I too use a bit of a hybrid system in my 2001 Chev Venture. I change the oil when it gets to about 20-30%. Usually 6000 Km or so.

I completely trust the OLM (oil life monitor). We've been wasting oil and resources for years. We now have the technology to tell us when the oil really needs changing. This is just one small way to reduce our consumption and since the mfg's are willing to warranty the vehicle you can bet they're not going to let it harm your ride.

I change mine in my 2000 F150 every 6000 to 8000. The other vehicles i own run about 10,000 between oil changes. I run my vehicles to at least 150,000 miles minimum and up to 300,000 miles. All were running when I sold them and none used oil. I seen one the other day and it has 500,000 mils on it. The car looks sad and does use a quart every 5000 miles but it still runs good. In the vehicles I own that tell you when to change the oil that' what I follow. I'm sure the manufacturer doesn't want me bowing motors that would make them look bad.

I've been changing mine on both vehs when the OLM gets down to around 10%. It's been working out to around 7K miles or so. I also use full synthetic, either Mobil 1 or Valvoline SynPower-whichever I can get the better price on...

even in the 70's, when oil/lube work moved from "Service Stations" that were your corner gas station with mechanics on staff, to the jiffy, hurry up and get outta here oil change drive thrus, the people that manufacture the MOTORS said 5000 to 7500 miles on average for oil change interval.
Now, the people that make the oil, the people that profit from you changing the oil twice as often as the maker says, they will tell you change it real often.
Look at the profit motive they have. You use twice the oil, they earn twice the profits, and if something goes awry with their lubricant, it was an engine problem.
Car rental companies, a place that depends on a reliable fleet, changes at 7500 intervals. When I serviced the trucks for NJ Bell Tel Co, it was at 5000 intervals. My own vehicle gets changed at least once per year, or about every 10K.
We have advanced in bearing manufacture technology. We have advanced in the lubricating properties of motor oil. We have progressed greatly in lowering the RPM an engine needs to maintain speed. Everyone EXCEPT the oil companies have advanced their specs.

The 3000 mile interval comes from back when oil had more paraffin and less detergent. Oil is engineered much better today, and so are the filters and engines. Follow engine manufacture's schedule, as most oil manufactures will advice you to do. Any sooner is a waste. Use a quality filter!!

I change my oil every 3,000 miles. It is on $25.00 for a lube, oil, filter, rotate tires, inspect stuff. For the TV that tows the trailer, it is only insured for 7,500 miles per year. So if I switch to changing the oil every 6,00 miles I only save 25 bucks a year. Dinner with DW costs more than that.
For the first time in my life, one of my vehicles has exceeded 200k miles. Normally they have died around 190k miles.

I too beleive in 3 to 4000 miles. Always have, those expert engineers that recommend that extended interval are the very same experts that designed the intake on my Dodge that is cast aluminum open bottom and then put a stamped steel pan to seal it up. Do you see a problem? Did you ever hear of designed failure. How about lubed for life ball joints. I take care of my own maintenance I figure its cheap insurance. By the way our 2 vehicles are a 94 Ford van with 220,000 and a 97 Dodge with 192,000 they are both running like new.
I'm not saying I'm right but I'll stick with what works.

I would like to add, changing oil intervals is a personal preference, its your vehicle do what you think is right and you are comfortable with.

A professor of Ag Engineering named Jim Frisbee at University of Missouri said, "I figure that the oil company wants to sell oil and that the car company wants to sell cars, so I change my oil somewhere between the oil-company's recommendation and the car company's recommendation.
AND
The company I used to work for saw 5000 miles as a nice, round, easy-to-remember number that fit nearly perfectly into Dr. Frisbee's rule.
