I run my v6 cougar with the "upgraded" oil pan and AMSOIL 0W-30 synthetic oil. This oil has more "hang" than standard. Meaning that there is more lubricant up on vital engine points longer.. It doesn't find its way back into the pan near as fast as dino oil.
If you use synthetic oil (and you should),be careful as this "hang" probity can cause you to really overfill. Measure the volume of oil you add, not by looking at what is shown on the oil dip stick..
