Oil Change (How Often?)

[NovaScotiaF350]

After how many miles should I change my oil in my 6.0L if it was last changed using conventional oil? and I plan on using Valvoline Premium Blue full synthetic for the next change, how many miles would I be able to get out of that?

Thanks.

5000 miles is what Ford recommends on oil changes. I run Rotella Syn oil and I still change it every 5000 miles. If you go longer you will have to get a better filtration system and get your oil checked by a laboratory. Look into a bypass filter system. Many of our sponsor carry them.

I change mine every 5,000 km. Some may say it's overkill but oil is cheap compared to a new motor!

i did use that oil for a bit, but never went farther then 7500km(that is usually my oil change interval)

Stick to the recommended oil change interval unless you run a bypass filter system, and back it up with analysis. Synthetic or conventional, without a bypass filter setup, you can't extend the oil interval without running the risk of injector problems. Remember these injectors use high pressure engine oil for fuel injection, so if you run dirty oil, you get injection trouble. Dirty oil will increase the possibility of injector stiction in cold weather. Probably the best single thing you can do to ensure trouble free operation with a 6.0 is regular oil changes. Synthetic, and bypass filtration will only increase your reliability.
