I know a mechanic that works at ford. He said these trucks are designed to run with motorcraft oil and that's all I should run in my truck. Why do I see a lot of you guys using different oil? Is there a drawback to using motorcraft? I've only ever used motorcraft in my truck and with 175,xxx on the clock its still running as strong as the day I bought it.
