Viscosity:
* SAE 10W-40 is the most common and recommended viscosity for the XR600R, especially in moderate climates.
* SAE 10W-30 can be used in colder weather for easier starting.
* SAE 20W-50 is suitable for hot climates or high-performance riding.
Type:
* Mineral oil: A budget-friendly option, but offers less protection than synthetics.
* Semi-synthetic: A good balance of performance and affordability.
* Full synthetic: The best performance and protection, but also the most expensive.
API Rating:
* Look for an API rating of SJ, SL, SM, or SN for a quality oil that meets modern standards.
Other Considerations:
* Wet clutch compatibility: Ensure the oil you choose is compatible with wet clutches. Most motorcycle-specific oils are, but it's always best to check the label.
* Engine wear protection: Look for oils with additives that offer good engine wear protection, such as ZDDP.
* Manufacturer Recommendations: Always check your XR600R's owner's manual for specific oil recommendations.
Popular Brands:

* Motul 300V: High-performance synthetic oil designed for racing.
