stations.
On a serious note... on long pure highway trips doing between 70 and 80mph I have gotten between 28 and 30 mpg on several trips. It is possible.
Normal hwy trips with me having a little fun on occasion is more like an average of 26mpg
Like everyone else, around town is in the mid to high teens.
You know every supercharger manufacturer always says you'll get better fuel economy out of the SC, and I never understood it (because i assumed parasitic loss > efficiency from nominal boost), so its good to hear from somebody who can validate (even with a strosek kit and those steamrollers you have on yours!)
+10000000 on the starbucks
Not like me. I probably averaged 16-17 in LA, since I've sent the car back to NY I'm averaging 13.3 per computer all day long. Incidentally that's what I average in everything I own (pretty close). Last long road trip I did about 24mpg on the highway. But I'm carrying around a lead foot.
I'll answer the same way I always do on these threads...
If anyone ever catches me checking the mileage on the 996, someone just come and take it away from me. I could literally be getting 8 mpg and I wouldn't even know it.
