Fuelly User (Non-Gas Cubby User)
 

I intially bought Gas Cubby and signed up for Fuelly at the same time, but ended up using Fuelly over Gas Cubby because of Fuelly's website, vehicle stats, and design. As a result, I have a Gas Cubby account, but there is no information in it.

Being a Fuelly user, what should I do with regards to the combining of the two services?

At this time, you don't need to anything as far as prepping for the integration. When we release GasCubby 3.0, you'll probably want to at least play around with the app to familiarize yourself with it.
After we have sync set up, then you'll be able to see your Fuelly data on-the-go, whenever, wherever.

That sounds awesome. Can't wait for the release! Thanks, Robert!

Im in the opposite boat. I purchased Gass Cubby and then signed up for fuelly. I have all of my data in Gas Cubby how do i get it into fuelly ?

Same situation as the OP then.
My response remains the same as well except in your case, you might as well familiarize yourself with Fuelly.
