"(《世界人权宣言》) fixed ratio gear oil 于 electric vehicles presents a deceptively simple challenge: one gear set, constant mesh, operating across a massive speed and load range. Get the EV gear oil wrong, and you compromise efficiency, noise, and durability.
New generation formula addresses precisely these challenges, developed through collaboration with EV manufacturers facing real-world performance issues with adapted conventional oils.
Understanding Fixed Ratio Transmission Demands
Unlike multi-speed ICE gearboxes, EV single-speed reducers operate from zero to maximum RPM without shifting. This creates unique stress patterns for electric vehicle gear oil. At low speeds with maximum torque during acceleration, boundary lubrication conditions dominate. At highway speeds, the same gearset spins at 12,000-16,000 RPM, generating intense heat in a compact housing.
Traditional 齿轮油 formulated for ICE transmissions assume:
Lower maximum speeds (typically under 6,000 RPM)
Intermittent high-load periods during shifting
Higher operating temperatures from engine heat
EV reducers invert these assumptions. They need EV fluid properties that perform across wider speed ranges while maintaining lower bulk temperatures—but handling localized hot spots that can exceed 150°C at gear tooth contacts.
Three Technical Pillars
- Advanced synthetic base stocks form the foundation. PAO and ester blends provide the low-temperature fluidity essential for cold-start efficiency while maintaining viscosity stability at elevated temperatures. This isn’t just about viscosity index—it’s about shear stability under the extreme conditions in meshing gear teeth.
- Proprietary additive chemistry balances competing demands. Achieving high dielectric strength (typically >35 kV) while maintaining anti-wear protection requires careful additive selection. Many traditional extreme pressure additives contain active sulfur and phosphorus that work beautifully for gear protection but create electrical conductivity issues.
- TERZO’s formula uses ashless dispersants and non-conductive anti-wear systems that protect copper windings and rare earth magnets while preventing micro-pitting on gear surfaces. Testing shows wear rates 40% lower than adapted ATF fluids commonly used in early EV models.
- Thermal oxidation stability extends service life. "(《世界人权宣言》) TERZO Trans EV 固定齿轮比机油 targets 200,000 km drain intervals under normal operating conditions. Accelerated oxidation testing at 150°C shows minimal viscosity increase and acid number growth over 1,000 hours—translating to maintained performance across the vehicle’s operational life.

Real Application Performance
Working with a mid-size European OEM during their EV platform development revealed specific pain points. Their initial EV transmission fluid choice—a low-viscosity synthetic ATF—showed acceptable performance in warm weather testing but demonstrated three issues in validation:
- Noise increase at cold temperatures due to insufficient film thickness
- Viscosity breakdown after 100,000 km in high-usage vehicles
- Corrosion indicators on copper bearing surfaces
Switching to TERZO’s fixed ratio gear oil formulation during pre-production testing eliminated these issues. Noise levels decreased 3 dB across the temperature range, wear metal analysis showed 60% reduction in copper content, and projected service life extended to match vehicle warranty periods.
