[Verse 1]
Her engine's running and her fuel is clean
She only uses it cause she's a machine
She don't need it though, just to get around

[Chorus]
Keep filling that fuel line, keep filling that old fuel line

[Verse 2]
The awesome power of electricity
Stored for you in a giant battery
She runs so quiet, she's just like a ghost

[Chorus]
Keep filling that fuel line, keep filling that old fuel line
Keep filling that fuel line, keep filling that old fuel line

[Post-Chorus]
Fill her up
Fill her up
Fill her up
Fill her up

[Verse 3]
The world is ready for a whole new game
Some old-timers just want to stay the same
But they still advertise how clean and green they are
[Chorus]
Keep filling that fuel line, keep filling that old fuel line

[Verse 4]
But she don't listen to what they saai
She burns domestic green fuel instead
She don't use much though and that's smart for a car

[Chorus]
Keep filling that fuel line, keep filling that old fuel line
Keep filling that fuel line, keep filling that old fuel line

[Post-Chorus]
Fill her up
Fill her up
Fill her up
Fill her up

[Verse 5]
She's not the car that she used to be
She wants to take you and she wants to take me
Into the future, that's her destiny

[Outro]
Keep filling that fuel line (Hey), keep filling that old fuel line (Fill 'er up)
Keep filling that fuel line (Hey), keep filling that old fuel line
Keep filling that fuel line (Hey), keep filling that old fuel line (Fill 'er up)
Keep filling that fuel line (Hey)
