Fuelly is where nerdiness and MPG collide. They provide a great, free service that allows users to track fuel efficiency on multiple vehicles with a dead simple web app.

Using the service is as simple as recording the miles on your odometer & the amount of fuel pumped whenever you fill up your vehicle.  Fuelly does all of the math and presents the data in an easy to read format. Since you can view your MPG over time you can tell when it may be time to change the oil, inflate the tires, etc. to get your MPG back up.

Now, you’re probably thinking that’s great, but not really very nerdy.  The nerdy part is that you can add notes that correspond to your odometer readings. So, if you are really obsessed(i.e. nerdy) with getting the most MPG’s out of your vehicle, you can add a note when you made a change to your vehicle and see how it has affected the efficiency.

For example:

As you can see removing the 32 Ska Band stickers from my 1985 Chrysler New Yorker increased my fuel efficiency by .1 MPG, while replacing my fuzzy dice/ w carbon fiber dice had no effect on efficiency.

Of course scooters already get incredible gas mileage, but there is always room for improvement. Scooter fuel efficiency also tends to be more easily affected by maintenance & engine issues so the savings from using Fuelly could be significant and make you more aware of upcoming maintenance issues. They’ve added Owl to their list of scooter brands and most everyone here at Owl HQ is now using the service.
