The modern automobile is safer, cleaner, more efficient, and more technologically advanced than anything that came before it. Yet those improvements have come at a cost. For many owners, mechanics, and independent repair shops, that cost is repairability.
So for US folks out there, that equates to roughly 47MPG
Diesel is great and all, but currently in the Midwest, specifically the Chicago area, GasBuddy shows "regular" 87 octane hovering around $4-4.10gal and diesel at ~$5.50/gal.
That 2017 Honda Civic achieved roughly 30mpg city/40hwy (depending on trim, engine, trans, etc) call it 35mpg averaged.
So if 35mpg costs you $4, and 47mpg costs you $5.5, then gas costs $0.114/mile and diesel costs $0.117/mile.
Now, technically speaking, diesel emits more CO2 than gasoline per gallon burned, however, because gasoline isn't as efficient per mile, diesel had a very slight advantage of being about 5% lower CO2 emissions per mile; however, it emits more NOx per mile.
5L = 1.32gal
100Km = 62 miles

All in all, they're pretty tied, IMO.
