Preferred Oil....for 6.7

[Mason73]

Does anyone know what oil the factory fills these 6.7 up with at the factory? Is it the Motorcraft Synthetic Blend 10W-30, or something else? I am coming up on the first oil change and would like to use a Full Synthetic someday, but not yet! Also I have found the FL-2051 Motorcraft filters locally but I was thinking about using a WIX due to their great reputation. Just wondering what you guys are using out there and why?

My question would be even if WIX has a great reputation why go away from the factory filter?

WIX a great filter??? have you seen what happens to those things on a diesel? cost me TWO engines! a 7.3 and a 6.0. no pictures because i didnt use forums when these events took place

I beleive they come from the factory with 10-30 non synthetic. I have been running 15-40 until yesterday when I switched over to Valvoline Premium blue extreme for the winter at 9k miles. I would stick with the ford filter and get a filtermag.

valvoline syn 5-40*

I was told today they use a Synthetic Blend from the factory in the 2011 6.7's

Have not come up on my first oil change, so I am not 100% on that. If it is a Synthetic Blend from the factory, just stick with it if your motor is stock. Ford would not put something in their motors that they thought was not sufficient.

Thanks fellas for the feedback, I am gonna do the Motorcraft filter and the Motorcraft 15W-40.

running rotella T6 5-40 full syn, and factory filter, mechanic at dealership said man your using the best oil out there, I buy it at wally world and take it to them to change, mainly so that its in the computer that it is being changed, they say Ford as well as others are looking for ways to void warranties.

You did not get raped but I would not say the dealer did you any real favours based on retail pricing...
