Product Details

This Quicksilver 858039Q01 is a synthetic blend 2-cycle engine oil specifically formulated to meet the needs of OptiMax and Direct Fuel Injected (DFI) 2-cycle outboard engines. It provides maximum protection for OptiMax and DFI engines even under the most extreme operating conditions. The higher operating temperatures and reduced oiling rates of today's 2-cycle outboards have put greater demands on the lubricants used in them.

Key Features:

  • Outperforms other oils by combining a carefully modified base stock blend with a synthetic additive package
  • Minimizes carbon build-up to help maintain engine top end speed and acceleration
  • Superior lubrication for increased resistance to piston scuffing
  • Provides warranty protection for Mercury and Mariner OptiMax and DFI Outboards
  • Fights carbon deposits to help reduce smoke and provide the highest protection for your 2-cycle outboard engine

This Direct Injection Engine Oil is recommended for use in DFI Mercury, Mariner, Optimax outboards and DFI two-cycle engines. The convenient 55-gallon drum (208 liter) capacity is ideal for marine service facilities, commercial operations, and high-volume users who demand consistent performance and protection for their outboard engines.

Note: Not intended for use in any engines requiring TC-W3 oil.
