Yes refill do vary from dry fill amount on most engines. I have even some engine list refill amounts and forget about the extra oil an installed oil filter needs. With that I take the oil capacity with a grain of salt as it is just a general guidance. I usually fill near capacity listed and check. Once on initial refill and at least couple times after few minutes ran in. Sometimes they are fine and other time I need to add/remove oil. It also important to how they are checking the oil level. Some engines the oil dipstick is screwed all the way in and others it just sitting on the threads. I usually check the owners manuals when in doubt.
The truest measure of society is the how it treats its elderly, its pets, and its prisoners.
