Fuel Savings
Burn less fuel, get more power
More complete combustion means more energy from every gallon. Vehicles fitted with HYMIX™ systems showed the following in field measurements:
- 10–30%average fuel economy improvement
- 10–30%average engine output improvement
- 90%+smoke reduction
- Less DEFreduced urea (DEF) consumption observed
