Title: Works for me
Review: First, I drive moderately and maintain my vehicles in good condition, so I get good fuel economy with or without additives. We have been using Lucas Fuel Treatment for several years in several vehicles, and it consistently gives approximately 5-10% increase in fuel mileage. My driving routine is painfully consistent and I calculate the numbers carefully, so I know that it is helping. Since performance is very subjective -- things like air temperature, humidity, fuel freshness and fuel batch blend can all affect engine performance -- I will not attest to any performance gains. But for fuel economy, this stuff just works for me. It's also nice to know the fuel system and upper cylinders are getting lubrication when using the harsh oxygenated winter blend fuels here in CA.
