Most cars here are on a 12 months oil change or every 15K km (10K miles) which ever comes first.
How can they justify changing 3 times more often? What is the purpose apart from making 3 times more money?
Is it a car company conspiracy to use up Americas oil?
Cheers,

...However I still have the oil and filter changed every 5K Km on our cars. I specify premium synthetic oil and have a small one-man show do the oil/filter change twice in a row and every third service I send the cars into a service centre for a full once-over.
With decent cars having them serviced regularly is cheap-as-chips insurance.
Also I only run 98RON premium fuel in them as well.

We discussed this once on NAM (North American Motoring ...a MINI Cooper Forum) and the Europeans could not believe how wasteful the Americans were when it came to changing oil so often.
With MINIs, which uses synthetic oil and the recommended oil change interval is 15K miles, most Americans on the board were changing their oil at half that interval while the Europeans were adhering to it.
Here in the US, when you get your oil changed, they put a sticker on your windshield telling you when you will "require" your next one ...and they usually suggest 3K miles later.
I believe, as you suggest, the purpose of the 3K oil change is to make more money. Most manufactures are recommending 7.5K miles between changes with dino-oil. My mechanic has torn down MINI engines with over 150K miles on them and found the insides clean and sludge free ...these were cars that abided by the 15K miles oil change regiment and used synthetic oil.
reelsmith's axiom: Its going to be used equipment when I sell it, so it may as well be used equipment when I buy it.

They only held 3 quarts and didn't have an oil filter.
I've changed the Mobil 1 10/30, oil and air filter every 15k miles in our Mazda 626 turbo 13 times so far, and it's still running like new and losing only 1 quart between changes at 200,000 miles.

Auto makers recommend 7500mi (or longer) intervals between oil changes, but the auto maintenance industry has the public believing their cars will self-destruct unless the oil is changed every 3000 miles. Oil-changing salons are a large, profitable business.
- 15k miles is with synthetic oils, like Mobile One, not fossil-based...(nt) - mkuller 13:28:04 07/01/09

You are very correct.
If the power supply waveform isn't pretty,neither is the sound in most cases.
