I just got off Pennzoils website checking out their line of oils and it seems to me that the Platinum series, which is second in their line up, has better specs than the Ultra which is their best oil.
Yeah, I realize that the Ultra keeps my engine clean, but the spec sheets make it look like the Platinum is the better oil - it meets more, and modern specifications than the Ultra.
I just bought some Ultra to put in my Ecoboost F150 and after seeing all this, I'm thinking that the oil change after this one will be with the Platinum because it looks better on paper. Not many Ecoboost UOAs here and none on the EB engine using Ultra so I am at a loss.
I used both in my Mazdaspeed 3 with no problems but I'm sitting here wondering......
Any input guys?....
