For a 2005 Ford F-250, it's generally recommended to use 5W-20 motor oil, especially for models equipped with the gasoline engine. If your F-250 has a diesel engine, such as the 6.0L Power Stroke, you should use 15W-40 oil. Always check the owner's manual for the specific recommendations based on your engine type and operating conditions.

You need 5W-30. The oil viscosity recommendation should be marked on your oil cap and in the owner's manual. Cheers
Use what the fill cap says, most are 5w20.
What do you mean by newer oil? If you are talking about the weight of the oil, use exactly what the owner's manual states. If it says use 5w30, then use 5w30. If you are referring to synthetic oil, yes you can use synthetic as long as you use the correct weight.
