MPR Injector is a fully synthetic high performance 2 stroke marine lubricant. It is most suited for use in an injector system but can be used as a premix oil. MPR Injector is a smokeless, ultra clean burning lubricant with exceptional performance which offers complete protection to the engine. It will mix with leaded or unleaded petrol, avgas and octane boosters, but not methanol or castor based oils. MPR Injector meets the requirements of Sea-Doo jet skis and other Rotax engined marine equipment where 'low ash' oils rather than 'ashless' oils are required. Use up to 50:1 and always follow the manufacturers recommendation.
