How to report original website name from end of post title

Hello: I notice one of the rss import would often leave their brand name at the end of the post title, for example, the title might be like "Toyota teamed with Exxon to develop lower-carbon gasoline - Autoblog". I'm sure this is just how the data is provided via RSS. Is there a way to program the RSS to feed settings to remove " - Autoblog" each time it does the post title import?
