The V-Twin is a much better oil at 210F, at 99.8 SUS it is a solid 50 and the anti wear,(zinc & phosphorus) are a bit higher. A typical PCMO (passenger car motor oil) has Z&P levels around 1000PPM or less.
Remember Z&P are sacraficial, the PPM drops as the oil is used. The flash point for the V-Twin is higher because the viscosity of the oil has the other fluids beat by a longshot. Probably a heavier centistoke PAO basestock. Ken I read where V-Twin is a 100% GRP V. base stock PAO derived oil Many of the 2008 automobile oils (conv. and syn) now have zinc and phos in the 600-700 ppm range. Not good for marine use. Before you use something send it in for testing first if it's not posted here or on another site. Oil's I would use for marine use: Merc 25W-40 semi syn M-1 Gold Cap M-1 V-Twin RP 20W-50 Redline 20W-50 Amsoil Series 2000 20W-50 Amsoil 15W-40 Marine and Diesel 15W-40 Rotella Penzoil 20W-50 Quaker State 20W-50 |
It's also interesting to note that V-Twin has high level of magnesium and low phos. and calcium levels as part of it's anti-wear additive package. It's a less "slick oil".
It obviously is worth the extra buck or so inlight of recent reformulations. |
I was asked what to use in a car requiring 10W-30/5W-30 or
0W30, This oil is new and regarded as one of the best. https://www.amsoil.com/storefront/sso.aspx |
Only Europen automobile oil made in N. America. Works well in BMW's I hear.
