me too!

 

I'm going to pretend the F150 is my Jeep Comanche and run Mobil1 15w-50 in it. That should end the discussion as well as help it run like the jeep. Note, the Jeep was the last AMC Jeep with the AMC 4.0L not CHRYSLER.

I can't wait for Rockpick's post that he uses 3 in 1

 

You need to baby the engine for the first 5,000 miles or so and break it in gently with a good quality 5w20

 

The new Mustangs Cobra, and Corvettes use the Synthetics oils. Ive been told Synth suspends particulates longer and they are trapped by the filter more efficiently. I use Mobile 1 in my Eclipse turbo, and will use it on my F150 once purchased!

thanks fo rthe feedback. I think I will go with the Mobil 1 5w -30.
I know it works. I do not know about the synthetic.
And I will do it myself. Too many horror stories, too expensive a truck.

 

Oh, No, not the infamous oil question again??? I use Mobil 1 0-20W. 7,500 miles new!
