 because I still see that's where the problems are, even though people won't agree with me. But from the guy in the bay that sees the engine failures and sees the cost of engine repair, I still think an oil change done in a timely manner, done correctly. So I think a conventional oil filter for what you're doing in the 5,000-mile range and the 6,000, 7,000-mile range, I think you're fine. I always go back to this.
