We spend a lot of time validating our products. This is because we are responsible for entire propulsion systems – not just independent components. Everything (engines, transmissions, drives and propellers) must work together and be tolerant of each other. This includes oils and lubes. They are the system’s lifeblood.

We validate our engines using specific oil types and weights. Same goes for the drives and  lubes. Over the years, our two-stroke outboards have evolved from carbs to electronic fuel injection to OptiMax low-emissions direct fuel injected technology. Similarly, our higher horsepower sterndrives have evolved from traditional 2-valve, push rod engines to a quad cam, four valve engine of our own design. Oil and lube requirements have evolved along with the products.

Today, we offer our own line of 2-stroke and 4-stroke oils and gear lube. Mercury Racing 2-Stroke Engine Oil is recommended for our line of OptiMax outboards including the 250 SportXS and 300XS consumer outboards and 200XS SST and 200XS ROS race outboards. It is validated for use with standard and ProXS OptiMax models as well.

Mercury Racing 4-Stroke Engine Oil is vital to our sterndrive engines, from the 525 EFI to the all-new 1650 RACE. It is also recommended for use in the 350 SCi Verado outboard and is validated for use in all standard and Pro FourStroke Verados. Our 60 EFI FormulaRace outboard performs best when fed this enriched fluid as well.

Our all-new gear lube replaces a synthetic lube previously used on our high end surface drives. It is used in all gearcases built at Mercury Racing. Outboard gearcases include Fleet Master, Torque Master and Sport Master, IV SSM and VI SSM. Sterndrive gearcases include the dry-sump NXT1, NXT6 and M8 as well as Bravo One XR Sport Masters.

Mercury Racing oils and lube are available for purchase from your local Mercury Outboard or Mercury MerCruiser Sterndrive dealer. Part numbers are as follows:

  • 2-Stroke Engine Oil -1 U.S. Gallon: 92-8M0078011; MSRP $51.00 ea. (sold @ 3)
  • 4-Stroke Engine Oil -1 U.S. Gallon: 92-8M0078014; MSRP $41.45 ea. (sold @ 3)
  • Gear Lube – 1 Quart: 92-8M0078015; MSRP $18.32 ea. (sold @ 6)
  • Gear Lube – 5 U.S. Gallon: 92-8M0078016; MSRP $316.65

Protect your investment. Regular maintenance using factory approved oils and lubes will give you more hassle free time on the water and less in the service bay.

  1. For a 300XS, which oil is best to use? The Premium Plus or the DFI oil? I know the manual says Premium plus but I have spoke to several Merc techs and said that the DFI oil has better lubrication and is a cleaner running oil. I cannot get hold of the Mercury racing 2 stroke oil just yet.

    Thanks.

    1. Joe:

      Sorry for my delay in responding to you. The OptiMax 300XS was developed with the Premium Plus oil. We recommend that or the new Mercury Racing 2-stroke oil.

    1. Yes. The new Mercury Racing gear lube is appropriate for use in your SSM V drive as well. The outboard gearcases and sterndrives referenced in the article are all products currently produced at our facility.

  2. Is this the correct oil for a 2005 280 ROS 2 cycle? Has the packaging just changed?

    1. Brian,
      Yes. The new Mercury Racing 2-stroke oil is fit for use on the 2.5 EFI family of outboards. It replaces the Mercury Performance Blend Oil which is no longer available.
      Rick

  3. The Mercury Performance Blend 2-Cycle Outboard oil the above noted Mercury Racing 2 stroke is replacing (per your answer to question 3) was/is used in high rpm race engines (7000 to 9000 rpm). The above 2 stroke is a TCW3 rated oil. It is my understanding that the NMMA TCW3 specs are not at very high rpm for a TCW3 rating. What rpm is the above 2 stroke oil tested at and who tested it. Are there additional ratings for the new Mercury Racing 2 stroke oil that allows use at the racing high rpm?

    The Mercury Performance Plus 2 stroke oil is also TCW3 rated. I also see that oil noted for use in Mercury engines that are higher rpm like 6000 to 7000. Is this oil so much better than the standard specs to pass the NMMA TCW3 that it can be used at these higher rpms ?

  4. On a Merc 200XS ROS, requires what type of 2-stroke oil if kept below 7000 rpm. What would u recommend? What is the price at: 1 gal, 30 gal and 55 gal? They list a multifuel oil on the spec sheet at $100 a gal.
    I’m considering canceling my order. The over head cost with this is pricey. I do not race per say, I just like to have a little fun.

    1. Hi Brian. The 250 ProXB was a great engine. We built here at Mercury Racing. It was validated to run on Mercury TC-W3 Premium Plus oil. You can continue to run use that or our new Mercury Racing 2-stroke oil.

      1. I just repowered with a 250 ProXB, had a 2002 opti. Have about a gallon and a half of DFI oil in the remote tank. Do I need to drain it?

  5. I’m currently running a 2015 300xs and the dealer that sold me the boat told me to run dfi in my engine, now I was told to run 2 stroke racing oil.. What is the best oil for my engine?

  6. I have a 2016 300XS and I have a little DFI oil in the reservoir for test run, I’m going to run Mercury Racing Oil, is it
    OK the mix the two, or do I need to drain all the DFI oil out first?? Thanks

    1. Todd:
      As a general practice you want to minimize the mixing of any lubricants, but there are no known compatibility issues between the DFI oil and the Mercury Racing 2-stroke oil.
      Rick

  7. I have a 2016 300XS, the dealer put a little DFI oil in it for a test at the dealership to make sure everything was OK, can I mix the Racing Oil with the DFI oil, or do I need to drain the DFI out ?? thanks Todd

      1. Thanks for the reply. I called my local Mercury dealer and searched the Internet and can not seem to locate the 2 stroke racing oil. Any suggestion on where I might be able to purchase it?

        1. Hi Todd:
          Gosh – any Mercury dealer should be able to order the Mercury Racing 2-stroke oil. The part number is 92-8M0078011. It is sold in 1-gallon bottles; sold in multiples of three.
          Rick

  8. I just purchased a river boat with a 2016 Optimax 200 sportjet. I have heard a lot or negative comments on other blogs as to the lifespan of the engine. Do you recommend running the 2 stroke racing oil ? And any suggestions on improving the lifespan?

    Thanks
    Todd
