GC

[01cobravortech]

I'm a big fan of the German Castrol. I've used in my 03 Mustang Cobra and Blackstone Lab used oil analysis has shown lower wear with this oil opposed to that with Mobil 1 5w-30. Ran both oils for the same 5500 mile interval. I run GC for about 6000 miles in between oil changes now. Never saw a measurable improvement or decrease in fuel economy. My oil analysis says this is good stuff and this car isn't driven like a normal human being is behind the wheel.

A 10,000 mile OCI on a 4.6 using GC makes me want to try it in my 1996 Town Car. Did you ever get a UOA done on it?
