wtf...engine oil overfill - worried
Car at 60.4k (almost 5k since last oil change from maintenance history) - just bought it almost 2 months ago. This morning just did oil change, ATF and coolant drain & fill at a good reputation shop but first time for me.
I brought 5 quarts of Matic-S and 6 quarts of MObile 1, JUST in case needed for some reason.
Shop return 1 quart of Matic-S (expected) but used all 6 quarts of Mobile 1. I didn't think too much and left but came home and start worrying about overfill.
Engine cool, check dip stick, oil at high end, dense oil stops where the dip stick bends which is about 1/3 of inch above "H".....should I be freaking out and get it drain out half quart or is it ok to drive?
I am very concerned...please advise

1 quart overfill is ok and safe to drive?
Before I was told...do NOT ever overfill engine oil to avoid damaging engine
Can't believe these car shops...i left extra quart for "just in case" but not for heck of it. I'm pissed.

^^^ Hmmmm... I'm not so sure. Overfilling by a quart in some cars (not sure about ours tho) can cause the oil to foam by the rapidly spinning crankshaft. This froth can't be easily pumped by the oil pump, so you essentially can starve your engine of lubricant-- imagine the potential side effects. It's like sucking the froth from a coke thru a straw, it's hard to get any real liquid.
Another problem is that the piston skirts and crankshaft can splash oil into your combustion chamber, below the piston rings. This may at times cause you to get blue smoke from your exhaust.
It's likely nothing, as *****-ah-sore said, but I'm neurotic enough (and not a car expert per se) that I'd worry about it. By the way, keep your receipts, just in case something develops down the line.
One piece of unsolicited advice, get to know the shop foreman or service manager well, and ask for their off the record recommendation for the best mechanic(s) and insist, gently, that they be the ones to work on your car. I've done this and the ASE certified tech has, over the years, insisted that he'll be the only one touching my car. The service manager is cool with this b/c I befriended him also. The good part of this is that they don't treat me like a dumb blonde.
Good luck and I hope this helps.

Not sure if this engine eats abnormal amount of oil as I just got it and it is my first oil change on this car.
If it is ok to drive, I won't go back to the shop to drain it out. I hope I'm not putting it in danger.

If you're really not sure how to proceed, drain some of the oil yourself when the engine is cold. I have a Fumoto valve, makes the job easy and very clean.

Ca sits for 15mins then check, it was almost 1 inch over H.
I decided to get a siphon pump at Pepboys for $12. Could not pump out oil from where u pour oil so I pumped from dipstick, I took out about 1/2 quart. With engine cold, now it sits on H. I assume now it should be safe to drive, right?
