Question

Does anyone know how i can find out my gas milage on my van?

its a 99 Pontiac Montana Van?

Answer 1

Its pretty simple really fill your tank lets say 20 gal. for example reset your trip odd. or just record the exact milage on the odomiter at the time of fill up, then drive normaly when the tank is empty take the total miles driven since you filled up and divide by 20 asumeing you put 20 gal in thats your mpg. another way is check your owners manuel it will tell you the capacity of your tank in that case just fill it completely and use same method example tank capasity 18 gallons you drive 450 miles on this fuel  450 divided by 18 = 25 miles per gallon, also note city driving and highway driving your mpg will change you will get more mpg on the highway then in the city because your engine will consume more fuel in the city do to stop and go driving, hope this helps good luck
