And you can tell Ford you're still running a 5w20.

Nice improvement.

It is very interesting that good old Havoline dino 5W30 improved things slightly over the MC 5W20. It did shear down, but who cares if the numbers turn out this good? I have an older 5.4L Expy that I had switched over to MC 5W20 from Havoine 5W30. After seeing this UOA....I think I will switch back. I think it is difficult to be Havoline for UOAs and $/quart.

Thanks for sharing.

Check the silicon. It may not just be the oil. The air filter change or conditions could be the difference.

I am not sure if it was the air filter or MC --> Havoline ... Might go back to MC 5w-20 and see what I get.

Guys, I have never tried Havoline 5w30 in my piston slapper suburban but am thinking about doing it with a 3000 mi OCI any thoughts?
