If any of the Chrysler Technicians reading this can find out, I would like to know what Chrysler Material Spec MS-6395 actually says and specifies. I suspect it provides for lower volatility and possibly higher High Temp High Shear numbers ("HTHS")than the current API SM category provides, but I'm speculating.
e-mail me off-line if appropriate. Even a lead as to whom I might contact about this would be good.
Thanks....Phil
