I drove in between 75-90mph and got 23mpg on my 370mile single trip to San Jose and on the return trip I got 22mpg. It only took me 5 hrs, so go figure.

my speedo once read 160 while the digital speedo reads 158mph.

All cars speedos over-read. I had my C32 at an indicated 265km/h, while it is supposed to cut at 250.

all of them do show over at higher speeds.. im not sure if this will work on our cars, but with bmws at higher speeds if you reset the avg speed while driving it will show the accurate speed.

thanks guys....

i suspected the speedo was off. the big surprise was the fuel consumption. maybe the motor is loosening up. just turned 18K clicks.

off topic but took it for b service on sat, got a c320 loaner. not bad, has some scoot. make me think the new 4valve engine with 6 speed might be quite nice.

Anyone know how the cpu determines the MPG? Because when I was flooring it one day, my MPG increased from 20 to 22, but this doesn't make sense. At full throttle, my MPG should go to crapola. My guess is that it isn't very accurate and doesn't take into account the amount of fuel coming into the engine (full-throttle at 90mph or half throttle at 90mph, makes no difference)?

I think they just calculate the distance you've gone divided by the remaining fuel in your tank.... so it depends how your car levels...... if it's not (just like when you floored it - all the fuel should've shifted to the back of the tank and I think the censor is also at the back), the censor would show inaccurate fuel level, hence, inaccurate MPG.

...MPG measurement

couple yrs back I had a VW corrado g60 with a pretty nifty computer. if you reset it coming down a gradient you would momentarily get 100 mpg until you got back onto the gas......

unlike the northeast recently, toronto was devoid of cops. i'd say be prudent, pick your moment, take your chance.

In many models there are 2 fuel sensors not one.
