It's an NMMA certification for oils. Happy reading: http://www.nmma.org/certification/lo...nual_9-06_.pdf
Amsoil Marine has an FC-W rating, maybe others as well. Mercury doesn't have a monopoly on that market.

Thanks for the link.

I was asked to do a brief 2010 lubrication recommendation.
#1. Do not use SM rated oils as they have too little ZDDP. Mobil-1 20W-50 V-Twin is still the one to beat. Royal Purple, Amsoil V-Twin and Redline 20W-50 are amazing as well.
$2.Use a Wix oil filter or Mercury racing oil filter and you will have the best combination.
#3. Mercury 20W-40 Synthetic Blend is an outstanding oil!
#4. If you run hard change often. Synthetic in a boat engine is not for extended drains...it's for better heat protection and extendedbearing life.
#5. Castrol/Kendall/Valvoline SL rated oils 20W-50 are excellent.

In order to assure quality control, the marketer must enter
into and comply with a licensing agreement with NMMA, including payment of an annual fee, as established by NMMA Oil Certification Committee.

Hello all!
I received several PM's to continue the Marine Lubrication Thread in light of the many changes (good and not so good in the oil industry) for marine engines lately.
Perhaps a good place to begin is to make mention of what a Marine Offshore Oil ought to be:
-The right viscosity for the climate and type of service for lubrication on startup and full operating temperature.
-A high potency detergency additive package to prevent sludge.
-Anti-wear additives to cope with the high shearing forces when using engines at or near maximum RPM.
-Perhaps the single factor that seperates a true marine oil from an automotive oil is that a good marine oil needs to address the additional amount of moisture/condensation present in significant amounts in engines exposed to this type of environment and set up with wet exhaust and the potential for some reversion as well. Leave an engine sit around for a year in a boat yard and wonder why it won't start and maybe needs to be rebuilt? Corrosion.
-Forget extending oil changes in the marine envoronment and this especially goes for super-charged engines subject to fuel dilution.
That should be a refresher for what the "tall order" for an Offshore Engine Oil.
To be continued.

Good Choice??

This is along with the new Amsoil EA filter. Just think the high TBN is good for the winter storage.

I have been running Amsoil 15W40 Diesel and Marine oil in my mild modified 350hp 355cu for the past 7 years and have no issues. Is this a good choice or is there a better one??

This oil has specific additives to prevent corrosion that occurs from condensation when an engine sits out in the boat yard. Amsoil buys their base stok synthetic oil from Mobil and their "better oils" are Group Iv. as this one is.
The Amsoil EaO oil filter is made by Donaldson and has a heavy case that withstands high pressure very well and it is amoung the best in particulate filtration.
I feel this is a great oil for engines up to 454 cubes that are not heavilly modified. Bigger engines shear oils down and you might be better advised to use a 20W-50 Synthetic.
