im having a problem with getting the correct gas mileage on my expedition like when i go to put gas in it will say i have 200 miles to empty but after driving a few miles it will drop to 180 for some reason.... other times when i take it for a drive i look at my miles to empty and compare it to miles driven they do not match for example i had 200 miles to empty but after 10 miles it says it took like 17 miles off to empty so im not getting the correct driven miles to miles to empty dont match up so what is causing this problem i have changed the oil and filter added marvel mystery oil put seafoam into gas tank and even used throttle bottle spray so im not sure what else i can do to fix this problem
