NHTSA Complaint #11467072 — 2018 FORD F-150

I purchased a new Ford F150 with the 5.0 L V8 engine in April 2018. After the third oil change, I recognized what seemed to me to be an excessive oil consumption problem. After checking my dipstick every 300-400 miles, it appeared the consumption was about 1 quart of oil per 1000 miles. I reported this to the dealer and they applied TSB 18-2354 in April 2020. This included a reprogramming of the PCM and a new dip stick. Initially this TSB appeared to reduce some consumption. However, now in May 2022, it appears that my consumption is around 24 ounces per 1000 miles, which I feel is still excessive. My use of the vehicle is for local transportation and I have only towed 3 small trailers over the last 4 years. Therefore, the vehicle has always been operated well within the manufacturers specifications. I always use Ford motor oil 5W-20. I know there is a Class Action lawsuit against Ford over this issue. There are numerous complaints on the internet. I submit this complaint to document my problem before the 5 year engine warranty expires. I can also report the "decelleration rattle" that occurs when the engine is at low RPM, generally when cold. This rattle is not always present but I have seen it described in other complaints. To date, it does not seem to affect engine performance.
