FAQ

• Q: What are Yellow Metals?
• Yellow Metals refer to components or parts made of non-ferrous metals such as brass, bronze, or copper.
• Q: Can I use MT80W in my automatic transmission?
• No, MT80W is specifically designed for manual transmissions and should not be used in automatic transmissions.
• Q: Can I use HD-X 80W90 in a differential with Limited Slip?
• No, HD-X 80W90 is intended for differentials without mechanical Limited Slip. If your differential has Limited Slip, you should use MOTYLGEAR LS 80W90 or a suitable lubricant recommended by the manufacturer.
• Q: Can I use Gear 300 75W90 on my motorcycle?
• Gear 300 75W90 is primarily designed for racing or passenger car applications. For motorcycles, you should refer to the manufacturer’s recommendations and use a lubricant specifically formulated for motorcycles.
• Q: Can I mix different Motul gear oils?
• It is generally not recommended to mix different types or grades of gear oils. Mixing different gear oils can lead to unpredictable performance and may not provide the desired lubrication properties. It is best to use a single type and grade of gear oil as recommended by the manufacturer.
