Best method to flush out engine oil from filter to pan for a 6.4 power stroke 2008. What to use as well.

Thank you,

What is it you're trying to do? Did something go wrong? Are you worried there's stuff floating around in there? Synthetic oil is a really good cleaner with good detergents, if something came apart, buy some really strong small magnets to stick on the oil pan all over to hopefully grab stuff floating around in there.
