Todays gas stinks, back in the 70's it smelled wonderful. Almost like todays race gas.

I can't believe with no cats you don't get fumes in the cabin, I have cats and if I go WOT I smell the cats in the car. First time I thought they were burning out, but found out it is normal.

Remember when Shell introduced ā€œReformulated Gasā€ that’s about when the ā€œOMG that smells horribleā€happened.

Early 70’s yes, by 1975 unleaded was at nearly every fuel station in the USA. All gasoline on road vehicles from 1975+ where manufactured with a catalytic converter thus requiring unleaded fuel.
