I haven't really fleshed out the vehicle class stuff yet. The EPA has its own system I am going to need to mesh with since I am planning on having vehicle specs autoload from the EPA/personally generate REALLY FREAKING BIG database that I am working on currently.
Anyway, it should read gasoline but at the time the add garage function was borked and I put it in wrong,
Also, I just fixed the album rating feature, so now you can leave ratings on people's albums, which will eventually be used to create a "Best of GCA" type page and also used in search etc.
