 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. Think of how many cars are on the road in the country at any given time and how many cars are driven and the oil changes are done in that 5,000 to 7,000-mile interval. Conventional filters, oil that meets manufacturer specs, and you don't see engine failures.
