Fuel consumption numbers for your vehicle are something you could look up on a site like Natural Resources Canada or www.fueleconomy.gov. Those are the official Canadian and U.S. government sites for fuel efficiency ratings. But why use the government's numbers when it's much more satisfying -- and accurate -- to measure this yourself?
Earlier I suggested that when you drive, you should record your mileage and fuel purchases: this helps you to plan more and drive less. Today we refine your record-keeping and add to it.

Why do you want to know how much fuel you use?
Once you know your vehicle's fuel consumption, you can really commit to lowering it. The numbers make it real: measuring, recording and crunching the numbers makes them yours, so it's personal! Also, once you know fuel consumption you can convert it into fuel economy measures like mpg (miles per gallon) and mpg-imp (miles per imperial gallon). That helps you compare your vehicle to others in cases where they don't use L/100 km. Plus it gives you another way of looking at how you use fuel. It puts your fuel use down on paper and motivates you to cut it back.
How do you do it?
First of all, keep recording your daily mileage and fuel purchases with that pen and paper (or booklet) you keep in the glove compartment. It's an on-going record of fuel use that lets you figure out your long-term average fuel use (such as a full year), zoom in on a specific time frame (like your summer vacation) or serve as data back-up if you mess up the cool technique I'm about to describe. The cool technique takes discipline and tight control over your vehicle's instrument cluster. And you have to keep your receipts. Are you ready for that?

- Always fill the tank.
- Record how many litres you bought, total mileage and trip mileage. Either on the receipt or in the booklet.
- Reset the trip counter after you get the mileages, and before you leave the gas station. Every time.
So that's the cool approach to measuring fuel consumption, and we're done for now. Next blog I'll explain how to use the numbers you wrote down. You'll be a fuel consumption Jedi!
