I'm getting the feeling that XOM is done doing any favours for Chrysler. M1 doesn't meet their most basic specification (even though their conventional does). They don't offer an oil meeting this Fiat based Chrysler specification, either. I know that at least some of their oils list Fiat specification numbers.
I just doubt that XOM is going to put a lot of effort into obtaining the basic Chrysler specification, the SRT spec, or this Fiat based spec. Agip might as well start marketing hard in North America. After all, SOPUS isn't going to put much effort into getting these products out there except to dealers.
In a few years, as I said before, Fiat will be fed up, Tata Motors will pick up the pieces, and Chryslers will be calling for SF rated monogrades, and people will struggle to find those, too.
