I like the following:
1. Valvoline Maxlife 5W30 or Valvoline Maxlife NextGen 5W30 (same thing really). It's a synthetic blend oil formulated for older cars with a _strong_ additives packages (better than average detergents, anti-wear, seal conditioners, etc).
2. Mobil 1 HW 5W30 (for high mileage cars).
3. Mobile Super 5000 or Mobile Super 5000 HM. This is a conventional motor oil good for at least 5000 miles. Very cheap at walmart ($14 for a jug). Very good used analysis reports.
Having said this, I think any major brand (Peak, Mobil, Castrol, Valvoline, etc) or store band (walmart, autozone, napa, etc) conversational should work just fine and last at least 5000 miles easily. In fact, today Ford recommends 5000 mile oil changes for severe service duty and 7500 oil change internal for normal duty as long as the oil meets Ford's Ford-WSS-M2C930-A/ Ford-WSS-M2C945-A specifications (pretty much any major brand conventional does, as well as syn blend, and synthetic oils).
