It's been awhile, but a few morning trips I've had incorrect readings over 100mpg. How it happened is the Insight would stop at an intersection, but autostop would not stop the engine. I'd cut the engine, but for some reason the display would read 150mpg. I'd arrive at work with over 100mpg for the trip.

Anyone have a situation like this?

61.5mpg lifetime - 82mpg in recent months

Hi DeltaFlyer,

The only time my Insight behaves like what you described is after a normal refueling - not topped off.
The FCD will become very easy to peg out, same speed I normally drive and get 80-100 mpg now becomes 125-140 mpg.

It doesn't last though, usually after 5-8 miles the readings return to normal.

If I do a FAS, I do notice the fuel gauge reading changes, normally reads lower after restarting.

Regards,

Yup! Happens fairly often when I have done a forced autostop (FAS) and restart the ICE - not sure exactly what causes it, but I think if I start to apply power too quickly after restart, the computer gets confused and stays at 150mpg regardless of the ICE demand. I usually catch it within a couple of minutes and do a FAS again to reset.
