the biggest key to oil changes is not necesarily brand but do not go over the intervals need to keep it fresh, motorcraft or rotella is what ive always used

[dusted4eva]

Amsoil 5w 30 and amsoil filter.

I run Rotella Syn 5W40 and have for about 50k miles. It starts great in the winter and the OA have come back great. I do my oil changes about 5500 miles on that oil. I wouldn't recommend 10000 OCI unless you do an oil analysis half way through to prove that the oil hasn't sheared.
