The gas hasn't been changed because of fuel injection, it was mandated to be changed by the EPA for lower emissions. Then manufacturers changed their materials and technologies to best use the only gas that was for sale on a large scale. So a modern carbed engine will run just fine on today's oxygenated gas, but one from 30 years ago may have all kinds of problems. New or old though fuel injection has the ability to self adjust for all kinds of changes it runs into. The carb has some ability, but no where near what a bunch of sensors and a computer can do on the fly.
