WIVES TALE
I'm not sure where you got that idea. I have a 2009 Ford Ranger manual in my lap and it still has the 3month/3000mile change interval. WITH synthetic blend.
In fact, we get a letter in the mail from Ford every three months to remind us that the service for our 2005 Ford Taurus is due. I usually take care of that myself, but they send the notice anyway.
Even the 2010 Dodge diesel my boss owns has a little sticker from Speedy Lube in the corner that goes by 3month/3000 miles...
Ford officially extends oil change interval to 7,500 miles

Ford has been studying the question of when to suggest oil changes, and they've hit upon
7,500 miles for 2007 and newer cars. Not only are modern oils better, modern engines are also better. You don't have carburetors metering poorly on winter mornings, tolerances are a lot tighter, and operating temperatures are typically a little hotter, helping to cook off the junk that accumulates in the oil. Some manufacturers use a sensor to monitor the health of the oil and light a service lamp when it calculates change is required. Ford contends that its customers prefer a set amount of miles between changes. The automaker also cites the environmental benefits that come from less waste oil, monetary savings, as well as extensive tests as positive aspects of the new recommendation. I'm convinced that the only reason to suggest changing the oil at 3,000 miles in a modern car is to sell more oil. Perhaps an air-cooled Porsche would stress dino juice more, and could sensibly require changes at 3K, but you can stretch to drain intervals that would make your father gasp and clutch his chest by running modern oils in your modern engine. Of course, your driving pattern has a lot to do with it, as well. If you're in town for short hops, you'll require a shorter drain interval than the guy running Mobil 1 for his highway commute and changing the oil at 25 kilomile intervals (raising my hand).
2011 Model Year Brings New Oils, Longer Change Intervals
October 20th, 2010 The first time you take your new car in for an oil change, beware: Many 2011 models don't use the same oil as the equivalent 2010 models--even if they look virtually identical otherwise. And accidentally refilling with another oil that costs less could end up costing you big; using a different oil could void your warranty. It's no doubt something that every mechanic is aware of, but if yours isn't used to working on newer cars, it might pay to provide a reminder. According to Automotive News, all 2011 General Motors vehicles are being filled with next-generation motor oils that promises both higher fuel-efficiency and lower wear. The new oils—called GF-5, SN, or Dexos1—are being phased in this month and officially replace GF-4 and SM motor oils. The new oils will allow longer oil-change intervals as well, thanks to engineering changes that have been made together with the new standard—which has been in the works since 2006—including larger oil pans, more aluminum in engines, and oil-life-monitoring systems, which calculate intervals with data from driving style and other conditions. Ford is now specifying oil-change intervals of up to 10,000 miles with the new oil, while GM is relying entirely on driving conditions and its oil-monitor system. Dexos1 is a proprietary GM oil that's tested to slightly different standards, though some oils already on the market—Pennzoil Platinum and Quaker State Ultimate Durability synthetics are two of them—fully comply with each of these standards. GF-5 is the designation used by the International Lubricant Standardization and Approval Committee (ILSAC), while SN is the latest in a long list of comparably-named designations from the American Petroleum Institute (API). According to the API, all oils with the SN designation also meet GF-5 standards. These newer oils can be used in older vehicles, though they're likely to be a bit more expensive at first. Look to still see plenty of SM oils on the shelf for a while, too. One sign of an SN oil is that most will likely carry a "resource conserving" stamp in packaging. Here are the API designations you're likely to find in shops, as well as a few you might find in a dusty corner: SM – Up until this month, the latest standard; better oxidation and deposit resistance; wear protection; and low-temp performance than the oils it replaced SL – For 2004 and older automotive engines SJ – For 2001 and older automotive engines SH, SG, and SF – Each of these is considered obsolete [Automotive News; API]
