Gas mileage acting up ??

[Elizamtz17]

So I have a 2015 Mazda 6 today I noticed that the gas mileage(the one that tells you how many miles you have left) in numbers are going up and down. My oil is up to date and I dont know what can be causing this? Any ideas ?

... you’re serious? It changed based on how you drive. You’re not always using the same amount of fuel when you drive. Stopping and then accelerating uses more fuel
