I'm currently on E85 since my last oil change about 3k miles. Could you tell me where you sent the oil analysis? I'm thinking to get it done as well.
Also, is there any other factors that we are able to check to determine if this increased oil change interval is just a myth?

As long as your oil is E85 compatable , generally most SN or GF5 rated oils are you should be fine its always best to check in the manufacturers spec to confirm.
some cars generally FI depending on tune boost levels ect may get some fuel dilution with E85. or some people just like to be cautious especially if tracking or driving hard in adverse or hot conditions. If you oil ananysis comes back fine then you can likely run the normal oil change intervals.
However some people like to change more frequently even if not running e85, its just personal preference,, go off the oil analysis.
