I'm a preventive maintenance nut (synthetic oil changes every 3,000 miles),
A ginormous waste of oil and money then, since that is not called for in your manual.
It's your money to waste as you see fit. That said, if you are following manufacturer's recommendations for intervals over 5-6K, or worse yet, letting an on-board "maintenance minder" con you into doing intervals of 9,10, or more, don't be surprised when you hit 80-100k , see a check engine light, and then hear some pretty ugly news from your mechanic. Modern engines are built to extraordinarily tight specs, run very thin oil, and use technology that was not common even a decade ago, like gas sealing rings and direct injection. As a result, engines are failing very early due to wear from extended interval oil changes. It's everything from worn cams, worn timing chains, guides and gears, rings, extreme oil consumption, and total failure, like a rod through the block. I have a good friend who works in an independent shop, and specializes in major engine repair and replacement. He is replacing at least one engine a week, and doing expensive internal repairs to other engines continuously. Like many in the field, he is well aware that the root cause of this is extended interval oil changes.
Now it's easy to respond to information like this with, "well, I guess he thinks he knows better that the manufacturer, eh?" Well, it's simple. When 90%+ of the failures engines you work on are seriously compromised, or have failed, well before they are a decade old and have less than 125K miles on them, AND have a documented history of extended oil changes, it's a little hard to reach other conclusions. Especially when the same shop has hundreds of customers who maintain their vehicles at 5K intervals, or less, and have no problems. Personally, I only buy used, and I will not touch a vehicle without a paper trail of regular oil changes in the 5k range. As for specific brands with issues, it really doesn't matter. My son runs a 2015 Ford F150 for an outfit that demands that that employees follow maintenance minders, to keep service costs lower. His 3.7 ecoboost just failed at 75k, needing $3k in cam repairs, others in the fleet are doing the same thing starting at roughly 70K miles. My buddy reports that one of the Chevy CUV motors regularly fails before 80k, following the company's onboard computer maintenance minder. The problem is so prevalent that dealers stock a kit with all the parts needed to replace the timing chain and other parts that prematurely failed. Subarus are another popular car when it comes to big issues, with many burning massive amounts of oil, until the change intervals are lowered to 4K, or so, then the car doesn't burn a drop. Doesn't matter if it's a $60k new Mercedes, or a $12 New Nissan Versa. You want to keep it for several hundred thousand miles? Changes the damn oil, frequently, and preferable with synthetic.
As to the OP's question, IF you are paying 1/2 of what a comparable CRV or RAV costs, it is probably worth it. We are on our third CRV. It gets mileage in the mid-20s and is reliable as an anvil. My son's girl had an escape. In a year of trying to keep that thing on the road, he spent more of his weekends wrenching on that POS than I did in eight years of CRV ownership. He called it the "Ford Excuse".
