Castrol Syntec meets the Chrysler MS6395 spec. Mobil one doesn't have the stamp. I'm also not worried about my dealer analyzing my oil to see what kind of oil I put in. I'm worried that when I have to provide proof of oil changes at the recommended intervals that my receipt for the oil will list an oil that meets the spec. If I provide them with a receipt for 7 quarts of Mobil 1 and they want to be jerks about it, I don't want them saying that since my oil didn't meet the specs they won't warranty my engine. Mobil 1 would probably stand behind their oil, but it isn't worth the hassle to find out when their is another alternative. I found the Castrol at Walmart in 5 gallon jugs and quart bottles. That's likely what my first oil change will be with.
