Re: tcw2 or tcw3
well....octane in gasoline...decarbing outboards...now oil price/quality....GAWD I CANT BE QUIET!!!!! for anyone willing to listen to ANOTHER diatribe by the oddd1, here goes....tcw2 oil was around for years and worked well in the relatively low stress/decent fuel era it came from.......once fuel qualities changed [for the EPA and the auto manufacturers] the manufacturers of 2 cycle outboards were saddled with an alarming increase in warrantee failures....for whatever reason,piston scuffing, ring coking, carbon buildup....the end result is a recomendation to use a better quality oil to retard these problems.....hence the nmma/obc designation of a oil with an enhanced additive package, TCW-3...<br />Now, if your an oil company that needs to market your oil at a tcw3 rating to be competetive in the market, do you add a enough compound "X" to just get by the ratings minimum spec or enough to protect the engine?????<br />and once you get a tcw3 rating from the API or SAE {i forget} do you maintain that level of expensive compound "X" or maybe slide just under minimums...heck whos watching???<br /> now, if you are a engine manufacturer and warrantee your engines/oil would you flirt with the minimum spec or go with a safe margin of compound "X" in your blend???? Christ we are already charging dealer prices for it..it better be good....would be awful embarassing haveing our motors failing on our oil....<br />you can argue with this line of reasoning all you want, human nature will eventually prevail...people will usually do what you expect of them, an money certainly makes the world go round....LOL...
