Blue Diamond +4/D3/M5 is recommended by Hot Shot’s Secret for the most common ATF specifications, including but not limited to ATF+4, DEXRON III and MERCON V. It is formulated to protect against fluid breakdown that is common with severe-duty applications, such as heavy towing and challenging terrain and will help clutches, bearings and bushings last longer and perform better, the company says.

Severe Duty Blue Diamond +4/D3/M5 is developed from combined 100% poly-a-olefin (PAO) Group IV and high-quality Group V synthetic oils. For added protection, the transmission fluid formulas are infused with Hot Shot’s Secret FR3 nano carbon lubricant technology. FR3 improves shearing and oxidation stability, film strength, removes varnish and sludge deposits and reduces friction and heat. The nano technology lubricates and fills in the microscopic irregularities on machined surfaces to extend the life of the transmission while under heavy load, challenging terrain or the stress of high horsepower or torque, the company says.
