from the article:
"It’s been a misconception for years that engine oil should be changed every 3000 miles, even though most auto manufacturers now recommend oil changes at 5,000, 7,000, or even 10,000 mile intervals under normal driving conditions"
Most people are severe service and dont realize it, so more frequent changes are still a good idea to get the crud out.

The Chrysler oil monitoring system described at the end of the article is sounds pretty impressive. I wonder how well it really works and when it will be available on retail vehicles? Sounds more advanced than other systems.

Well, consider the source: Greencar.com-environmental propaganda.
Such as: 3000 miles OCI are a hold over from the days of non-detergent single grade oils. Whew, that must be going back around 50 years or so. Or, California only recycles 60% of used motor oil.
Hmm, 60% isn't all that bad considering the current demographics in the Golden state.
I wonder who is dumping the other 40%?

The system described is Daimler not Chrysler. It does sound like a good system if it works. Even better, if it works and if it could be retrofitted to existing vehicles!

Until a few months ago they were the same company. This tech has been around for a while.

Whad'they mean "foul the taste"? I think it would make it taste pretty good. And given how good oil smells, I just have to think it would add a nice flavor to water.

I think this is the 2nd time I've seen you post this. I really need to see where you're coming from. It's not something like pregnancy or death. To think that your OCI decays from 7500 miles to 3000 miles with ONE act or ONE condition that's seen SOME of the time is way too one dimensional in view.
Most service is not severe in my view. Some are surely more ideal ..but to think that the 3k/3m myth is valid for more people than it is not ..is just a myth.

ok, maybe I should have worded it like this:
"Most people are severe service and dont realize it, so the people who are severe service (99% short trips, oil never up to temps, etc...)should stick with more frequent changes, with used oil analysis to verify if they can extend further"

20 dollar UOA vs the 20 dollar cost of an oil change, cheaper if you watch for specials, seem to make the point moot.
Screw the test, change the oil, be happy.

Even with "severe" service, 3000 miles is too often if the oil is decent. I change my Group II 10w30 in my 2.7 liter 4 cyl crew cab Toyota every 4000 miles. It is in service for mostly short stop and start deliveries and messenger type service, with 50% of that off road and 30% with 400 to 900 lb loads. at 152000 km (about 90,000 miles, this what I got back today.

But where are you getting your survey data from? Now I'd say that we're surely getting a whole lot of people who are engaging in less driving due to moving from soccer parents to empty nesters ..but most of them aren't retired and none of them routinely engage in true "short trip" usage (some surely do). They still commute and they still go shopping and they still do all sorts of things ..just less of it. That's why you'll see a 3-6k OCI that's actually a 6 month OCI. Nothing severe about it outside of the time component. I can commute 40 miles a day and only rack up 5k in 6 months if that's all I use the vehicle for (wife's car might be more sensible for grocery getting or whatever).
