Common Questions (GL-4, 75W-80 vs 75W-90)

Is Petro-Canada TRAXON Synthetic MTF 75W-80 GL-4 or GL-5?
This oil meets API GL-4. It is designed for synchronized manual and automated manual transmissions. It is not a GL-5 differential oil unless the vehicle manufacturer explicitly allows GL-5.

What is the difference between 75W-80 and 75W-90 transmission oil?
75W-80 is thinner at operating temperature and optimized for fuel efficiency and smooth shifting in modern gearboxes.
75W-90 is thicker and typically specified for older or higher-viscosity transmission designs.

Can 75W-80 replace 75W-90?
Only if approved by the vehicle manufacturer. Using a higher-viscosity oil than specified may cause hard shifting, increased drag, and higher fuel consumption.

Why do modern commercial vehicles specify 75W-80 instead of 75W-90?
Modern transmissions are engineered to reduce internal friction, improve fuel economy, and maintain smooth shift quality, especially during cold starts. 75W-80 supports these requirements and enables extended drain intervals.

Is 75W-80 suitable for heavy-duty commercial use?
Yes, when OEM-approved. High-quality synthetic 75W-80 fluids offer strong shear stability, wear protection, and thermal resistance suitable for commercial operating conditions.

What happens if GL-5 oil is used in a gearbox designed for GL-4?
GL-5 oils contain higher EP additive levels that may reduce synchronizer performance, potentially causing poor shift quality and accelerated synchronizer wear unless explicitly permitted by the manufacturer.

Important Note

Always follow the vehicle manufacturer’s specification for viscosity grade and API classification. Using the correct GL-4 75W-80 oil is critical for proper synchronizer function and long-term transmission durability.
