How Does Diamond Nano Additives Help Reduce Wear, Heat, and Increase Power? 

Adding diamond-hard carbon nanoparticles to engine oil creates significant improvements in engine performance through three key mechanisms, as demonstrated by BestLine Racing and academic research

1. Surface Polishing & Friction Reduction
The nanoparticles (5-10nm size) act like microscopic ball bearings between moving parts. They:

• Fill microscopic grooves in cylinder walls and bearing surfaces
• Polish metal surfaces to mirror-like smoothness through mechanical action
• Reduce friction by up to 60% compared to conventional oils

2. Protective Film Formation

• Particles embed themselves into metal surfaces under pressure
• Create a diamond-reinforced boundary layer that:
  • Prevents direct metal-to-metal contact
  • Increases surface hardness by 15-20%
  • Withstands extreme pressures (up to 300,000 PSI)

3. Thermal Management

• High thermal conductivity (3300 W/mK) carries heat away from critical areas
• Maintains oil viscosity better at high temperatures
• Reduces operating temperatures by 20-30°F in engine tests

Real-World Results
BestLine's testing shows engines using this additive demonstrate:

• 3-7% fuel efficiency improvement
• 50% reduction in component wear
• Extended oil change intervals (up to 2x conventional)5
• Improved performance in both gasoline and diesel engines

The Swiss Federal Institute study confirmed these nanoparticles create a "rolling/sliding" dual-action effect - rolling like bearings under low stress, then forming protective surface films under high pressure. This combination makes them particularly effective in high-stress areas like piston ring/cylinder interfaces and crankshaft bearings.
