Crossword Clues

60 across Pepsi
_ _ _ _ COLA

When I saw this clue, I was thinking, "What is another way to say Pepsi?" So, I thought SODA. Since I'm playing on-line this is what I got -

SODA That means it's not the right word but 2 of the letters are correct. Take out the wrong letters and you get -
_O_A COLA

I'm half way there. What's another word that means Pepsi that would fit?
