I am still waiting for something from Ford that says it is acceptable for you to burn a quart of oil every 1-2k. Does not need to be notarized but would like to see 1 piece to back up that statement. Also don't need wise comments either. You made the statement that Ford says it, I would like to see it.
I'm not going to dig through the entire internet or try to find the specific reference in an industry mag/journal or elsewhere to which ford engine the statement applied to at what time, but the info has been posted for years about many manufacturers and what they have considered normal oil consumption. Please note that I said to ask Ford and they will probably say 1 qt every 1-2k was acceptable because they have said it in the past. It looks like jmr posted the specific detail on the 2018 explorer which states no more than 1 qt in 3k miles is acceptable. So my overgeneralized comment was off by 1K miles specific to the 2018 explorer, which is why I said check with ford for specifics on your engine.
Here is a reference from an Amsoil dealer specific to Ford ->
Top 40 Reasons for Motor oil Consumption For example, Ford Motor Company considers consumption as high as one quart of oil per 1,000 miles to be acceptable in a gasoline engine.
Ford 4.6L 2V oil consumption test -
Ford 4.6L oil consumption "Vehicles in normal service should get at least 1,450 km per liter (900 miles per quart) after 16,000 km (10,000 miles) of service. High speed driving, towing, high ambient temperature and other factors may result in greater oil use." This was from 2010, but if you want to dig into it, you can see if the current test still references the same info.
Ford 5.0L from late 80s/early 90s referencing 1 qt in 900 miles -

More recently, I believe there have been some concerns with the GT350 -
High Oil Consumption Again, sorry, but I am not going to dig into everything Ford has ever said about oil consumption and find all the info for you. If you want to, you are more than welcome to do your own research. You are also welcome to stick your head in the sand like an ostrich. I personally don't care which option you go with.
The bigger concern for those running extended OCIs is to regularly check your oil levels. If you happen to be the person whose engine consumes about a qt every 3k, you may not like what you see when 10k miles rolls around and you go for an oil change (assuming you don't have an issue before that).
Please also note that I wasn't personally saying 1 qt every 1, 2 or 3K miles was normal. I consider anything more than 1 qt every 5-6K to be excessive for normal driving, but I don't expect anyone to really give a **** what I think. Everyone should do their own research and decide what is best for them.
