Hi BR,
Virgin oil analysis, knowledge and an interest + lots of pretty boring research. On the subject of mercury do they manufacturer here?? Their manufacture for the US products is pretty well documented and as in all oil they are done to the required spec, there is also many instances where oil products are simply re-branded with new colourisation being the last pour from the Vat so to speak. ATM cabellas has quality mercury oil for sale as their own house brand.
The Yamaha site indicates that the oil has "additives" namely- "Rust, Corrosion, and Deposit Protection: The additive package is formulated to fight corrosion, varnish, and wear for longer engine life".
Is this merely marketing blurb or does the Caltex oil supplied to Yamaha have additional components for operation in a marine environment?
In this instance entirely marketing but usualy yes it is largely marketing, some oils do do a better job than others even within the confines of the TCW3 spec and good ones get identified sooner or later.
Cheers
