Synthetic 75W-90 Gear Lube delivers unbeatable protection and fuel economy. Series 2000 Gear Lube allows working surfaces to glide past one another with minimal friction, keeping heat, wear and fuel consumption at their lowest.
Viscosity makes a real difference in fluid performance.
Less friction means better fuel economy, less heat build-up and less wear. In commercial vehicles, improvements in fuel economy are a top priority and Series 2000 has established its superiority. In passenger and race vehicles, superior friction reduction offers a major heat dissipation and protection advantage. That's especially important for race vehicle differentials. They run so hot, they are often unsafe to service during a race.
