I use synthetic and change every 6k. Works out just fine for my car.

Yep. Synthetic oil. Lasts longer and not a petroleum product.

RE #2: I do the same....Mobile 1!

I used to work in the business on the technical side where we would test engines for hours on end without changing the oil. This involved MAJOR oil companies and OEMs....if you’re using synthetic you can go about 7500 miles...6000 for sure. Though synthetic is expensive and not for everyone due to engine break in, etc.

I do believe 3000 miles for most people is too much, especially in engines that are 10 years old or less.

I have been using Mobil1 synthetic oil for years and routinely go 15k miles between oil changes. But I do alot of highway commuting type driving. If you tow something or just drive a few miles and stop I'd go with the 3k recommendation and skip the synthetic oil. The owner's manual states it pretty clear. Dealer's make a lot of money from oil changes.
