They offer a mineral and synthetic blend 4-stroke oil. Now, after investing five years in development, Mercury has just formulated the two families of mineral base and synthetic blend into new 4-stroke engine oils to replace all previous lines. At one time, Mercury offered up to six different 4-stroke engine oils, being marketed under both the Mercury and Quicksilver brand. As Mercury introduced their 4-stroke outboards they created both mineral based and synthetic lubricants to best provide necessary performance for those engines. Those products have undergone improvements over time. Mercury Marine has offered premium 4-stroke engine oils under both the Quicksilver and Mercury brands since they introduced the MerCruiser Stern Drive. It needs to be slippery yet be able to stick or adhere to the internal engine surfaces to help protect them from corrosion in our very water friendly environment. Your engine oil needs to lubricate and protect the engine from corrosion. Filter plugging testing to ensure flow.Intended for all gasoline-powered marine applications.Outboard engine test to ensure overall performance, no scuffing, spalling, scoring or wear combined with reduced carbon deposits, varnish, sludge or other "distress".Shear stability testing including High Temperature-High Shear tests.Make sure to look for the NMMA "bug" on the bottle.
#Mercury motor oil update
For the four-cycle engines the most recent update is FC-W Catalyst Compatible "FC-W" (Four Cycle, Water-cooled). For two-cycle oils that now is TC-W3 (two-cycle, water-cooled, version #3). Mercury Marine offers 4-stroke lubricants under their Mercury and Quicksilver brands while Yamaha has Yamalube, Bombardier (SeaDoo) has the XPS line and other engine manufacturers offer premium quality oils.Įach "marine grade" engine oil must pass National Marine Manufacturers Association (NMMA) requirements. Engine failure and possible warranty claims cost the dealer and engine manufacturer a lot of money. And, other than for periodic maintenance, the local dealer doesn?t want to see that engine back in their shop, in particular, for warranty work. Once an engine leaves the factory, the manufacturer really never wants to see it again. That's great for the boater and in all honesty, self-serving for the manufacturer. Over the decades, marine engine manufacturers have marketed what they felt were the best lubricants for their engines.

They always are pushing, even when at idle for trolling or slow cruising. Unlike the automotive application, marine engines never get to coast along the waterway. Stern drive power preference will continue for many but outboards are far outpacing stern drive sales for now.Īs was learned with stern drive powered boats, the engine must have good lubrication to keep running efficiently and simply to keep running.Īny marine engine experiences the same operational stresses. With the introduction of four cycle outboards recreational boating power changed forever and many say, for the better. Stern drives dominated the family bowrider and recreational boating market for decades. Stern drive powered boats have used modified (gasoline or diesel automotive engines, gasoline engines being four cycle) since their inception. With the takeover of four cycle/four stroke outboards the use of top quality oil to lubricate and protect your engine is more important than ever.
