81000 miles. Got to rattling/knocking so took it in and Ford house offered to change oil as nothing was on stick. I was only in about 2000 miles from last change. Rattle went away, but they told me to come back at 1000 miles. I took it back in and it was quart low. No leaks apparent, nothing on drive way. They told me to bring it in after another 500 miles. He said if still low, might need motor.
Google took to me to numerous problems and other solutions that don't sound as bad- one, new dipstick?? And reprogram the pcm? Something about cam shaft throwing oil out and computer can stop that?
One guy even said get higher viscosity oil and even Ford is now saying to swap from 520 weight.
Anyone have any experience with this or advice??

Yes, I'm just now about 4,500 miles into my new/remanufactured engine on my 2020 5.0. I was luckily under extended warranty (replacement approved and completed at ~85,000 miles). This was after approximately $10,000 in warranty work where they replaced cylinder heads back in 2023 (that did NOT solve the problem). At that point, I was under original powertrain. It was a long saga with lots of trips to the dealership and consumption tests. I finally ran into some outstanding service advisors and service department supervisors willing to listen that made it easy in the end. Mine was consuming approximately a quart every 1,000 miles. Frustrating, but I really like this truck otherwise and I decided I was digging in until I got some resolution and figured I'd see how good the ESP was. Paid off in the end I guess? I wish you the best of luck - this was a known issue I believe for some 2018-2020 models.

As mentioned, it's a known issue with 18-20 5.0 in particular. Good luck

Thank y'all. And unfortunately my extended warranty played out on time. Always drove GMC and Chevys. But loved the ride in this one and it tows better.
Don't know whether to deal with it or trade

New motor to save a quart of oil every 1000 miles seems kind of extreme

Where is it burning it? Valves or cylinder walls?

I'd start using high viscosity oil and also add into the oil couple of bottles of LIQUI MOLY Oil Additive CeraTec 20002.

Dont know. From reading, the cam stretches further during deacceleration and pushes oil out exaust, therefore no leaks or drips. I am not much of mechanic, but that makes sense. Is that why they say they can reprogram computer to tell cam what to do?

The cam, to my knowledge, is entirely mechanically controlled by the timing chains. I have no idea what any programming could do to have an effect on oil consumption. Perhaps lowering oil pressure? I have no idea...

TSB 19-2365: https://static.nhtsa.gov/odi/tsbs/2019/MC-10169811-0001.pdf

"...may be due to high intake manifold vacuum during some deceleration fuel shut off (DFSO) events resulting in oil being pulled into the combustion chamber from the crankcase, valve guides, and positive crankcase ventilation (PCV). To correct the condition, follow the Service Procedure steps to reprogram the powertrain control module (PCM), install a new engine oil level indicator and change the engine oil and oil filter. The revised PCM calibration reduces engine vacuum during some DFSO events."

Also: https://lemonlawhelp.com/ford-f-150-trucks-oil-consumption/

Your engine has VCT, the computer is capable of telling the cam what to do. However, it may or may not be the valvetrain that's causing your issue.

In any case, I'd install a catch can to mitigate sending oil/oil vapors through the intake.

I wouldn't hesitate to run 5w30

Thanks again. The lemon article makes me just want to swap it and go back to Chevy/GMC which I always drove before this one.

Then you get lifter failure. They all have issues these days, just pick the truck you like and hope for the best.

From article, sounds like they will try several remedies which short of new engine are just guess work maybe?
I can check oil daily if i have to, even though pain in the butt. Just dont want to get off somewhere and it blow up on me.
If lifter is problem in GM, kinda leaves the Tundra, but they are syre proud of them and guzzle gas.

GM just issued a a massive recall on the 6.2 engines due to them dying early. 5.3s have issues with DOD and VVT killing lifters.

Toyota is having engine failure issues with their new turbo engines.

If you're worried and risk averse, pick the truck you like the best, and get a good extended warranty.

Yes sir.. Bought one on this and I thought it had expired, but its good until September. . Saved my butt!

I just realized I mistakenly wrote in my reply to OP (and have since edited) that mine was consuming a quart every 5,000 miles; it was a quart per 1,000!

Edit to add: If you are indeed still under ESP, just stay after them and don't relent. They know what they need to do, just a matter of forcing their hand. Also, I think shortage of parts and actual engine blocks hurt me on the first major repair attempt, hence why they just did a cylinder head replacement and basically a rebuild instead of full replacement.
