Hi Cheryl, how long have you had the car? Has the consumption recently and suddenly changed? City traffic can easily be the worst for fuel consumption and tends to increase the carbon deposits on valves, pistons & plugs. Best to do a lengthy drive say 50 miles plus on open roads to blow the cobwebs out as it is often called. 200 to a tank doesn't sound terrible if say you are driving in London and only short stop/start.
 
Hi guys

Hope somebody could spread some light on this matter.

I have a Porsche Cayman 2.7 and and im concerned that my mpg is low? I am currently getting 200 miles to a full tank on city driving. This is purely city driving as i dont really take it on the motorway, does this not seem too low?
Anyone else got a cayman 2.7 that could maybe spread some light on what they are getting on a full tank etc??

If it has dropped from the mpg that you are used to, may be worth checking the tyre pressures as low pressures can have an impact on fuel consumption.
 
Have you started using the Air Conditioning more? Or driving with the windows down? This can also increase fuel consumption.
 
Hi Cheryl. That does seem remarkably low. I have a 3.4 S and live on the outskirts of London yet seem to be getting at least 300 miles and mostly around 350 miles from a tank of super unleaded. Is there a smell of fuel around the car after it's been parked up for a while? There could be a leak?

or waving your arms out of the window?[:D] seriously,cheryl-i am afraid in purely city driving thats all i ever got from cayman s-on purely motorway 70-80 mph i would get 320 miles per tank and mixed driving a tank would do around 260-270 just not that economical cars i am afraid.... but SUCH FUN[:)]
 
What do you see on your computer readout? MPG? Range when full? Do you fill the tank fully or just put in so many pounds worth? Porsche State Urban as 20 mpg so a full tank should give you 280 miles range but increased road works and other delays can easily exceed this. I usually get around 340 miles/tank on mixed driving but normally fill up just after the warning light comes on at which point I can get about 12 gallons ( 54.55 ltrs ) in the tank to brim it.
 
I think it depends on type of driving - my 2.7 Cayman gets up to 37mpg on the open road when driven gently (400+ miles to a tank) but suspect a lot less in town. It's quite a big engine and is not really operating efficiently on short town journeys. Do your engine a favour and go for a long drive in the country at the weekends!
