You can go a lot longer!
Have you done a used oil analysis to confirm that?

I was told buy 2 different delerships that oil needs to be done every 3000 and needs be proven in order to keep the lifetime powertrain warrenty but thinking about it I really think that any way they can figure out to void it there gonna try.
^^Shady business practices. They can't dictate oil change interval like that. You only have to go by the book unless They provide the oil changes at different intervals for free. Magnusson-Moss warranty act covers stuff like this. If you ever get any flak from them, mention the MM act and give them your attorneys card and they will stfu quick.
Most modern oils, Especially Full synthetics like Amsoil, Mobil1 Extended, etc. Can go much further than 5K intervals. Auto MFG's are pushing longer intervals to lower their pollution generation levels as a way to lower overall gubment dictated standards for emission/pollution generation.
UOA's of many of Amsoils full syns (using their Ea series filters) show that OCI's can be extended past 10-15K. I have a customer w/ an 05 Mustang running the 7500 series 5w20, non full syn oil w/ an Ea series filter to 9-10K miles and his UOA's are coming back showing the oil is still in good condition to continue using.
Regardless of all of that, unless you plan on keeping your vehicle forever and running it into the ground, even Good modern dino oil w/ a 5K OCI using good filtration should allow an engine to last a good long time w/ little chance of an oil related failure.
Personally, I run the best products, change my oil once a year or 10K miles (yeah, no commuting here), have good OUA's in the past and peace of mind doing so.
