Yes. Currently it's in beta but it's working. Connect your phone/tablet with Google Drive or Dropbox and check - autobackup and sync option. At start Fuelio will check the data and it's newer data it will import this data.
But the other people have their own google drive.
How do I do it without giving them my login info?
Create new Google Drive account or for Dropbox I'm using App API which is not giving access to your data - only the Fuelio directory.
Right now there is no way to sync between different accounts - for this we need third party server and store your data somewhere.
it seems to be working to share the content of the sync folder in Dropbox (/Apps/fuelio/sync) with the other account after creating the folder /Apps/fuelio.
i haven't try the auto sync, but manual sync works
Is there an update according this feature, I know a few people that would like to use this
Previously I shared my vehicle on two different phones, but now I cannot share between me and my wife
