Boxster's this much of a gas eater?

Have you actually calculated the MPG? What is it?

The thing that just bugs me is just c'ing how fast the needle on the gas gauge goes down baby driving the car.Maybe new spark plugs will help what other peeps have said plus the bad cats. i may have if thats where the rattle,tin hitting metal sound coming from rear end when cars warms up to normal temp. Thanks for rely's again.

Does anyone know the estimated MPG for the 00-02' 3.2L engine? How much did it differ when from 02'-04'?

Mine's an '02 S. Details a few posts down (roughly 320 miles per tank, which is 23+mpg) in mixed driving with plenty of wide open throttle. Also, DJ1 also posted results of 22-24mpg for an '01S in this thread as well.

How many gallons of fuel does a 986 hold? A 987 holds just over 16 gallons.

Well my last tank, I got 361 miles till my gas light came on. Then I filled up my car when the gas light came on and my reciept said 13.9 gallons. So I'm estimating 26MPG with 1/2 city 1/2 fwy. And I don't drive slow. Hehe...

Again, I would forget about the needle until you actually calculate the MPG you are getting.

Did I miss the number or have you posted this yet?
