I have the Lucas in the trans of my 92 t-bird and and works great. The car shifts much better then it did! I have used the fuel injector cleaner in other cars with great results.

Chris,
I, too, have used various gasoline additives in my many vehicles over the years, on a semi-regular basis. No more. Page 249 of the 2007 Fusion Owner's Manual under the heading "Fuel quality" clearly states: "Do not add aftermarket fuel additive products to your fuel tank. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use high quality fuel of the recommended octane rating. These products have not been approved for your engine and could cause damage to the fuel system. Repairs to correct the effects of using an aftermarket product in your fuel may not be covered by your warranty."
Sounds pretty clear to me, as is the 87 octane rating advice.
