Do I need to add the Syntek Engine Boost 2.0 on an empty tank?
A. Syntek Engine Boost 2.0 is made to disperse quickly into your complete fuel tank; it does not matter if you add the additive on an empty tank or a full tank. However, it makes more sense to add the additive before you begin pumping your fuel. Q. When I pour the additive into my tank, there seems to be some that sits on the metal flap of my gas tank inlet, what happens to that product. A. The additive will only remain on the top of the inlet flap for a few seconds before seeping beyond the flap and down into the fuel tank. It is recommended that you add Syntek Engine Boost 2.0 before you begin to pump the fuel which helps disperse the additive throughout the fuel tank.
