Not farm machine stuff
Just way I check the truck.
Check cold 1st
Start.
Min or 2
Let it sit 4or 5
Check again.
Note difference in noggin per ruff idea of what is in system still versus on the stick that aint gone back to pan.
In the upper half of cross hatch on stick good
Low bottom on stick.
Add 4 or 5 oz check
Maybe add again depending


Everyone got different idiocencrancies on how they do it.


When I change oil
Run to thermostat opens .
Shut down
Drain oil
Rock vehicle with my body weight on plug side.
More oil drained.
Start engine for a slow count to 6
Shutdown dont give engine light or rough run a chance
At least another 1/2 to 3/4 quart drains out from oil syetem.
pouring out of drain plug again briefly
Filter comes off empty

New filter , drain plug install.
Add oil
5qt sump 99% of the time will take the real world full system 6 qts.

Been doing it for decades.
No ill effects on any vehicle I have had.
Have had some extremely high mileage vehicles.
One example
89 ranger with 280k on the odometer and the worm gear on the speedometer cable broke for the last 3 yrs I had it.

What I do.
YMMV.
