I take it you're running synthetic oil? Certainly hope so if you're hoping to get 10k out of it....I change the oil, 5/20 viscosity, every 3,000 miles. I generally go to Firestone or Goodyear for my oil changes. I was told the oil will last for 10,000 mi. before it breaks down but the filter gets clogged in about 3,000 mi.
