As to when it happened it varies by area. In MA it's been a couple years
like most major metros.

Subject: MTBE out and ethanol in

I wonder when this changeover occurred. The sludge that I found in my three
year-old tank seemed to be composed of rust and a whitish, waxy substance. I
had speculated that it was a Techroline treatment that had loosend up this
muck but mayhap it was ethanol-blended gasoline.
