Been away from the forum for a long time, so I'm not up to speed with the goings on here. Are people around here still into the the LCD product line like they used to be (i.e. FP Plus, LC20)? I've been approaching the end of my supply, and trying to determine if it's worth replenishing. My Mazda6 has been given both of these products for the majority of it's life thus far. 110k on the odo right now. Knock on wood, the car still runs very nicely, and I've never even had a check engine light. Granted I do take excellent care of it. The only difference is that my average fuel mileage has slowly tapered off from its peak of 28mpg down to 24mpg. It peaked around 60,000 miles. I attribute the decline in performance to the age of my vehicle. Otherwise it runs very smoothly, and seemingly still has all of its power. What I like to believe is that these products have helped keep my engine healthy. Although sometimes I wonder, but that's the natural born skeptic in me. So now that my car has accumulated some age, I'm wondering if I have reached the point of diminishing returns with the LCD products. I'm not even sure how I can determine the usefulness of the products anymore other than by tabulating fuel consumption. What I really want is to maintain the condition of my engine as best as possible, and get at least 200,000 miles out of the engine.
