Four-Stroke Marine Engine Oils: Good, Better, Bestġ0W-30 Mineral 4-Stroke Marine Engine Oil provides outstanding lubricity for internal engine components to reduce wear, scuffing and scoring for improved long-term reliability, making it a good choice for Mercury and other brand four-stroke outboard engines.

It provides maximum protection for OptiMax and DFI engines, outperforming other oils by combining a modified base stock blend with a synthetic additive package that provides superior resistance to piston scuffing, minimizes carbon build-up and helps maintain engine top-end speed and acceleration. OptiMax Synthetic Blend two-stroke engine oil was developed to meet the needs of Mercury OptiMax® and direct fuel-injected (DFI) two-stroke outboard engines. Its clean-burning formula reduces carbon build-up in exhaust systems and provides superior lubrication in premix or oil-injected two-stroke applications.
#QUICKSILVER GEAR LUBE PLUS#
With a higher concentration marine additive package, Premium Plus 2-Stroke Marine Engine Oil Synthetic Blend is formulated for high-horsepower two-stroke outboards, including direct fuel-injected engines. It reduces rust and corrosion of internal components and meets or exceeds all outboard and personal watercraft manufacturers’ recommendations for use of TC-W2® and TC-W3® oils in premix and oil-injected two-stroke applications. Premium 2-Stroke Engine Oil is formulated to meet the needs of low- to mid-horsepower two-stroke outboard engines under general marine operating conditions. In this guide, we’ll take a closer look at the wide variety of oils and gear lubes offered in the Mercury Precision Lubricants product line to help you select the best choice for your engine or gearcase. The first engine manufacturer to develop oils that meet the National Marine Manufacturers Association® (NMMA) FC-W® standards for all four-stroke engines, Mercury rigorously tests its Precision Lubricants products to meet our high standards to protect your outboard, inboard or sterndrive engine and provide many years of reliable service and fun on the water. Recognizing these demands, Mercury Precision Lubricants® products are formulated to meet the unique needs of marine engines with specially designed additives that reduce friction and protect against engine wear and internal corrosion. When not on the water, marine engines often sit in storage for long periods of disuse during the off-season.

Marine engines frequently run for extended periods of time at high rpm or wide-open throttle, often in corrosive saltwater. Boating is one of the most demanding environments in which an engine can operate.
