Does it meet the Chrysler spec yet?
The Chrysler spec may not be met by XM for political reasons after Fiat bought Chrysler, dumped M1 and went with Shell. However M1 will easily meet the spec. In fact many Chrysler dealers still carry M1 as many customers still ask for it.
this is what is on Mobil 1 site about this.
Question:
Mobil 1 5W-20 and Chrysler MS-6395
Why is your Mobil 1 5W-20 not Chrysler MS-6395 spec approved? Or if it is, why is the certification not on the bottle or website?

Answer:
Chrysler’s latest revision to the MS-6395 specification calls for a field trial spanning multiple seasons over two years. While we fully expect the exceptional performance of Mobil 1 synthetic motor oil to meet Chrysler’s specification requirements, at this time we are in the process of evaluating our timeline to start this testing

I have seen this before. The test involves a 2 year testing period which is silly IMO. How can oil producers fulfil all the testing the differant engine builders require when they change requirements so often.
