LOWERS OPERATING TEMPERATURE
BLUE DIAMOND SEVERE DUTY GEAR OIL improves thermal stability and friction reduction, protecting against varnish and sludge deposits

REDUCES WEAR
BLUE DIAMOND SEVERE DUTY GEAR OIL is infused with our patented FR3 Nano Technology which helps increase boundary layer protection and improves film strength for extra protection

REDUCES SHEARING
BLUE DIAMOND SEVERE DUTY GEAR OIL reduces shearing under severe duty applications, allowing the oil to remain in specifications for peak performance

IMPROVES OXIDATION STABILITY
BLUE DIAMOND SEVERE DUTY GEAR OIL was formulated specifically for severe duty applications, helping reduce breakdown, lowering oil consumption and extending gear oil change intervals

BLUE DIAMOND SEVERE DUTY GEAR OIL was formulated for severe duty applications. The gear oil additive formulas are based on 100% poly-alpha-olefin (PAO) Group IV and high-quality Group V synthetic oils. The infusion of our patented FR3 Nano Technology and high zinc additive package extends the performance and anti-wear protection to levels unmatched by any other gear oil on the market. BLUE DIAMOND heavy duty gear oil also provides increased oxidation and thermal stability, deposit and sludge prevention, reduced oil breakdown, high wear resistance and longer drain intervals. BLUE DIAMOND heavy duty gear oil is recommended as a gear oil for any demanding severe duty application, such as towing, hauling, challenging terrain driving, commercial use, utility vehicles, heavy equipment, tractors, motor homes, and other severe duty vehicles.

At Hot Shot’s Secret®, we infuse our oils with FR3 Friction Reducer® due to its exceptional performance-enhancing properties. FR3 Friction Reducer® is specifically designed to reduce friction and minimize wear within an engine’s moving parts. Oils with this advanced friction-reducing technology provide superior lubrication, creating a protective barrier between metal surfaces and reducing metal-to-metal contact. This results in reduced friction, lower operating temperatures, and improved fuel efficiency. The infusion of FR3® also helps prevent premature engine failure by minimizing wear and tear on vital components, such as pistons, bearings, and camshafts.

By incorporating FR3® into our oils, we offer a superior product that extends the lifespan of engines and other oil-lubricated components, minimizes maintenance requirements and ensures peak performance and reliability. Hot Shot’s Secret® oils maintain their performance for longer periods, extending oil change intervals and reducing overall maintenance costs.

      If you are running our gear oil no need for FR3 as the gear oil has FR3 in it already.

  2. Question

    Casey

    I have a ‘99 Dodge 2500 Cummins, currently running the Black Diamond engine oil and I’m very impressed! The truck is 550rwhp, with a Dana 70 with 35’s. Would the Blue Diamond 85w-140 work well? I don’t currently tow, it’s mostly for street/offroad use.

  4. Question

    Gerry Rose

    Hello, We have a 2018 RAM 2500, 6.7 stock not deleted with limit slip rear diff. 55K miles tow a 35 foot fifth wheel about 25 % of the time. I’m changing the rear diff oil. Question, RAM recommends SAE 75W-85 what would you recommend and why? Actually switching to all your oils/fluids, how about engine oil, transmission fluid, transfer case oil and coolant recommendations? Thanks much, Happy New Year!

      Our 80w110 S11 gear oil would be ideal for your truck; for the engine run our Blue Diamond series 15w40 oil, and our atf+4 for the transmission assuming it is an automatic. Thanks!
