2004 F-150 Oil Weight Show Join Date: Apr 2005 Location: Maryland Posts: 31 Likes: 0 Received 0 Likes on 0 Posts 2004 F-150 Oil Weight
I just did my first oil change on my truck over the holiday weekend. The owners manual called for 5W-20; however, my dad seemed to feel that it was too light and thought it sounded like the grade I would use in the winter time. I figured the engineers at Ford probably know better than either of us about which oil works best in the engine; but, I did want to see what you all thought. Go with what the owners manual says or go with something a little heavier like 10W-30? Thanks in advance...

It is spec for these trucks.It will give you better gas mileage and is safe for warranty reasons. Just dont let it get low on level. Also I believe the 5/20 is part synthetic.

I wouldn't recommend (or use) anything else for warranty purposes, except maybe a full synthetic if it's available. Just my opinion though.... if it's out of warranty, do as you see fit. IMHO, regular oil and filter changes are more important than the weight of oil used anyways. -Joe

If it does not burn it off too quick, stick with it, if it burns it quick go with a heavier weight like 10-30.

Interested in hearing what you guys have to say on this topic. I was reading on another site about running oil other than 5w-20 in these trucks to cut down on VCT ticking and/or dieseling sounds from the 5.4L at low rpms. Apparently, there was a service bulletin years ago stating that owners may elect to use motorcraft 10w-40. I had read folks also used 5w-30 as well. I've run nothing but 5w-20, but found this interesting all the same.

However, I only have about 3000 miles on my rig, so I may not be the best source of information on the VCT issue.

Join Date: Sep 2012 Location: St. Charles, MO Posts: 112 Likes: 0 Received 1 Like on 1 Post I guess I'm that guy...Mobil1 Full Syn 10w-40 with Motorcraft filter. I was starting to get the VCT shakes with 5w-20 and 5w-30. YMMV, but for me the heavier weight oil raised the oil pressure enough to get the VCT system up and running again. EDIT: This is probably what you're referring to. Definitely never made it to an official TSB, and not sure if one was ever put out for the 04-08s specifically.
For me, the shaking and real loud noise only happened at operating temp under light throttle. I could confirm with my Gryphon tuner that the variable timing was going wacky. For my next oil change, I'll probably go with 5w40, just so it's not as thick through the winter (cold starts). Last edited by mletchworth; 07-28-2014 at 02:32 PM.

I'm a little over 104000. I'm going to have it torn down and looked at eventually. It makes me nervous but power seems fine.
