Yeah most* engines can fairly easily do 7500mi changes on good synthetic. Even my 30 year old Honda expects 7500mi changes from the factory.
*I say “most” because a lot of modern direct injected turbocharged engines (designed for efficiency) have issues with fuel washdown due to DI cold starts and high turbo bearing heat cooking the oil to death. Those actually do need 5000mi oil changes typically, especially since 0w20 and 0w16 has real low film strength to start with.
To be sure of any OCI do an oil analysis from a lab like Blackstone at the end of your extended interval to make sure it’s still in acceptable shape.

Yeah I’ll totally get on that.
