THE EPA LAWS FOR ONE. I'm slightly younger compared to other guys on the forums however I know you can squeeze an instant 5mpg by removing your catalytic converter  and a few more by going back to leaded fuels.
*DISCLAIMER* Removal of a catalytic converter is illegal, and I'm 99% sure leaded gas is as well on public roads. Do not attempt to make your engine more gas efficient no matter how tempting it may be!
But hey I mean 25% efficiency engines are great because they make less pollution per volume.  Funny thing about this is you make more pollution to burn all the extra fuel needed to go the same distance. Cars actually used to get better mileage. I think the real question here ought to be: What exactly is the EPA fighting for here again? |
Younger, probably. Technically ignorant, definitely. This is not a personal attack on you, but rather the old wive's tale that pulling your catalytic converter off will yield magic powers. THat was true in 1974, when cat cons were first required, as us "old" guys know. But modern engines are designed with the emissions systems as integrated parts of the entire unit, and have a far less dramatic effect on performance and mileage. In fact, most vehicles will lose gas mileage by disabling the emissions control systems. Engines, including the emissions systems,are far moreefficient than they have ever been - just look at the HP / Gas mileage being pulled out of small 4 cyl motors, or the monster numbers from modern V-8s - these ain't your grandfather's engines...
