My 1987 Mazda Pickup was making some lifter noise. It is a fairly common problem, and since these lifters only had about 50,000 on them, I didn't want to replace them right away. I tried the Lucas Heavy Duty Oil Stabilizer and all ticking has ceased, and I have more power and a smoother running engine. My beloved Mazda has 460,000 on it and runs beautifully. We now use this product, along with the Lucas 15/40 truck oil, in all our vehicles, from the Mazda to the Peterbilt to the farm tractors. Wonderful products!
