I am not understanding this. If the level is up into the twists of the dip stick it is overfilled.

When I bought my used ‘15 last year, the next day I checked the oil after sitting overnight. It was up over the first twist - in ,y opinion seriously overfilled.

I drained the oil per instructions - first removing the filter then I let it drain for an hour. I measured what came out which was 7.5 quarts. I then added 5 quarts - started it - and let it sit for an hour then slowly kept adding until I got it to the top of the hash marks. Took another 3/4 quart for a total of 5 3/4.

The last oil change was done at the dealer. They obviously rush it and don’t let it drain properly - then just add the 6 quarts and call it good. Obviously they didn’t get the last 1.5 quarts out.

Yes - I do my own oils changes now - I’m too OCD to let this stuff happen.

I personally think it takes more than 1/2 hour of sitting to read correctly, and wanted to verify my own particular F150 dipstick level.
I did point out between the top hole and first twist, not past first twist. I drained and measured 6 quarts and it drained an hour or more. I added 6 quarts to a fully oil drained engine. Beyond those statements the oil level on my dipstick read as stated, factory stated 6 quart capacity. I guess my dipstick reads a bit high.
Or should I ignore the specifications and fill less than 6 quarts to match up the dipstick reading?
Made my observations and I know what I did and will use for reference from now on. KM

If it calls for 6 qts. put 6 qts. in it, it's easy to overthink this stuff. When it's running all of the oil is not in the oil pan anyway. Just put the number of qts. in it that it calls for and you'll be fine.

When I changed oil I never put in the full capacity before checking. If the capacity was 6 quarts I would put in 5 quarts. Then check the level and add the necessary amount. You're not going to get all the oil out of the engine when you drain it.

There is a problem doing that with "run stop" motors designed to keep oil in upper parts, it takes a while to drain into the pan. My 2.7 level keeps going up on the dipstick till after a 1/2 hour of sitting, checked more than once. 6 quarts in and now I'm sure of the level indicated (after sufficient time) is good enough for me.

You shouldn't check the oil level in any engine right after you pour oil into it. They all take time for it to drain down in the pan. If you pour 5 quarts in then go clean up your mess and put up your tools by the time you get back 15-20 minutes will easily go by.

For routine checks I prefer to check it after it has sat overnight.

That was exactly my point.

I have a routine most of my life for many things. One of them is I check my fluids after the truck has been sitting overnight.

When I did this when I first brought my truck home the oil level read above the first twist on the stick.

I changed the oil - added 5 quarts - then let it sit for 1 hour. Added a few ounces - let it sit for 1 hour - until I got it to read at the top of the hash marks.

Reading the manual is says to let the truck sit for 15 minutes before checking the oil. When I do that it reads 1/2 way on the hash marks. Overnight it reads at the top of the hash marks. Just right in my opinion.

I know I am overthinking this but that is the way I am. Reading all I could find on this with the 2.7L engine - basically you need to let the oil drain for 30 minutes. These shops are not going to wait for that - they get them in and out as fast as they can.

We each have out own way of doing things - I'm not saying that my way is right or anyone else's way is wrong. Just the way I do things.

My old 95 302 has a page with a picture in the owners manual regarding oil level reading after changing the oil. It basically gives an area above the hatch marks where the oil can read after changing and be fine not overfilled. Must be difficult for people to wrap their head around the fact that yes we put these hash marks where oil should read but it's okay if the oil is higher than that level. Very counterintuitive.
