Not all vehicles are compatible with this type of gear oil, so it is crucial to check your owner’s manual or consult a mechanic before making a purchase. Using the wrong type of gear oil can cause damage to your vehicle’s transmission or differential.

Look for API Certification

When buying any type of engine oil or lubricant, it is crucial to look for API (American Petroleum Institute) certification. This certification ensures that the product meets the industry standards and has been tested for quality and performance. Make sure the 75W90 synthetic gear oil you are purchasing has API certification.
