If you go 7500 miles, use a good synthetic like Mobile1, Pennzoil Platinum, Castrol Syntec. Watch Advance/Autozone/O'Reilly auto parts stores for oil deals. Advance will run 5 quarts of Mobile1 full synthetic with Purolator PureOne for 25 bucks. Can't beat that. You might want to ask the dealership what they recommend. I would not run a standard dinosaur oil 7500 miles. Synthetics have really come down in price.
If you have a WalMart, check them out. They have 5 quart jugs in my area for the above oils for 23-25 bucks. I make sure to get a good oil filter as well, Mobile1, Purolator, and WIX are good. Do not use a FRAM. While Motorcraft is generally used for Fords, their oils can be used in any vehicle. Their oil analysis show that it is a pretty good oil that holds up well. Walmart sells their 5qt synthetic blend jug for 12 bucks.
I've changed my oil change indicator to 5k miles as my wife does a lot of stop-go city driving. once we are out of warranty, I'll take an oil sample and send it off to Blackstone Labs and see how far we can stretch the oil change intervals.
Before I got the outlander, I was a die hard 3k mile interval guy. Now that I finally have a nicer car, I've read up on oils. They've gotten quite a bit better.
