My dealer has forgotten to reset the oil change indicator once, it's no big deal. The oil change indicator goes by engine revolutions and not mileage. If you are changing oil at 3K you can make sure the oil change reset is done at next change.
As far as "sludge" in the coolant: The coolant didn't turn to sludge. GM puts a rust inhibitor in with the coolant and it settles at the bottom of the radiator. It is supposed to be there. You can have the coolant flushed out and this will get rid of the "sludge." Valvoline techs would not know this. Some guys chose to flush the coolant out because of the "sludge." This is not necessary. Change it out at the recommended intervals.
Your dealer most probably checked the coolant level and either added some or it was still full. As far as the dealer only adding 5 quarts, all they did was short change you a quart. It did no damage.

GTOJudge,
Your inisights here are good, but allow me to raise a question.
You said:
"Your dealer most probably checked the coolant level and either added some or it was still full. As far as the dealer only adding 5 quarts, all they did was short change you a quart. It did no damage."
Really, it did no damage? How are you so sure of this. It may not have done damage noticeable to the naked eye or ear, but I have spent my career working in a mechanical related field. I am inclined to think opposite for the following reasons:
1. Less oil equals more friction, which induces greater heat.
2. Proper oil levels are vital in terms of engine longetivity.
3. Also most engine wear occurs within the first few minutes of turning it over, if this is a city car, that could be a frequent event, maybe every mile for three thousand miles, equaling 3000 times!
This is just a small sample of points which allow me to object to your rapid conclusion posted at an earlier date.
