Ahh, OK, so not your dime, I can understand that. Even then, the newer OEM parts do address some of the issues, just not quite as well as something like the Melling pump would.

Again, I personally would just use a cheap synthetic 5w-20 and change every 4000 miles or so. It is what I am doing with my BIL truck.
I could understand the desire to use a name brand 5w-30 synthetic though, my brain still thinks that way some times, but regardless, I would lean toward shorter OCI instead of longer (or even recommended).
This is part of the reason I say use a cheap syn oil, regardless of which oil brand or weight is used, 4000 miles is about the limit on these things. the long timing chains, hydraulic adjusters, VCT solenoids, phasers, just a lot of stuff going on in these things that can be hard on oil.


Hey i appreciate the feedback, i've heard go with a shorter oci but wasn't sure how short. This helps, and makes total sense why you mention to use something cheap!


I would go shorter than any other engine you can think of that needs frequent oil changes, because these are one of the most likely engines to fail IMO.

No this engine is historically robust significantly more reliable than the industry average.

5.4 is not robust. They fail often and early. Take care of it. There is a reason why you cant find them used. You don't need a HV oil pump. Its nice but way over priced.. I would say the standard volume Melling pump is a million times better than the Ford. I have one sitting in my garage to swap over in my 4.6 when I do the timing chains.

You are just plain wrong with your opinion.

How do you know that the 40 weight oil did not cause your problem? It serms everyone is scared of 5w20 oils. Stick with what the manual says and drive that sucker for 200,000 miles👍 I was scared of it also until gaining valuable knowledge on this site. This is a fun hobby for me.

Well I think it's very unlikely that ANY weight oil caused this issue; 20 or 40. This failure is not common i would say but there are examples of this specific failure out there with the 3V. All the issues I experienced pre-failure were prior to me trying 40w and with 20w in the sump. Again though; the failure was going to happen regardless.

I normally have no issue running what is spec'd but from my reading/research the 30w works well in the 3V(or at least certainly doesn't hurt).

Here's my thread when I knew something was up:

Hate to say it since I own one, but agree with caprice; they're not as good as the 2V for sure. Seems hit and miss though; my brother has the 3V in his '07 F150 and it has been trouble free for 175K miles, pretty ugly maintenance records to.

I have always wondered what s the true likelihood of having the 5.4L problems? Is it 10% of the Fords? 5%? 1%? 0.1%?

Think of it like this everyone in Phoenix could have one and there would be enough to give one to everyone in Tucson. There view you and Caprice is representative of a fraction of a percentage getting caught up in the micro view when making an statement as the whole is far from wise.

I wouldn't disagree with you there Dave. I think my feeling is more so not that it's "unreliable" but just has some weak design points as compared to the 2V. Or I guess more complexity is another way to put it. But again, I know there's a ton of these motors and a bunch with high miles. Actually there's a gentleman on YT that claims to have 600K on his '09, original engine/trans.
