Years that auto racing banned the leaded fuel

[theriusDR3]

Leaded petroleum fuel is the most hazardous fuel which can cause pollution and dangerous to human health. Here are the auto racing competitions that ban the leaded fuel according to year:
1. Formula 1 in 1992
2. NASCAR globally in 2007

Any additions?

Not from me, but I was reading up on Vanwall recently and there was a lot of work done when methanol (or maybe nitromethane) was banned in approx 1958.
