Starting in the 1970s, countries began banning TEL due to its toxicity and its tendency to ruin the catalytic converters required for modern emission standards. Today, its use is almost entirely restricted to specialized aviation fuels (avgas). 2. Tokyo Electron Limited (TEL): A Semiconductor Giant
In the world of technology, TEL refers to Tokyo Electron Limited , a Japanese multinational and the world’s fourth-largest manufacturer of semiconductor production equipment as of 2025.
By raising the octane rating, TEL allowed engines to run at higher compression ratios, boosting power and fuel efficiency. It became the global standard for decades, especially during WWII, where it enabled high-performance aviation engines.
