I have been using FX1 for about 8-10 years. I find FX1 enhances the lubrication system of the engine more effectively than just using engine oil. I use FX1 in our family car and camper with equal effect. After initially adding FX1 the tick- over speed increases, indicating the positive effect by reducing friction of the internal engine bearing surfaces. This, in my opinion, enhances the life of the engine.
