Cut pork into large cubes, about 4" each and season with pork rub.
Turn Instant Pot onto sear and add oil. Brown pork in batches until browned (or in a pan).
Add water to the bottom of the Instant Pot and be sure to scrape all of the brown bits off (to avoid a burn notice). Add root beer and garlic.
Add pork and cook on high pressure for 45 minutes (according to your product manual). Natural release for 15 minutes.
Remove the pork from the Instant Pot and using two forks, shred the meat. Add 1/4 cup juices from the Instant Pot (discard remaining juices). Stir in BBQ sauce.
Serve on toasted rolls with coleslaw.
Leftover pulled pork can be stored in an airtight container in the fridge for up to 4 days.
