Who is going to check? When I had a diesel Super Duty I ran off-road fuel when ever I could. It was 85 cents cheaper than low sulfer diesel and it was better for the engine. Never had a problem and I think I heard my engine thank me.

If you are that concerned about no leaded gas add hardened valve seats. I ran unleaded in my 68 Nova 350 with no problems.

But then it won't have date coded/numbers matching seats!

Still illegal though.

Let me guess, you are one of those California tree huggers?

Nope

Rare Earth Metals..... Almost all new technologies (Semiconductors, phones, Batteries for these cars as well as everything else) currently rely on the mining / production of Rare Earth metals of which most currently comes from China. There are already limitations on it's availability. I think this alone will soon slow some of the technologies mass distribution until good recycling practices are developed for them... IMOP...

No, it isn’t. It is illegal only if the road tax isn’t collected on it before useage. I sold hundreds of gallons per year to XKE owners.

EPA Takes Final Step in Phaseout of Leaded Gasoline
[EPA press release - January 29, 1996]
EPA Administrator Carol M. Browner today took the last steps concluding a 25-year Agency effort to phase out lead from gasoline.
Browner signed a final rulemaking to eliminate requirements which became obsolete or unnecessary as a result of the ban, including certain recordkeeping and reporting requirements for gasoline refiners and importers. Also, motor vehicle manufacturers will no longer be required to place "unleaded fuel only" labels on the dashboard and on or around the fuel filler inlet area of each new motor vehicle. Deleting these provisions will decrease compliance costs for industry.
"The elimination of lead from gas is one of the great environmental achievements of all time," Browner said. "Thousands of tons of lead have been removed from the air, and blood levels of lead in our children are down 70 percent. This means that millions of children will be spared the painful consequences of lead poisoning, such as permanent nerve damage, anemia or mental retardation." The actions taken today, although procedural, mark the end of a quarter-of-a-century of work to keep Americans safe from exposure to lead from gas.
Adverse health effects from elevated levels of lead in blood range from behavior disorders and anemia to mental retardation and permanent nerve damage. Fetuses and children are especially susceptible to low doses of lead, often suffering central nervous system damage or slowed growth.
Lead has been blended with gasoline, primarily to boost octane levels, since the early 1920s. EPA began working to reduce lead emissions soon after its inception, issuing the first reduction standards in 1973, which called for a gradual phasedown of lead to one tenth of a gram per gallon by 1986. The average lead content in gasoline in 1973 was 2-3 grams per gallon or about 200,000 tons of lead a year. In 1975, passenger cars and light trucks were manufactured with a more elaborate emission control system which included a catalytic converter that required lead-free fuel. In 1995 leaded fuel accounted for only 0.6 percent of total gasoline sales and less than 2,000 tons of lead per year. Effective January 1, 1996, the Clean Air Act banned the sale of the small amount of leaded fuel that was still available in some parts of the country for use in on-road vehicles. EPA said fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines.
In addition to increasing the octane of gasoline, leaded gasoline also protected exhaust valve seats (in vehicles designed to operate on leaded gasoline) from excessive wear. Both of these objectives are now accomplished without the use of leaded gasoline. Owners of older vehicles with engines designed for leaded fuel may use an unleaded gasoline of comparable octane. For vehicles operating under higher loads, a lead substitute additive may be used, but owners should check with vehicle manufacturers as to which lead substitute additives are appropriate.
