Bruce Tetford uses Lucas Fuel Treatment for Mazda 626

Dear Don,

I am writing this letter to inform you of the great results I received from my first use of your products. I was in the past skeptical about additive products but have changed my mind since using LUCAS Oil Products.

The LUCAS Upper Engine Treatment & Fuel Injector had fabulous results my first use. I drive a Mazda 626 and was averaging around 420 to 440 Kilometers per tank of gas. The first time using the above-mentioned products I attained 478 Kilometers on a tank of gas ...

I was extremely happy with the results and have since added the engine treatment and transmission treatment to my car and will continue to use the upper engine treatment also. I will be adding all 3 products to my wife's Ford Explorer and will keep you updated as to the results in both vehicles.

Yours truly,

Bruce Tetford
