Came across this while looking at the NBC NO streaming video.
This guy teaches automotive and does not even know what octane is?
ahahah "for pinging". Actually it's per engine design and you should pump what your vehicle manual says per your engine. Super is used for higher compression vehicles. Only a few engines require Super or medium 90 octane.

NEW ORLEANS -- Does it matter where you purchase your gasoline, and does buying high-octane fuel give you better gas mileage?
With fuel prices rising almost daily, experts say it's important to separate the facts from the myths.
In her latest outing, WDSU NewsChannel 6 consumer reporter Stephanie Boswell found regular unleaded as high as $2.05 a gallon and as low as $1.99.
With such a variety of fuel prices to choose from, why do some consumers pay the higher price? Because some believe fuel at the big name gas stations is better.Story continues below ad
Randy Trailor teaches motor vehicle technology at Delgado Community College. He said whether you buy from Shell or Spur, the fuel at local gas stations comes from the same refinery.
"The only difference is some of the additives they're putting in the fuel," Trailor said. "It comes from the same hole in the ground at the refinery where it was processed."
What about the octane level? There's a widespread perception that the higher the octane level you put in the car, the better its performance. Trailor said that's a myth.
"All the octane rating is is an anti-knock additive that they rate it as taking away engine ping and a little rattling noise, and does it burn even enough," Trailor said.
Another interesting fact is that now that gasoline prices have reached the $2 mark, some stations are running out of the number two for their outdoor signs.
