Specifically, GL-4 oils are formulated to avoid the harmful effects of certain additives found in API GL-5 gear oils, which can react negatively with the yellow metals (brass) commonly used in synchronizers. Using a GL-5 fluid may cause premature wear and damage to synchronizer components. Therefore, adhering to the API GL-4 specification ensures the use of a lubricant that provides effective lubrication and protection without causing detrimental interactions with the transmission’s internal parts. Always verify the specific API GL-4 recommendation in your vehicle’s owner’s manual.
Viscosity Grades⁚ 75W-85 and 75W-90
The viscosity grade of a manual transmission fluid (MTF) indicates its resistance to flow at different temperatures. 75W-85 and 75W-90 are common viscosity grades recommended for Nissan manual transmissions. The “W” denotes “winter,” signifying the fluid’s performance in cold temperatures. The numbers represent the viscosity at high and low temperatures. A 75W-85 fluid will be thinner at low temperatures than a 75W-90 fluid, allowing for easier cold starting and improved low-temperature lubrication. Conversely, the 75W-90 fluid will provide slightly thicker lubrication at high temperatures, offering better protection under heavy loads or high operating temperatures. The choice between 75W-85 and 75W-90 often depends on the specific Nissan model, climate conditions, and driving style. Always consult your owner’s manual to determine the recommended viscosity grade for your vehicle. Using an incorrect viscosity can negatively impact shifting performance and transmission durability.
