One thing I've always wondered is why the directions on so many fuel system cleaners will say to run the tank empty first, BEFORE adding the additive to the tank. Does it really matter how much gas was in the tank before adding the additive? I'm guessing they want to fully mix the additive in the tank, but even if your tank was above half full, it's still going to mix in there properly. I bet that even if the tank was nearly full, and you only needed to add 2 or 3 gallons, that it would still mix properly.
As long as you run the tank WITH the additive in it right to the end, for maximum cleaning time, to me that seems like the more important step, not how much gas was in the tank at the time of adding the product.
Thoughts?
