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

My Toyota manual is pretty boring. Every 5000 miles change the oil,
replace the filter, and rotate the tires. I cheat on the latter since I
have a separate set of studs so they get rotated twice a year,
Thanksgiving weekend and whenever it thaws out.

I did notice from my log that this year was the latest I've went back to
summer tires. Global warming, dontcha know.

A little light reading for deniers.
