Default Gas milage computer!

I haven't reset my average mpg meter in more than 6 or 8 tank fulls. It has been reading 20.6- 20.8 the whole time. About 800 miles of this is freeway miles so it takes a long time to change even 0.1 mpg. This morning on the way to work in less than 2 miles the mpg jumped to 24.6! Has anyone had a similar experience? I reset it to see what happens next.

On the highway, mine reads 32.00 or higher depending on the actual road.
I have gone over 500 miles on one tank.

I think he is talking about the jump in MPG, what happened is the mileage counter used by the computer only goes to 999.9 miles, so when it starts back over at 0's it started recalculating like you had just reset it. Atleast, that is what I was told when mine did the same thing.

Thanks for the input. That could be it.

Those things can be pretty unreliable. Need to start doing your own calculations at the pump to see how accurate it is.

30.2 MPG average for the trip to Carlise and home. 960 miles on little over two tanks. That's the top of the third tank.

Averaged 34.1 for the first 380 miles.

I've manually caculated the MPG against the computer and it's usually within +- .1
