Antonio Mazzola uses Lucas Synthetic Oil Stabilizer in Mazda RX7 Race Car

A month before the race season started, I put a new motor is my race car. A wankel rotary is the power plant. At my first race, an oil seal was leaking and lead to tremendous oil loss and embarassing smoke from my exhaust. The safety team at the track warned me that the smoke was causing loss of vision for the other drivers. If I could not fix the problem I would have to park the car for the weekend. I added what I think was almost a gallon of Lucas and the smoke was gone. The car ran cooler and faster than ever before. I was able to take 2 seconds off a lap! Thank you Lucas for creating this wonderful product; I never fill my oil without it.
