well its time to change my oil and wondering what brand/type oil is the best for the 4.6l. ive always used pensoil 5w-20 but been looking st royal purple and ect. has anyone tried any other oils on the 4.6 if so whats the deal!!! thanks for every ones help..

I use mobil 1 syn 5-20

Royal purple is nice, but i don't see the point in an everyday driver. I might eventually change the diff/trans to royal purple put i'm not putting that much money into an oil change

 

The Motorcraft 5W20 is a synthetic blend and is available at Wal-Mart at a good price along with the Motorcraft oil filter. Why waste money or the other stuff?

 

Motorcraft is designed for the Ford engines so..

I use the 5w20 with the motorcraft filter.

 

Any 5w20 synthetic will do. If you want to save some money use MC, it's great oil. As for filter, MC FL-820s, Purolator Pure one or Wix are great filters. I don't use the Fram brand, Fram oil filter quality is questionnable, but their filter won't damage your engine if you choose to use one.

 

i went to autozone and they gave me the motorcraft filter fl-400s is this the correct one its a 4.6l? dont want to change it then for it not to fit...

 

As I mentionned in my previous post, you need MC FL-820s. I think the MC FL- 400s is for the V6 engine.
