I have a 2017 Jeep Patriot that calls for a synthetic oil approved to MS 6395. Always been particular to Castrol, so my first change I used Castro Edge Syntec which lists MS 6395. Now to my second oil change: The new Castrol label, which says it replaces Syntec is called Edge Titanium. It does NOT list MS 6395. So evidently, they changed the formula. Why the difference? Owners manual calls for MS 6395 and I'd like to stick with that and really don't want to leave Castrol. Any thoughts on how the formula is different?
