I put 15 dollars worth of gas in my car at Shell Gas Station at 1396 E 41 and Knight St., Vancouver, BC, and I drove to 1723 Cliffe Avenue, the PetroCanada Gas Station in Courtenay, BC. Can anyone tell me if that is good gas mileage.

 

Welcome to DF
The best way to check your mileage is to fill the tank and write down your mileage. Then drive until you fill up again, then divide gallons of fuel to mileage. So if you put in 10 gallons of fuel and you drove 200 miles, you will avg 20 miles per gallon.
