Hi all:

Yesterday while driving to work I switched over to trip a on my dash, trip a was reset to zero when I started driving my HCH and is my lifetime mile per gallon (LMPG) reading, it was close to 10,000 mile, with 73.4 mpg on it . Today I looked back at it and found that the mileage part of it had reset to zero, but the mpg number had remain the same, 73.4. It seems to me that the trip meter, a or b, will only read up to 9,999 miles before it resets to zero. Has anyone experience this same problem? And is this an accurate way of tracking LMPG?
