So the major difference between your numbers and the ones I cited, is that EROI is just "energy in versus energy out" and it does not change favorably if you do carbon capture or use renewables or whatnot.

Whereas if you compare CO2 emissions, you can do these things and in theory get down to zero emissions from production and refining of gasoline.

you are right -- EROI and emissions are different. If you add in things like carbon capture, emissions go down but energy-in goes up. Would it make sense to extract and refine gasoline with net-0 emissions if it took more energy than you get out in gasoline? _maybe_, but I don't think its a clear yes!
