Decoding the Specs: API-4 and SAE 90 Explained
Understanding the numbers and letters on your oil bottle is crucial. For yamalube motor gear oil 750ml api-4 sae 90, the “API-4” and “SAE 90” designations tell you a lot about its performance capabilities and viscosity.
What Does API-4 Mean for Gear Oil?
API stands for the American Petroleum Institute, and it sets performance standards for lubricants. The “GL” (Gear Lubricant) classifications, like GL-4, denote the type of service the gear oil is suitable for. API GL-4 gear oils are designed for moderate to severe operating conditions.
This means they contain specific additives, known as Extreme Pressure (EP) additives. These additives form a protective layer on gear surfaces, preventing metal-to-metal contact and scuffing, especially under heavy loads and high-stress situations. For the gearboxes found in many motorcycles and ATVs, GL-4 provides the necessary protection against pitting, scoring, and wear.
Understanding SAE 90 Viscosity
SAE stands for the Society of Automotive Engineers, and it defines the viscosity grades of oils. When you see “SAE 90” on gear oil, it’s important to note that this is a different scale than engine oil viscosity (e.g., SAE 30, 10W-40).
A gear oil with an SAE 90 rating is relatively thick. This higher viscosity is essential for gearboxes because it provides a robust film strength between gear teeth, which are subjected to immense pressure. This thick film helps cushion and protect the gear surfaces, preventing direct contact and reducing noise. It also ensures proper lubrication across a range of operating temperatures, from cold starts to fully warmed-up conditions.
Matching these specifications – API-4 and SAE 90 – to your vehicle’s manual is non-negotiable. Deviating from the recommended type can lead to inadequate lubrication, premature wear, and costly damage to your transmission or final drive unit.

- Shop rags or paper towels
- Brake cleaner or degreaser (for cleanup)
Step-by-Step Gear Oil Change Procedure
- Warm Up the Engine (Slightly): Run the engine for a few minutes. This warms the oil, making it thinner and allowing it to drain more completely. Do not get it excessively hot.
- Locate Drain and Fill Plugs: Consult your owner’s manual for the exact location of the gear oil drain plug and fill plug (or inspection bolt/sight glass) for your specific model. They are usually on the lower part of the transmission or final drive unit.
- Position the Drain Pan: Place your drain pan directly beneath the drain plug.
- Remove the Drain Plug: Using the correct wrench, carefully loosen and remove the drain plug. Be prepared for the oil to come out immediately, potentially hot. Allow all the old oil to drain completely. This can take several minutes.
- Inspect the Drain Plug: Many drain plugs are magnetic to catch metal shavings. Clean off any accumulated metal particles from the magnet. Inspect the drain plug washer (crush washer) for damage and replace it if necessary. This helps prevent leaks.
- Reinstall the Drain Plug: Once the oil has fully drained, reinstall the drain plug with a new crush washer if needed. Tighten it to the manufacturer’s specified torque using a torque wrench. Over-tightening can strip threads, while under-tightening can cause leaks.
- Fill with New Gear Oil: Locate the fill plug. Using your funnel, slowly add the new yamalube motor gear oil 750ml api-4 sae 90 into the fill hole. Refer to your owner’s manual for the exact capacity.
- Check the Oil Level: Most gearboxes have a specific method for checking the level:
- Sight Glass: Fill until the oil level is visible between the “min” and “max” lines in the sight glass.
- Fill-to-Spill: For some designs, you fill until the oil just begins to seep out of the fill hole.
- Dipstick: Remove a dipstick (if present), wipe it clean, reinsert it without threading (if applicable), and check the level.
- Reinstall the Fill Plug: Once the correct level is reached, reinstall the fill plug. Again, tighten it to the manufacturer’s specified torque.
- Clean Up: Wipe away any spilled oil from the gearbox and surrounding areas using shop rags and brake cleaner. Check for leaks around both plugs.
Following these yamalube motor gear oil 750ml api-4 sae 90 tips ensures a proper oil change, vital for your machine’s health.
