Finally got ahold of Mobil 1's european formula 0w-40, and not sure but I believe the European Duratec's are using it. Chain noise at start up cold or hot now less than a 1/4 second. Since Porsche designed this motor, it seems only right to treat it to the good stuff. 5 years old and at least 10 more to go.
No more snake oil Syntec after Castrol's engineers blew me off when I complained about all the lamp black in the valve-train area. (Two oil changes in 9 months) So much for their fallacious synthetic.
One thing to remember, It's your car, your money whatever makes you feel good do it. The oil companies are out to make a buck and since loyality has went by the way-side, buyer beware! Even if you had your own lab, time and money, you'd probalbly realize it's mostly "marketing hype".
While I can still afford Mobil 1 this is what I'm using in my Duratec and my John Deere.
