All four Amsoil products would be fine.

Fewer oils these days are true GRP IV. PAO Synthetics. But these all are.
Any of these along with M-1 V-Twin and M-1 15W-50 SilverCap are great choices.

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.

Hydro - any downside to running Valvoline 40 Racing conventional oil? 540's NA, temp never above 180. Engine builder wants to stay with this oil. Using a Wix filter. Thanks.

I only have a couple minutes to do this today so I will do it quick and dirty....these are products OSO members have used and have enjoyed much success with.
Some go with all Mercury products; others with M-1 or Amsoil and some mix and match.
My personal picks are in bold.
Synthetic oil:
-Amsoil Racing Severe Service 20W-50
-Mobil-1 15W-50 EP
-Mobil-1 20W-50 V-Twin
-Royal Purple 20W-50
-Redline 20W-50

I was wondering if someone could shed some light on the FC-W rated oil.
When I read about oil in our Merc 4986HO Manual they have a note "....., non FC-W rated synthetic oils,.... are specifically not recommended."
What is FC-W rated oil? What does it do?
It seems only Mercury/Quicksilver oil has this rating. A little confused as to why.
Thanks for the help.

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.
