You'd think that the song was about ecstasy but it isn't. It's about the economy and how Debbie couldn't afford paying for gas so she had to sell her car. Now she walks everywhere. Quite obvious when you read the lyrics.

I see the lines about the selling of the car, but what does the title phrase (I'm On E) mean then?

I'm on E = I'm on empty Like a gas tank.
