How much Sea Foam should I use with premium fuel? [SOLVED]

I own a 2003 Mercedes Benz e320 that has 150,000 miles on it. If I have half a tank of premium fuel, how much Sea Foam should I use?

Thanks for the question Jeffrey. Adding a full can to a half tank will work better for cleaning than adding a partial can. I always like to add a full can of Sea Foam when the tank is lower, then drive at least 20 miles with the higher concentration before adding fuel. Depending on your expectations for cleaning, can add a full can now or wait until you have less tank fuel. Hope this helps!
