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?
-- Josh Eads, Cabot, AR
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.
