Nope, Shell provides all lubricants/oil for Chrysler, according to a Shell corp. I just talked to, and then everything is re-branded for Chrysler specifics. I have Chrysler checking for the MSDS now lol. Even a couple dealerships didn't have the MSDS *eye roll*
In general, I think the baseline is in Viscosities which is why you see those number don't tend to vary at all and why you see Viscosity always advertised, but Flashpoints and other values can vary quite a bit. So far Redline, Amsoil, and Royal Purple seem to be the better tiered.
