So I’ve been watching the fuel economy gauge for a couple days and something seems “off”. It seems like the gauge is over estimating how much fuel is being used at idle. I first noticed when I spend a few days remote starting (and running for about 10 min). During those few days of doing that, my fuel economy went down to like 10mpg.
so the other day I ran a test. I reset the gauge and drove around town for about 10 miles. When I shut the truck off, my fuel economy read 13.8mpg.
The next day, I got in the truck and started it (I did not use remote start). As soon as the truck fired up, the fuel economy gauge was at 8.5mpg?
how did I loose 5+ MPG overnight when the truck did nothing but sit idle in the parking lot?
