I think its just oil shops keeping this myth alive to make some extra cash. Everyone heard to change your oil every 3,000 or 5,000 and they still "enforce" that myth by putting a little sticker on your windshield stating it should be changed again at that point.wikipedia said:
3000 Mile Oil Changes

I change the oil in my Beetles every 3000 miles or less, but that's because there's no oil filter! Plus, the owner's manual says so, even recommending 1500 in extreme cold or severe service. But those are 37 year old models. 
I am old enough to be allowed to forget some stuff, but I remember some time in distant past GM suggested 5000 mile changes on one of my vehicles. I believe it was either my 91 Lumina or 96 Grand Am that had 2 service intervals 3000 miles for severe driving or 6000 miles for more normal driving. I sort of got the impression everyone thought they were in the severe class and the 3000 idea stuck. In the Grand Am I always split the difference between the 2 and changed somewhere in between. That one never saw a drop of syn oil but I only drove it for 247,000 miles before giving it to my SIL for another years worth of driving. Who know how long it would have lasted with the other .

From what I've read, the suggested oil change was 1000 miles or so way back in the 20's. Kendall oil started selling '2000 mile' oil in the late 20's. It wasn't until the 50's (don't quote me) that that figure was boosted to 3000 miles. Even then, the flat head motors, low temp engines, and crappy gas, it was pushing the limit.
By the time multi grade oil came out, l953, 3000 mile changes started showing up.
3000-3500 mile oil changes were the norm for a long time. The oil companies like it, the filter makers liked it, and the service stations and garages liked it. The myth persists even these days in some circles.
Most 'experts' say 5000 miles is a reasonable interval for most folks.
With the better engines, better oils, and hotter running engines (burns off acids and water contamination), most engines have a 7,500 mile suggested change. (normal duty).
With oil life monitors, some are finding 10-12,000 miles (mostly highway use) before the gizmos tell you to change oil.
Pick a reasonable interval that you're comfortable with and stick to it.
Synthetic oil can go a lot longer that conventional oil, and some higher end filters can go that long too.

With the 12.5 to 1 compression ratio and the high pressure fuel injection of the 2.4 DI engine in the 2010 & 2011 Terrain & Nox fuel blow by is a real problem. Fuel blow by results in reduced oil viscosity and therefore reduced engine lubrication.dwendt44 said:From what I've read, the suggested oil change was 1000 miles or so way back in the 20's.

Changing the oil and filter every 3,000 or sooner will be the norm for me with this engine.
And as I have stated before someone else will own my Terrain before the warranty is up.
