ECOTIP #2: Preventing and Cleaning Spills

Wednesday, September 20th, 2017


Picture this, you’re enjoying your day out on the water when you see a rainbow looking film on the water. You think, “Oh no! Is that from me?”. Day ruined. 

Take a look at some tips that we’ve found from our friends at so there is no worries next time you’re out and about!


  1. Spill-proof your oil changes: Use an oil change pump to transfer oil to a spill-proof container. Wrap an absorbent pad around the oil filter to prevent oil from spilling into the bilge
  2. Fueling up: Prevent fuel spills by filling fuel tanks slowly and use absorbent pads or reusable rags to catch drips or clean up spills. Don’t “top off” your tank, remember fuel expands as it gets warm, so leave about 10% empty.
  3. CLEAN IT UP: Never use soap to disperse fuel and oil spills. Not only is it harmful to the environment, it is also illegal.
  4. Maintenance on land: Try (as much as possible) to do all maintenance projects in the boatyard instead of on the water. If you do have to do maintenance on the water, use tarps and vacuum sanders to collect all debris for proper disposal.
  5. “Stow it, don’t throw it!”: Keep your trash on board! Never throw any type of garbage into the ocean and take advantage of shore-side facilities to recycle plastic, glass, metal, and paper. Sometimes, the wind picks up and blows out trash you were trying to keep on board. Try this cool trick to wind-proof your trash can. (Adapt the instructions for your particular size of trash can.)

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

Monday, April 14th, 2014

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.


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.*


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.
