Sierra’s Oil is NMMA Certified, but why is that important?

April 14th, 2014 by SeaStar | No Comments » |

Marine gasoline engines have evolved through the years. Both two and four-stroke engines have a higher power output that places tough demands on an engines’ oil and lubricants. In order to assist boaters in choosing the best quality lubricants for their engine, the National Marine Manufacturers Association (NMMA) developed a program for the certification of these premium quality lubricants. The following is some information about the certifications that Sierra’s Oil has earned.

TC-W3 TWO-STROKE CERTIFICATION

The TC-W3® standard is based on performance. The various requirements include bench tests for fluidity, miscibility, rust, compatibility and so on. Engine tests are also performed to test the prevention of ring sticking and carbon buildup on pistons and other engine parts. The engine tests include one Johnson 40 HP, one Johnson 70 HP and two consecutive Mercury 15 HP tests. These engine tests are all run under severe conditions for 100 hours each.*

FC-W FOUR-STROKE CERTIFICATION

In conjunction with the NMMA, industry leaders in lubrication technology developed testing guidelines for marine four-stroke oil. These guidelines include bench tests for viscosity, corrosion, filter plugging, foaming and aeration. The oil must also pass a 100-hour general performance engine test.

So, why IS this important? NMMA certification proves that Sierra’s oil and lubricants provide the necessary performance and quality needed for today’s marine engines. You don’t need to sacrifice quality for a better cost any longer.
