How much of what kind of oil

[Josh99]

Changing the oil in my truck this week sometime. I dont have an owners manual so I dont have the capacity. What would you guys suggest using as my oil? How often would you keep it changed? Thanks.

Your truck is a SD correct (99-03)? If so its 15 quarts with filter. I use Shell Rotella oil. Amsoil also is a good oil.

search button, everyone has there own opinion. but use a synthetic 5w40 if you live in a cooler climate, other than that run amsoil or rotella t syn

Rotella is the most popular and my UOA reports prove it is a excellent oil. Delo is second in poularity. I see no need for full synthetics. In order to get the extended miles on the oil you need a oil bypass system, and frequent UOA's, and changing the full flow filter every 3-5K, so the extra cost of all this easily balances out. I would rather change my oil every 3-5K. I do agree that using a lighter weight oil in cold climates is a good idea.

+1 on rotella and delo,no need what so ever to run synthetic in a powerstroke.

So which non-synthetic oils are available for a diesel that are any lower than 15w-40???? (For colder climate use)????

Wouldnt consider ashville a cold climate. I live down in the upstate sc and yall dont get 'cold' weather like out north/west plain areas do.

If you never see below zero temps you don't have to worry about cold.

I live in Florida, so I'm not worried about could. So go with something a little thicker than 5w-40?
