Can you damage your car engine by changing the oil at every 3,000 miles?

The Ford dealer service advisors said that it could destroy the new engine by putting too much clean fluid in it. He advises every 10,000 miles between oil changes. I have a prepaid service plan. 2018 Ford Fusion

No you can change it every 10 miles if you want

Bull.

No, if anything it will make it last longer. Change it every 100 miles if you want to and can afford it.

I don't think so!
Synthetic oils will last that long and newer filters will also function that long.
But non-synthetic oils will not!
What needs to be verified is the oil and filter are capable of functioning that long!
To increase profit on the service agreement who ever is changing the oil might service it on the synthetic schedule while using non-synthetic items.
I had the opposite happen, a dealership was changing fluids (oils) on the non-synthetic schedule and using synthetic fluids.

Doesn't take a genius to read between-the-lines.

"Prepaid Service Plan"… And you think they're going to recommend anything that costs them a penny? Haha!

No but you can waste your time and money. I suspect the "dealer" is tired of you coming around all the time. The manufacturer recommends certain intervals for certain items for a reason. If you had read your owners manual, which you clearly haven't, the recommended interval for normal driving is 7500 miles. Your car will tell you when it's time

Of course not. That is the stupidest thing I have ever heard. But saying that, changing it every 3,000 miles it overkill and totally unnecessary. It is a waste of oil and money. If you use conventional oil change it every 5,000 miles. If you use synthetic change it every 7,500 miles.

No you can't damage it by changing the oil for the correct spec quality oil.
However why would you change the oil too often?
This is a total waste of money and bad for the planet.
You are better letting the car run its proper service intervals and getting proper servicing done.
3000 mile oil changes stopped being needed in the 1970's.
Quick lubee places push it as still needed as it generates business.
It is like a tune up.
No such thing on a modern car.

No, but it is a waste to change oil more often than the manufacturers recommended interval.
