I have the habit of reseting my trip computer and checking the mileage to empty everytime that i fill up the car.
Now the question is, how come everytime i fill up it marks 400-420 miles to empty but then im only doing an average of 280 miles everytime before my reserve light comes on?

 

haha. i know what u mean. i have gotten as high as 495 but in reality only lasted a good 320 miles. that thing is way off imho.

 

But it makes you feel good for that half a second before reality sets in.

 

i agree with bobbyspeed...i does make you feel good filling up and the cluster stating you have 495 miles to empty then you floor it to get on a highway and your down to 320

haha

 

so the damn thingy fooled me and here I have been driving like a grandmother to see if anything improves?

oh well part of the Porsche experience, I still love my CS!
Thanks all!

 

the default setting of the trip computer is for ***** driver.

 

... and idling.
