It is not wrong.
The phrase "ignorance is bliss" is what you are describing.
The vast majority of consumers are clueless. They don't check their oil levels, pay attention to what the dealership is doing or how much they are charging.
As evidenced by the OP's experience, consumers will allow dealers to destructively overfill their engine oil, then overcharge them for the unnecessary product.
They have "no problems" and are "quite happy" because they are blissfully unaware of the poor service they received and ignorant of the costs/consequences.
Do you know anyone who has had damage from "destructively overfilling with oil"?
Your assumption seems to be that dealerships do more wrong than right so no one can't trust or rely on any of them.
Millions of vehicles successfully serviced by dealers and running millions of miles indicate otherwise.
People don't know or care about vehicle maintenance like they used to for one reason - they don't have to because cars are so much better and reliable.
An example is the oil dilution issue in the CRV.. if the problem was as bad and destructive as some on here would have us believe then the roads and highways would be littered with dead CRV with blown or locked up engines.
One thing turbos don't like is poor oil quality on bearings that are turning 120,000 rpms.
Anyone reporting turbo problems?
21,000 miles on my CRV and it runs fine and no oil consumption or damage with a high of 38.7 mpg.
Blanket statements such as yours are neither accurate or helpful.
