Fuel Consumption Calculator

Fuel Consumption Calculator

Help yourself "Go Green" by using this handy, easy to use fuel consumption / cost calculator to know your vehicle fuel economy in miles per gallon (mpg), litres per kilometre (lpk) or litres per 100 km.

What's the benefit of cutting back on automobile fuel? It's better for the environment. Better fuel economy means less pollution emitted by cars and less dependence on foreign sources of oil. Save weeks worth of fuel each year!

What is this Fuel Calculator?

Fuel Consumption Calculator is a free tool that calculates your fuel economy in multiple formats e.g. miles per gallon (mpg), litres per 100 km, etc. so if you are needing an Metric Fuel Consumption Calculator or an Imperial Fuel Consumption Calculator this tool does both.

An Easy Mileage Calculator

Enter your distance traveled in miles or km's and the volume of fuel used in litres, US gallons, or Imperial gallons. When entering the fuel costs, the Fuel Consumption Calculator will provide the fuel cost per mile or kilometre (km) and your average monthly / yearly fuel cost.

Required information

Distance Traveled:     Mile    Kilometre (km)   

Volume of Fuel:     US gallon    Imperial gallon    Litre   

Optional information

Fuel Cost:    (e.g. 20.50 = $20.50)   

Daily Average Distance:     Mile    Kilometre (km)   

Tips for Driving more Efficiently

Drive Sensibly - Aggressive driving (speeding, rapid acceleration and braking) wastes gas. Road rage with quick starts and hard stops can increase fuel consumption by 30% or more!

Observe the Speed Limit - While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at higher speeds. Reducing your speed from 70 mph to 60 mph or 120 km/h to 100 km/h can reduce fuel consumption from 10 to 20%.

Remove Excess Weight - Avoid keeping unnecessary items in your vehicle, especially heavy ones.

Avoid Excessive Idling - Idling gets 0 miles per gallon and generates greenhouse gases. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

Use Cruise Control - Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

Tire Pressure - Check the tire pressure regularly. Too low pressure will decrease your fuel mileage.

Follow the Recommended Maintenance - A vehicle that is well maintained means it will operate with greater efficiency.

Combine Your Errands - A little planning can make a big difference in fuel economy. When your engine is cold, it uses more fuel than when it is warm. Combining errands can improve your gas mileage because your engine will be warm for more of the trip.

Other items to consider - Check your air conditioning level, use energy conserving oil, replacing spark plugs, coolant level, fuel treatments and cleaners.
