Ford F-150 oil consumption

We hear complaints about the Ford EcoBoost engine all the time – especially in rainy or humid conditions. But a new lawsuit, filed on January 6, specifically pertains to the 5.0-liter, V-8 engine and excessive oil consumption. It affects 2018 to 2020 models.

As reported by CarComplaints.com, the owners filing suit allege that the excessive oil consumption causes the engine to fail at any speed (i.e. potentially while at highway speed) and that Ford is concealing this from consumers.

This lawsuit is still in the early, early stages, so we aren’t likely to see any movement on this soon. But let’s point out a few key points.

Specifically, the lawsuit alleges:

  • F-150 engines have a defect that allow oil into the combustion chambers, which is then burned off and reduces the amount of oil in the engine.
  • There is a decrease in fuel efficiency.
  • Carbon deposits form inside the engine and damage the ignition and emissions components.
  • Piston and piston ring assemblies also have defects, which cause the engine oil to enter the combustion chamber.
  • The engine oil isn’t separated from the combustion cycle and is instead burned and consumed.

Additionally, the lawsuit refers to several technical service bulletins (TSBs), one of which instructed technicians to replace the engine block if the excessive oil consumption persisted. But the lawsuit alleges at some point technicians were told to stop replacing the engine and just add more oil “as necessary.”

The bottom line F-150 oil consumption lawsuit

The original class action suit has more than 84-pages associated with it, so clearly there’s a lot more being alleged than we can summarize in five bullet points and 300 words. So, we’ll keep an eye on any developments and let you know if anything comes of the lawsuit.

If you have an 2018-2020 F-150, have you noticed any oil consumption issues?

    “We hear complaints about the Ford EcoBoost engine all the time – especially in rainy or humid conditions.”
    Is this still true, to this day, Jan 2021?

    I have a 2020 XLT V8 5.0L that came off the line 08/2020. At approximately 3500 miles I decided to check the oil for the first time and to my surprise noticed I was 2 quarts low. Two days later I had TSB-2365 performed (which includes a free oil change) for engine oil consumption. I’ve been obsessively checking the oil every few days ever since, and so far it seems ok but only driven about 700 miles. Time will tell if this TSB helped or not.

    Brand new 2021 5.0 F-150. 2700 miles I get low oil warning. Check oil and barely wet on end of dipstick??? WTH?

    I have a 2018 f150 xlt sport 5.0 and I was 5 quarts low, so I took it in to the dealer and they did a pressure test and said nothing was wrong with it!! They then told me if it happens again to bring it back in and they would bring in a engineer from Ford to look at it, I had the tsb’s in hand they kinda looked at me weird and said my truck didn’t show any signs of the problems on the 4 tsb’s I had.

    I bought a 2018 F150 with the 5.0 litre in March of 2019. After the second oil change, I checked the oil after running up 6000 miles and was about a quart and a half low (quarter inch below the low mark). At that point I caught on to the oil consumption issue and starting checking my oil every other gas fill up. I am now at 30000 miles and can definitely confirm that my 5.0 litre consumes oil. The highest consumption so far was about a quart over 3000 miles (so within what Ford considers “normal”). I was certainly not enthusiastic about having the possibility of having the long block replaced – I would much rather top up occasionally. On a positive note, oil consumption seems to be decreasing as the overall mileage goes up, which is cause for optimism. I still find it disappointing considering that the atmospheric V6 in my 2017 Explorer hardly burned any oil at all (no need for a top up between oil changes). Hopefully the 5.0’s piston rings will end up seating properly on that spray-on bore lining (if that’s the problem).

    Been having consumption problem since first oil change. Dealer just changed dipstick and tbs?? Lead tech said 4 quarts low shouldn’t hurt engine.??? Wtf???

    1. David Simmons November 9, 2021

      Me too. Same problem with my 2018 Ford F 150 with the Coyote V-8. Still consumes oil even after all TSB’s completed.

    2. Dean Bullinger November 18, 2021

      Same problem @ 30 000 miles 4 quarts low every oil change lead tech said shouldn’t effect engine. Sure sounds and runs different from new. Wtf

      I have a 2018 Ford F-150 xlt and before it’s time to change the oil and filter I have to add 4 more quarts.

    Just finding out about this regarding my F150 that I purchased used with 31,000 miles on it. Changed the oil at 35,000 and have already had to add almost a quart in 3,600 miles! Sadly, I traded off a 1996 XLT with 210,000+ miles and it never used this much oil. Will continue to monitor the situation and hope Ford is forced to man-up.

  8. James N Glaze February 10, 2022

    I have a 2018 F150 that is doing the same thing . Oil consumption. The first couple times I changed oil I thought it was just the engine breaking in cycle. But the last 3 times I have had the oil changed it has been very low or not even showing on the dip stick. i have never had any vehicle I owned do this! They pay these engineers triple digits pay checks and they can’t even develop an engine that doesn’t consume gallons of OIL ! This is ridiculous !

    Interesting comments. My 2013 F150 used no oil. My 2020 is another story. It’s uses oil. The capacity is around 8.75 per my shop. I see why it is so large. I’m using a quart about every 2,000 miles. I’m pissed. Glad to hear of class action suit. The statement that it is not excessive unless you use more than a quart in a 1000 miles is BS. THIS IS MY FOURTH 5.0 engine from Ford. My first oil user.

    My 2019 F-150 Coyote V-8 has used at least 2 quarts between oil changes averaging about 4700 miles. I’ve documented it since my first oil change at 39,000 miles at every oil change. Discovered from another dealer that Ford has extended the warranty to 60,000 miles even though it isn’t mentioned in the book. My dealer service reps “feigned?”ignorance when I told them about the unannounced extended warranty and the TSB (resetting ECM computer and new oil stick).

    The dealer finally consented at 58,500 mile oil change to do an oil consumption test after 2 1/4 Quarts consumption in 4700 miles. Ford says more than 1 quart in 3000 miles is excessive. I’m curious what they will do after oil test proves excessive oil consumption.

    Really disappointed with these newer fords.

    My 2019 F-150 is at 55000 miles and now the engine stuffers and oil light comes on. I checked oil and it’s down about a quart of oil

  13. Robert Drawbaugh October 24, 2022

    2019 F150 I purchased used from a dealer. First oil change it was a quart low. Second oil change it was almost 2 quarts low. I paid 50K for a vehicle that uses 2 quarts of oil between oil changes. This should be a crime!

    I have a 2018 Platinum F-150 and I she. Had engine noise since day one!!! Tonight I discovered my F-150 almost completely dry of oil!!! I am religious about my maintenance and service on my truck. Ford, something has to give!!! Your customer service is lousy and you don’t make quality vehicles like before! Being a Ford girl, that’s hard to accept!!!
