For the Suzuki Gixxer 155 ABS 2019 model, Suzuki typically recommends using a high-quality four-stroke motorcycle engine oil that meets the specifications outlined in the owner's manual. While the exact oil recommendation may vary based on factors such as climate and riding conditions, Suzuki generally suggests using a mineral-based engine oil with the appropriate viscosity grade.
To determine the specific mineral engine oil suitable for your Suzuki Gixxer 155 ABS, I recommend referring to the owner's manual that came with your motorcycle. The manual should provide detailed information on the recommended engine oil specifications, including the appropriate viscosity grade (such as 10W-30, 10W-40, etc.) and any additional requirements or certifications.
If you don't have access to the owner's manual or need further assistance, I recommend contacting a Suzuki authorized service center or speaking with a Suzuki dealer. They will have the expertise to provide you with the most accurate and up-to-date information regarding the recommended mineral engine oil for your specific motorcycle model.
