What makes new cars have less need for oil change?

[luvya]

Besides marketing, what's the reason that new cars can run substantially longer before an oil change?

Old cars can run substantially longer too - at least 5k miles on regular dino oil, and 10k won't be of any detriment if the oil is synthetic. Everyone bought into the oil companies' claims that oil should be changed every 3k miles.

The oil companies pwned me. 🙁

There's a big difference between the first oil change and oil changes thereafter.

I don't give a sh!t what any manufacturer says, there's no way in fsck I'd ever leave break-in oil in the engine for more than a couple thousand miles.

As for regular intervals.. it depends on your driving habbits, environment, etc.

Currently, the 3,000 mile oil change is mostly marketing.. but it didn't used to be that way.

Both engine and lubrication technology has come a long way in the last few decades. That is the reason for the increase. Engines burn cleaner, oils are more pure and have better specifications..

Your car companies research has shown that that's detrimental? I assume you've spent more than all the others combined researching this? 😛

It goes against common sense, so until I see some evidence that shows it isn't detrimental, I'm not just going to believe them because they say so. 😛

The ammount of wear particles inside the engine during breakin is thousands of times greater than during normal operation after breakin. Most oil filters are only designed to last ~6,000 miles before they become saturated under normal operating conditions.

A bypassing oil filter is a worthless oil filter. Unfiltered oil is second worst only to no oil at all.. lol
