Today's engines are well designed to drive farther than the 3000 mile

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 - - - - - -

Not with modern engines that require nothing else before you replace the car
for other reasons.
