What will happen if you put 2 bottles of fuel injection cleaner in your gas tank instead of 1?

It states that you put 1 bottle of fuel injection cleaner in your gas tank. What will happen if I go ahead and put 2 bottles of it in my car? I'm trying to improve my gas mileage significantly and clean my fuel tank significantly as well. What will happen?

1. It will foul out the spark plugs, after the tank of gas is replaced, do yourself a favor and save some gas by replacing the spark plugs. God Bless
2. Id only put 1 in at a time.Do as stated on the tin!.
3. burn the rings off the pistons. Melt the top of the piston Cause cylinder damage
4. done this before here in ny in thw winter.doesnt really help that much. better idae to check?change fuel filter,spark plugs and wires, air filter, pcv valveetc. this will improve your mileage. BTW improperly inflated tires will reduce your mileage as will using ac or driving with the windows down.
5. depending on the volume of your fuel tank.............. say 60 liters average >go from 60:1 ratio to 30:1 ratio fuel to solvent obviously you've doubled the dulution ratio, is it really going to make a difference? probably not. But scientists have tested the product at the lab, and confirmed that this is how much product we need to clean affectively and at the same time not rob performance or harm the engine. instead of throwing 2 bottles in save that 2nd bottle for your next fill up.
6. Just follow the directions on the bottle, if 1 is good 2 is NOT better.
