[QUOTE="Krace, post: 12290137, member: 142108"] From my understanding why Ford picked the 5W-20 oil for the 5.0 gt. Is from the lower 7000 rpm and the use of oil squirters. And when you push this motor over that 7000 rpm the oil has a harder time getting to the heads because of the lower oil pressure the squirters are producing at higher rpm. Now if you run 5w-50, the oil is to thick for the squirters to cool the pistons at the higher rpms. But the heads will be getting the right amount of oil it needs. Thats why Ford removed the oil squirters from the Boss and added better rods, pistons and 5w-50 to accommodate the heat from not having the squirters. And now have the ability to run it at higher rpm's to produce more hp. Now if you are like me and run the Boss302 intake manifold and run this motor up to 7500 rpm. Keep the 5w-20 and run the boss 302 oil cooler and radiator. (You have to run the bigger radiator also with the oil cooler to take on the extra heat from the oil or you are just transferring the extra heat from the oil to the coolant and not getting anywhere) This will help with keeping the oil cool and it will run a bit thicker because of it. Thus having the right velocity oil for the squirters and getting enough oil to the heads at the higher rpm range. When modding a motor to do something it was not meant for, I think about longevity as well not just what power i can pull out of it for the time being. [/QUOTE]
