# How Cerma STM-3 Technology Works
> The Science Behind Self-Cleaning Engines

## What is STM-3?
STM-3 = Self-cleaning Treated Metal, 3rd Generation

## Silicon Carbide (SiC) - The Key Ingredient
- Mohs hardness: 9-9.5 (diamond is 10)
- Thermal stability up to 2,700°C (4,892°F)
- Chemically inert and non-toxic

## How STM-3 Works
1. Add Cerma to engine oil
2. Nano SiC particles circulate with oil
3. Particles embed into microscopic metal surface imperfections
4. Creates ultra-smooth ceramic-like surface
5. Self-cleaning action prevents carbon and deposits

## Measured Benefits
- Friction reduction up to 90%
- Fuel economy improvement 4-21%
- Emissions reduction up to 92% (CARB compliant)
- Temperature reduction 10-30°F
