Was wondering if anyone knows if there is a big differance between Castrol Edge and Edge Titanium? I'm going to use it in my 2002 E39 525i Sport Wagon. I have been using Mobil one but want to change over to Castrol.
As long as they both meet BMW LL-01 or ACEA A3/B4, I wouldn't worry which one you use. Anything in the marketingese is just noise compared to actually meeting BMW standards.
I figured that was checking to see if anyone had looked into it more then I did. Also it's curious that they don't sell the titanium in the more efficient 5+quart container,
