Jim Fahlin uses 75- 90 diffy fluid and bearing grease in 1970 Nova and my trucks

Hi, my sister is starting to race at a local race track. We use the 75- 90 diffy fluid you guys produce and the bearing grease. Since I use your product on the 1970 Nova and my trucks, I already know it will out perform other competitors products for racing. Plus I am a BIG fan of NHRA Racing.
