Hello all, 2020 F150 5.0. I have been hearing a lot about excessive oil use in 18 and up 5.0 engines. I have 20000 km on my truck and have not noticed anything yet. Is this common on these trucks and is there a fix?

 

If you haven't seen any consumption issues I wouldn't worry about it. There is a TSB that updates the programming to reduce vacuum and apparently, reduce oil bypassing the rings and getting into the combustion chamber. They also give you an "updated" dipstick that increases the "safe" range from 1 quart to 2.

Some also believe that the PTWA liners takes longer for the piston rings to seat. Some believe that the 8.8 quart capacity it too much so excess is being sent through the PCV system.

My 18 used maybe 1-1.5 quarts every 5k during the first 40k miles. I just filled 60k and use maybe half a quart every 5k. Barely noticable.

I just drive and enjoy.

 

Your 2020 should have the design changes from the factory already to prevent it.

 

My only oil loss on my 20 5.0 is when drain plug fails. 20,000 miles and on 3rd one

 

Thanks all, I haven’t seen anything on mine yet but I have heard a lot of owners usualyy 2018 complaining about this.

 

I think the oil usage problem was primarily with the first generation of the plasma-coated cylinders. I believe that they sorted out the issues, and the oil consumption issue is a thing of the past. My step-son has a 2020 version that's been completely problem free.

 

The dealership told me to wait until 20k miles before checking into oil consumption issues, they said they wouldn't do anything about it until the 20k mark. My 2020 5.0 has used oil from day 1. I have had it to the Ford dealership for consumption tests, they did all of the TSB's and reprogramming, they changed my oil and had me come back in 3,000 miles and it used 1 quart, then they said they didn't register the report with ford and they had to do it again. it used 1 quart in the 3,000 miles but he said it was right at the line and ford says it has to use more than 1 quart. total bull****. I'm hoping it wears in like others have said...but I doubt it. I changed my oil at 35,000 miles and I added 1 quart at 3,000 miles and over half a quart at 5,000 miles. I'm up in the air about turning this back on when my lease is up in July because adding a quart of oil is cheaper than the new truck payments. I'll probably buy it and sell it in a couple of years.

 

my 2019 5.0 F150 Lariat burned a lot of oil from day one up till 113,000 when cats finally went bad. TSB was done around 15,000 miles and made zero difference. Traded it for my current 2020 2.7 Lariat

 

Our 2018 used oil from day one! Did all of the TSB’s, etc, no change in oil consumption. Now, just days before our 5yr/60,000 mile power train warranty expires, took the truck to the dealer for white smoke coming out of the exhaust which made it appear that we had a head gasket gone bad. They checked it out and determined that it was actually oil that was burning causing the smoke. They checked the oil and found that we were over 5 qts low! We have never seen that kind of oil consumption, especially in just 2200 miles when I had last added a qt.

We now have just days left to do the oil consumption test and have them check the level to see if we qualify for a new engine for this issue. One would think that with the previous oil consumption rate, that after driving 500 miles, we would see a definitive change in the oil level. Unfortunately, we see no change at all. We have never seen it use that first qt till around 2000-2500 miles since oil change and am beginning to wonder if it isn’t the Ford motor oil that has been wearing out in this engine much sooner than it should is really part of the issue.

 

I can’t believe that with that kind of usage you didn’t get a CEL/MIL for the cats. No way they can live with that much oil going through them.

 

Yeah, I almost fell out of my chair when they told me it was that low. I would have thought it would have shown something as well. I’m sure though, that Cat won’t last much longer with the amount of oil that’s gone through it in the past 53,000 plus miles.

 

I think, if the complaint gets written up before the end of the warranty it would be covered. Crazy that it started gulping oil like that! I just traded my 2020 in on a 2023 with 5.0, hopefully it's taken care of on the new ones like they say it is. They said the 2020's were supposed to be fixed, but mine sure wasn't. Good luck to you.

 

I had the same issue with my 2018.
Did a lot of research on the issue from other technical sources, on how the coating is applied to an Alum bore.
Found out the rate of application determines the 'Porosity' of the application result.
A high Porosity surface can hold to much oil such that the Ring Pak cannot scrap away enough.
With a low tension ring pak, they just slide over the excess oil like a tire hydro glides on excess water.
Independently, I decided to add an additive to the oil to fll in some of the porosity on the cylinder linings and it seemed to have worked based on the research. A trial worth trying without consequence.
Vehicle purchased as a CPO with 28k miles not knowing it had this issue.
At 59k miles the oil issue has all but stopped after the additive began to work.
Now at 75k miles, no oil passage of any measurable consequence and still use MC 5W20 Blend oil.
Maybe I am lucky but the cause looms awful large as to the cause and the results I got from the additive with a bonus of a very quiet engine at Idle.
Bottom line is the lining process at the factory seems to have gotten out of quality control and left go to long.
A dealer cannot do anything about this in shop. The engine is not re-buildable in shop due to the cylinder lining.
The bore size is larger as would be the piston and ring dimensions. This engine displacement is a bit larger than 5 L at 307 cu/ in.
Good luck.

 

Yes, that is what we have been told will happen, but we also seem to be having our feet held to that date as far as determining that it meets/doesn't meet the criteria for Ford to replace the engine due to this issue.

 

2018s just weren't well sorted out. An all new engine that was still called the Coyote 5.0. The only thing it had in common with previous engines is that it’s still built on the old Modular tooling.

Ford has updated aspects of the current 5.0 to pretty much stop the oil usage, but 2018s were the first year of an all new engine, something to think about for those looking at used 2018s.
