The Suzuki Gixxer SF, including the older model from 2018, typically recommends using a 10W-40 engine oil. However, it's important to consult the owner's manual or contact a Suzuki authorized service center to confirm the specific oil recommendations for your motorcycle.
Regarding the type of oil (mineral, semi-synthetic, or full synthetic), here's a general guideline:
Mineral Oil: Mineral oil is the least expensive option and provides basic protection for the engine. It is suitable for regular commuting and short rides. However, it may require more frequent oil changes compared to synthetic oils.
Semi-Synthetic Oil: Semi-synthetic oil offers a balance between mineral and synthetic oils. It provides better protection and performance compared to mineral oil, making it suitable for moderate to heavy usage, longer rides, and varied riding conditions. It also offers improved engine cleanliness and longevity.
Full Synthetic Oil: Full synthetic oil provides the highest level of protection and performance. It offers superior lubrication, better heat resistance, and enhanced engine cleanliness. Full synthetic oil is recommended for high-performance motorcycles, extreme riding conditions, and prolonged usage. It is generally more expensive than mineral and semi-synthetic oils.
Considering the Suzuki Gixxer SF is a sporty motorcycle, using a semi-synthetic or full synthetic oil would be a good choice. It provides better lubrication and protection, especially during demanding riding conditions. However, if you prefer to stick with mineral oil due to budget constraints or other reasons, ensure that you follow the recommended oil change intervals more diligently.
Remember to refer to the owner's manual or consult a Suzuki authorized service center to get the most accurate and up-to-date information regarding the suitable engine oil type and grade for your specific model and local climate conditions.
