How full is too full?

Both my cars take 4 1/2 quarts of oil with a filter change. We take them to the Quicky lube for changes. They are overfull when I check them. I am assuming they put 5 quarts in when they change the oil. I see no problem with this so far but will it cause one later? Maybe weaken seals from the overfilling?
I tried 3 different places but all 3 do it even when I tell them it only holds 4 1/2 quarts with the filter change. 2 even said " Yes we know it only takes that amount" when I tell them. Even when I tell them, the next time I go, that I had told them before but it was still overfull when I checked it. I usually wait at least a day before I check just to be sure the level is correct. It never is more than an inch over the full line on the dipstick even 3 month after the change. So it is not something leaking into the oil.
Just want to know if it is a problem or not!!

Generally speaking I don't think a 1/2 quart of additional oil is going to be a problem, however, if your oil is 1 inch over the full mark that may be a concern! I personally have never seen an additional 1/2 quart of oil raise the level 1 inch over full. What kind of cars are we talking about here?

The cars are a 2001 Mitsubishi Galant V-6 and a 2003 Hyundia Elantra 4 cyl.
The Hyundia I just checked yesterday and it was about 1 inch above the full mark on the dipstick.
I am not sure how they do the oil in these places if they have a pump that reads out or gallon containers or what. Guess I need to pay more attention.

They should be able to fill it correctly if they are using the bulk oil. If you specify a type, they may use bottles and just let 'em drain in. Either way..it's BS that they are overfilling. You pay the same with bottles whether its a full qt or 1/2 bottle. Good places will put the oil in a bag and leave it in the car for you. Heck even Wally World does that.

If its too full, and your engine doesn't have a windage tray to prevent it, the crank can whip the oil into a froth and cause the pump to not give full pressure.

1" over full is too much.

Overfull is overfull! You are paying for a service, it is not being done correctly, make some noise!! Next time check the oil before you leave the parking lot, if it is too full find a manager, if the manager cant/wont o anything to correct the situation find a new shop. I am an electrician by trade, and have people take me to task because a light bulb did not last as long as they thought it should have, so I have no patience for someone who can do something about a customers complaint and wont. Just my 2 cents.

stepping off soap box now

Is it actually common practice to bag the old oil? I have never heard of such a thing. But on the rare occasions I don't DIY it, I do not go to chain oil change places. One being a VW specialist, the other is an independent shop that specializes in oil changes and seems to do a ton of business.

I think GunGuy45 was talking about putting the leftover 1/2 quart of fresh oil that is left in the bottle in a bag for the customer to take home?!? That way the customer is only getting 4 1/2 quarts of oil in a 4 1/2 quart engine and the left over 1/2 quart is returned to the customer for later use.
