  • ENEOS RACING SPEC PRO-2T (SAITO STANDARD) etc.
• If such oils are not available in your country, then please ask the official SAITO distributor in your country for an alternative.
• Be sure to use the mixture: gasoline : oil = 15-20 : 1 -  by volume ratio. (Example 1000ml of gasoline should be mixed with more than 50ml of oil).
• During the break-in process, use 15:1 (6.25%) mixed fuel to ensure the best lubrication for initial running.

• Do not use gasoline containing ethanol. It may cause not only power loss but also corrosion inside the engine.
