The government is the biggest joke around. People are to easily bought and a man's word don't mean anything there. A man's word don't mean much anymore anywhere due to the fact we are showed by our leadership that it's ok to lie and hide things. Seems everyone has an ulterior motive. That's why technologies to improve gas milage have been bought out and buried since the beginning of the internal combustion engine.

I find it unlikely that the number is 300g. Seems slightly stretched but I have no doubt the truth of the matter would be shocking to many. 100+ undoubtedly. Have issues getting to read afr with torque on my car. I assume I don't have proper sensors for it. But seems even most diesel only produce less than 1g per mile. Trying to find some definitive tests though. On vacation so hope to come back on and find someone else did it. But respectively would guess that lean burn mode increase is typically 20%+ efficiency gain. If no emissions don't Increase by a matching rate someone should crack that aftermarket tuning/modding and make millions screwing over our governments for their Idiocracy.

If you have a carburetor vehicle all you need is a wide band O2 meter and the proper tuning kit for your carb.

For those concerned about the thermal stress that an engine would have while running leaner, and those who eventually would feel quite uncomfortable due to the increase on NOx, supplemental water injection might be a good way to overcome those issues.

Not just the refinery, since that extra amount of fuel (and the imported petroleum) would still require hauling, which is also quite energy-expensive and polluting. Considering that tanker ships hauling oil from the Middle East and Venezuela are not so strictly emissions-controlled as road vehicles, and that one of the main complains about NOx is that it turns sea water more acidic, lean-burn doesn't seem so problematic at all.
