The Suzuki Gixxer 155CC is designed to run on regular unleaded gasoline with an octane rating of 91 or higher. Octane boosters are typically not necessary or recommended for motorcycles or vehicles that are designed to run on regular fuel.
Using a higher octane fuel or octane booster than required by the manufacturer is unlikely to provide any significant benefits in terms of performance or engine longevity. It is generally recommended to follow the fuel recommendations provided by the manufacturer to ensure optimal performance and fuel efficiency.
If you have any concerns about the fuel quality in your area or if you experience issues related to engine knocking or pinging, it is best to consult the owner's manual or contact a Suzuki authorized service center for specific recommendations regarding fuel additives or octane boosters that may be suitable for your Gixxer 155CC.
