Started using Schaeffer products after George Bryce recommended it. He owns Star Racing and uses this product along with engine oil. He showed a break down of a race engine he built that had very minimal wear and tear. I used it in my built 107 and loved it. Now I use it in my 2020 RGS. Tired of the clunking noise. Change all your fluids to Schaeffer and you won’t regret it.
