I just bought a '94 Ford E150 Chateau Club wagon with 137K miles on it. It looks to have been well cared for. I bought it from the original owner who had it serviced regularly by the dealer since it was new. He has been running the factory "Preferred" 5W30. Should I stay with 5W30? Should I go to a high mileage oil. My other van is a '78 Dodge 318 with 200K mi on the engine. I always used Castrol 20-50 and recently switched to Castrol High Mileage 20-50. My driving is in the Western states. I don't tow anything and the van is only moderately loaded with 2 people and their gear.
