Why do you get better gas mileage on a full tank to half?
So, if your tank happens to have a tank that is shaped as I described above, there is a greater volume of fuel in the top than the bottom, so it will use it up slower than the smaller quantity of fuel at the bottom, so the level (Gauge) will fall slower in the top than the bottom.
How to calculate gas mileage per 100 kilometers?
When you calculate liters per 100 kilometers (l/100km) you are calculating volume per 100 units of distance, or fuel consumption rate. Fill up your tank with fuel before you start a long trip or the block of time you want to track. Record the trip starting odometer reading at the time you fill up. At the end of your trip, fill up your tank again.
What causes a car to have bad gas mileage?
Using more fuel than necessary lowers your mileage and is bad for your engine. If your vehicle doesn’t have a carburetor, a blocked air filter can cause bad acceleration, but not bad mileage.

When to worry about your car’s gas mileage?
When the system is working as designed, and under certain conditions, maximum fuel efficiency will be achieved. Numerous factors can have an affect on fuel efficiency so it is usually a constantly changing number but a serious and sudden drop in miles per gallon is cause for concern and the vehicle should be inspected.
Which is the correct formula for gas mileage?
Equivalent fuel economy/efficiency ratings are converted and shown for all units, mpg US, mpg Imp, km/l and l/100km. mpg = miles per gallon. mpg US = miles per United States gallon. mpg Imp = miles per Imperial gallon. km/l = kilometers per liter. l/100km = liters per 100 kilometers.
What causes a sudden drop in gas mileage?
Such a drastic drop in mileage is often associated with a bad 02 sensor. I’ve had them go bad and cause a 25-35% drop in fuel efficiency. Did you have anything done to the car just before the mileage dropped? A drop like this has to have an assignable cause, and it often traces back to a maintenance that was just performed.
