What would be the best possible, its got 87k original miles and I'm looking for something to improve performance. Would Royal Purple 5w-30 High Performance work or be bad to use?

I use Shell Rotella T 15W-40. It still has zinc in it. Zinc is needed to protect the flat tappet cam shaft that ford used in the engines.

AMSOIL has a new ZRod oil that has the sync you need to keep those flat tapets looking good.

Castrol GTX 20w50 on my 289 I think the same applies to the 200

manual says 10w 30 for colder climates, and 20w40 for warmer (20w50 is the closest available)
