It is not rocket science check the oil on a weekly basis keep good service records,?
Why would I do that?
Our cars don't use oil between 13,000 changes. The car does keep the record and displays warning when you have 1000, or less miles till next change.
For those insisting, that it is "their money" and "harm can't be done".
The oils manufactured during may adult life had always special formulas to improve the service. On the side of detergents they have chemicals design to neutralize engine acids.
Since the oils are changed with design intervals and chemicals wear out, the new oil is coming with overdose of chemicals, who wear out to perfect balance about 1/2 of its designed life and then the engine acids take over. Adding a quart some time after that would be a good thing.
So if the oil is design to work for 6000 miles and you change it at 3000, you dump perfectly balanced oil and replace it with new having overdose of aggressive chemicals.
You are right >>> it is your money.

Oil changes at 3K for anything but a police cruiser, taxi, delivery truck, or something else that sits idling in traffic all day are a complete waste of money. Period.
Let's see, just from my experience...
1986 Cherokee (GM V6-60), replacement engine (original seized due to overheating) went 223,000 miles--5W-30 Super Tech (Wal-Mart) oil, ST filter, changed at 5-6K. Ran perfectly when scrapped.
1988 Festiva (1.3 Mazda), running perfectly at 195K--5W-30 ST--still going.
1994 Crown Vic P71 (4.6 SOHC), ex-taxi, oil changed at 4K in service (5W-30 NAPA, Purolator filters), now 6K--ProLine (Pep Boys) 5W-30, ProLine filter--355K, still going. Only internal engine work was valve guide seals (of course) around 130K.
1989 Dodge Diplomat AHB (318 4bbl), ex-taxi, same schedule as above except using 15W-40 in summer--somewhere >450K, still going. Head gaskets replaced due to overheating at ~430K.
1985 Dodge Shelby Charger (2.2 turbo, hot-running and very hard on oil), sold with 245K--NAPA 5W-30 and anything except a Fram filter at 5K. Internally untouched, original turbo.
1992 F-350 (7.3 diesel, dealer-installed turbo), sold with 366K--Tech2000 (Wal-Mart) 15W-40 and ST or Motorcraft filter at 7500, 5K if I towed heavy or plowed. Second IP, original (ATS) turbo.
1993 Chrysler Concorde (3.5 SOHC), sold with 250K--5W-30 (hi-mileage synthetic blend after 100K) & NAPA filters, changed at 7500. Internally untouched.
1988 Dodge Dakota (TBI 3.9 V6), 5W-30 winter/10W-40 summer, changed at 6K, still going with 300,000 miles. Internally untouched.

I think you need to provide us with a detailed list of everything there is to know about your vehicles and personal oil changing habits so the rest of us will quit making inaccurate statements that most of us feel apply to more than just one person.
The number one killer of an engine is the lack of proper maintenance including regular oil and filter changes, cool system services including belts and hoses. If you don't do the maintenance you engine will not last as long as it could have, period.
Your engine might last 500,000 miles only changing the oil and filter every 100,000 miles but I will guarantee you it would have lasted another 100,000 miles had you changed the oil and filter every 50,000 miles, that's not a tuffy to figure out. Like I had sad earlier I don't recall ever hearing or seeing an engine die a premature death due to having it's oil changed too often.
Here is the inside of the oil filler cap and rocker cover on my everyday driver that has just over 216,000 miles on it. The engine is a virgin and retains every factory installed gasket except for the thermostat and water pump gaskets.
The oil has been changed every 3000 miles since the car was new, it's spotless inside. Looks good to me for 216,000 miles.
Here's the same picture of our Jeeps oil filler cap and the inside of the rocker cover, doesn't look so good does it??? The previous owner changed the oil every 5000+ miles (just like the factory recommended) up until I bought it with only 112,000 miles on it. It now has 132,000 miles on it and uses a quart every 1000 miles, what a joke.
From the two pictures above I know how often I will change my oil.

You just confirmed my theory. Aggressive chemicals in new oils eat the engine clean . You might try to confirm that by drinking your coffee with addition of dish-washing liquid.
On the other tough, better not.
You are right, that after running the engine for 500,000 miles not too many owners care about making another 100k, so unnecessary oil changes will not make enough harm for average owner to notice.
That's what the oil company are bidding on.
Care to increase their multibilion dollars profits?
Anyone?

Same here, its the way Ive been doing it for the last 45 years on every vehicle Ive owned. My Father was an owner operater truck driver and he taught me at and early age that changing your Oil & Filter evey 3000 miles will make your engine last.

Kajtek1 said "why would I do that" about checking the oil level. Ever seen a cross threaded or loose pan plug, or a loose oil filter? Doesn't take long to lose 5 quarts of oil, and the results can be a ruined engine. I check my oil at least once a week. Motors are expensive

You missed the point wanderingjays.
Once oil level drops close to min mark, the car will display warning message on the cluster. That never happened.
When I bought the new truck 10 years ago I paid the dealer to do the service.
In 4 years I opened the hood 3 times.
Once because of curiosity, once because friend was curious and once to install brake controller. The truck is turning 10 years old soon. My son drives it now. He opens the hood even less often.
