Today's engines are well designed to drive farther than the 3000 mile
change, especially if using synthetic blends. Though, you didn't provide
vehicle info, I'll guess it as within 10 years old and the 5000 mile
change will not hurt it, thus, the 3000 surely won't hurt either. You're
just spending more money. It is recommended to follow the manufacturers
guide in the manual.
I get the maintenance light every 5000 miles and change the oil then. I
was on vacation so I'm over this time but it will live.
It's a different animal but when a company I worked for went to Detroit
60 diesels they also started to do oil analysis. The protocol had been
12000 miles for oil and filters but it was lengthened to 20000. The shop
manager said they still weren't seeing significant degradation at 20000
but they needed to set some figure.

Some airport FBO's can send a sample to a lab or you can get a kit from
some places:

I've heard/read similar stories about engine mileage being extended to
10,000 or more without issues. Many experts also note that the old 3000
mileage change habit is wasting money.
Not nearly as muchas going 10000 when you SHOULD have changed it at
3 - and you end up replacing or rebuilding an engine -- - -
Gasoline and oil are the 2 cheapest things you will put into your
engine - - - - - -
How do you figure that.
Gas is the most expensive part of the cost of running a car by far,
like 10x every other part except maybe depreciation if you insist on
buying them new and you don't drive much. That is based in detailed
records when I was claiming car mileage on my taxes. Gas is 10-12
cents a mile at 20 MPG. A lot of cars won't even average that and your
gas is much more than $2.50 a gallon. It is more than that here most
of the time to.
Oil changes are probably the biggest maintenance expense, particularly
if you take it to someone every 3000 miles (1 to 1.25 cents a mile)
The only other thing close is tires and that will depend on how fancy
the tires are.
