This new synthetic blend oil was developed specifically for the greater demands of DFI outboard engines. Higher operating temperatures combined with reduced oiling rates have put increased demands on the lubricants. This exclusive new formula provides increased lubricity while minimizing carbon deposits, helps reduce smoke and provides the highest protection for the engine. Not intended to be used in all applications specifying a TC-W3 oil. NOTE:Mercury Optimax/DFI oil is recommended for use in Mercury and Mariner Optimax and direct fuel injected DFI 2-cycle outboards • Maximizes the performance of Mercury and Mariner Optimax and DFI engines where reduced oiling rates and higher operating temperatures put increased demands on lubricants • Synthetic additives provide increased lubricity and resistance to scuffing
