Hi Paul,

My Scion XB has a average speed between resets feature.  I
intentionally did not reset since purchase last August.  Today it
turned over 10K miles and I thought you would be interested in the
result:  22 mph.

What an intense duty cycle. :)

To be fair, it is only a daily driver and rarely sees a long trip over
60 miles.

That is so cool. Modern technology is so awesome, too bad classiccars just look so much better. Vlad

Hi Chris,I bought an '09 Mazda 3 and picked it up April 9. It showed 9.9L/100Km for
fuel consumption. It now has 25,000Km or about 15,500 miles and is down to
7.6L/100Km. Fuel receipts are about 6.5L/100Km (+/- 26 MPG US). My average
speed is 72KPH or about 44mph. This has not been reset since new either.I also found out this engine is not the direct injection. That is on the
2.0L one. The injection on that one is during the intake and does not start
until after the exhaust valve closes. The injection pressure is about the
same as other multiport engines as the compression cycle has not started.

And the point is?

Just another illustration of the disparity between aircraft engine duty cycle and that

of the automobile.
