It seems suspicious too that Shell stopped selling their Nautilus 25W40 a
few years ago (for $20/4L jug) while Merc cruiser's oil has made significant
advances in marketing on the shelves (at $36+). I wonder if Shell sold
their formulation out to Merc cruiser, who is now adding in the traditional
huge markup because it is marine?

I think I will be switching to straight 30W oil! Thanks to everyone for
their input / feedback.

25W40

Why not look in the manual?
http://www.mercurymarine.com/fueloil...mendation_faqs

"NOTE: The use of non-detergent oils, multi-viscosity oils (other than as
specified), non-FC-W rated synthetic oils, low quality oils or oils that
contain solid additives are specifically not recommended."

The FC-W rating is at:

Of course, at $40/gallon for MY oil, I'd sure recommend you buy only MY
oil from ME, too! Searching for these URLs on Google has revealed some
halibut to me that makes me suspicious.....

Not a single webpage from ANY real oil company (those with a real
refinery, not just a bottling plant like Amsoil, who has 20 webpages
about FC-W wonders and NO REFINERY), says anything about FC-W oil. Not
Exxon-Mobil, Not Texaco, Not Chevron, NONE. This rings my bell and
lights up the "SCAM!" light, here. Search Google for yourselves. Don't
take my word for it.

Remember NMMA is "them", not an independent certification and testing
company like UL. NMMA never says, "this marine manufacturer's stuff just
sucks and you shouldn't buy it." They love every product their members
ever produce, even the Bayliners with pop rivets holding the doors on and
all the chopper gun boats...(c;

(Any Amsoil dealers watching that can point out the exact address of the
AMSOIL REFINERY for me?)
