The recommended drain intervals for engine oil can vary depending on factors such as the specific motorcycle model, riding conditions, and the type of oil being used. It's essential to consult the owner's manual or reach out to the manufacturer or authorized service center for accurate information regarding the drain interval for your Yamaha MT15 1.0.
Regarding Motul engine oils, here's some general information:
Motul 7100 10W40: The Motul 7100 is a fully synthetic engine oil designed for high-performance motorcycles. The drain interval for this oil can vary, but it is typically recommended to change the oil every 3,000 to 5,000 kilometers or every 6 months, whichever comes first. However, it's crucial to refer to the specific recommendations mentioned in the owner's manual or seek guidance from Yamaha or Motul for the exact drain interval.
Motul 5100 10W40: The Motul 5100 is a semi-synthetic engine oil suitable for a wide range of motorcycles. The drain interval for this oil is generally similar to that of the Motul 7100, around 3,000 to 5,000 kilometers or every 6 months. Again, it's important to refer to the specific recommendations provided by the manufacturer.
Regarding using 10W50 oil, it's best to follow the manufacturer's recommendations for your specific motorcycle model. Yamaha provides detailed information about the recommended viscosity and oil type in the owner's manual. Using a different viscosity than what is recommended can impact engine performance and potentially lead to engine damage.
If you're uncertain about the best oil choice or drain interval for your Yamaha MT15 1.0, I recommend reaching out to Yamaha's customer service or an authorized Yamaha service center. They can provide you with the most accurate and up-to-date information based on your specific motorcycle model and local conditions.
