Fuel Economy

996C4S 3.6ltr 28.5mpg average over all situations including driving in France,Belgium and Germany - unrestricted[;)]
 
I usually get 32ish on a long run, and mid to late 20's on local runs. Never lower than 26. I tend to use Esso super unleaded. I believe you can use regular unleaded as the car has knock sensor though power will be down slightly.
 
Hello Dave,

I have a 996 C2 Cabiolet 3.4 2001, and with spirited driving and an advanced driving course, got through a tank full in a day, the car is returning 29.8mpg, I know this as I have kept all my petrol receipts, sad I know, but this is an accurate average usage for one year.
I know that if I drove my car to work, I would get 40mpg on the way in, and 12mpg on the way home, it's the lead foot syndrome.

Regards
Dodgy
 
Hmmm maybe my turbo was just unusually frugal before?! I used to get 32-35mpg reliably (every long journey I did) even got 37.2 driving for 1h 20 into london from Northants in traffic.

I usually sit with the cruise control on at around 75 (gauge) and change at 3k rpms when warming the engine up on the 15min drive to the dual carrigeway.

Now mapped I cant get it over 30mpg driving the exact same way. It averages 26 mpg if under 1hr on motorway, 28-29mpg if a long drive 1h 30+ I assumed this was because the turbos were spinning from below 3000rpm on light throttle where before you had to really poke the throttle to wake the turbos sub 3k.

P.s. I always use v-power and if I arrive with flushed cheeks, a silly grin and orange glowing exhausts. The guage typically reads about 14mpg.
 
I can cruise at just over 90 and the boost gauge reads 0.0, so I expect that is your 'problem'. I can about 29mpg on the gauge if I cruise at 70, but life is too short for that. Mine's a Tip, so probably 2mpg worse than a manual.
 
I tend to reset the trip computer after every fill up and work out the millage that way. Its normally the same for each fill up, however just when i reset and pull out the petrol station im doing about 7 to the gallon lol. I think the computer is pretty acurate anyway so you could just use that.
 
I am as sad as Dave Green, I keep a spread sheet as well with the same information!!!!!!
 
From my experience 996's are pretty decent on fuel.

My daily hack is a 2.5 V6, this gets around 28 changing at 2k all the time and doing the A road stretch at 65-70mph.

The 996 can do 80 in sixth and return high 20's.

Around town it's also comparible to most other mid sized engine saloons.

Your 2mpg difference is very small on a run, it's going to be down to the road surface on the oposite side and inclines even though you may not notice - I can get 4 mpg more on the way home than on the way to work doing exactly the same speed driving in exactly the same way in both cars.

I think that these cars get quite good milage really, my last car was a 1.4 corsa and it only got 38 to the gallon, i think that when you have a big engine it doesnt struggle so much at high speeds like smaller cars do (if you watched that episode of top gear with the prius you'll know what i mean).

Chris you mean the Prius vs the M3? When the M3 did better MPG round the track. I enjoyed that, i hate the prius!

Yea thats the one. Stupid electric cars[:D]. IIRC when im doing the national speed limit[;)] in the 996 its only doing 3000 revs or so(i could be a coupleof hundred out on that tho).
