Fuel Saving Tips
I've had a vehicle with a particular brand and style of tires that resulted in 10% overestimation of miles driven from fill up to fill up. Currently, I've got a pickup that under accounts for miles consistently versus GPSs 1.8%, while my other two vehicles over account by 2.2 and .5 percent, respectively. I just check maybe once per year and when I buy new tires, so that I publish as accurately as possible, my mpg.
