You put in enough to raise the level so it is between the two marks on the dipstick.Some years before when I did not use my own oil at this mechanic and/or oil change shop the level always came up to maximum mark . I am uncertain as to whether they put in more than 6 quarts.
If the engine needs 5 quarts, he put in 5 quarts, that would be good enough for me, provided he was competent enough to reinstall the drain plug.I was working at a shop chatting with a tech as he finished up an oil change. He poured 5 quarts in, put the cap on and shut the hood. I asked, aren't you going to check the oil? He replied, "You just watched me pour 5 quarts in!"
Couldn't argue with that!
Then you messed up. The 4.9 i6 is the one that takes 6 qts, the 5.0 302 takes 5.I, also, have a problem with his attitude in #9. Not checking the oil after a change is a liability to him.
Everywhere I look my 93 F150 holds 6 quarts. The first time I changed the oil I just dumped in 6 quarts and it was way over filled. I found out, by careful measurement, on the the next oil change my engine holds 5 quarts.
OP already stated that the oil was between min/max and that when he added oil it stayed where it was, therefore no leak. Y'all have some serious issues.On my mustangs and my dad's '98 4.2L, filling with the oil amount indicated in the manual will consistently put the dipstick dead center between Low and Full. I have to add a half quart to each if I want to bring the levels up to Full on a fresh fill.
However, that doesn't excuse the rude mechanic. It is his responsibility to look that the oil level is at least in range on the dipstick and there are no leaks. Beyond that, he is good.

Yep. No calculations involved just measurements. Dump oil in. Run engine a minute or two. Let sit for another five. Check oil. Check oil the next day same thing.Are you including the filter in your calculations?
