Dave,
Thanks for the great response! As for my use of Semi-Syn oil, the T-Bird came from the factory with 5W20 Motorcraft Semi-Syn. I'm from the old school where we were taught not to use Full Syn before full engine break-in (5000 miles minimum.) I figured I'd use semi-syn until break-in is complete. Does that logic still hold up or is it an old wives tale?? Heck, I'll go full syn now if it's OK for the engine.
One other thing, you said you're using Amsoil 10W30. The recommended fill for the new T-Birds is 5W20. Are you concerned about any possible warranty issues due to using a heavier oil? I'd feel much better using a 10W30 full syn rather than a 5W20 weight. I'm just afraid I'll void my warranty.
Thanks,
A.J.
