Hold on though.
Something doesn’t make sense. I distinctly remember BEFORE unleaded gas came out they had two grades...ethyl and regular. Then when unleaded came out they had two grades...leaded and unleaded.
Ethyl was the stuff that made your car go fast. Regular was regular. Both had lead in them.
Then came unleaded gas. what the heck was regular gasoline back in the days before unleaded gasoline?
Something doesnt’ jive.
Just a lower octane blend, as always.
Historically, there have always been three pumps that ran off of two tanks at the station.
There was a high octane tank and a low octane tank.
The three pumps delivered high octane (premium), low octane (regular), or a mid-grade (a blend from the two tanks).
It is still basically done the same way.
Last Sunday, I bought “non-alcohol” gasoline from a “high-test” (premium) pump at a Kroger.
oops, i goofed.
it was like this:
regular or ethyl(both were leaded)
then...
regular or unleaded(regular was leaded)
then...
regular unleaded or hi-grade(both unleaded I think, but not sure)
then...
regular or premium or ethanol(three choices)
Old people could never figure out what to put in their car. The term “regular” was so over used it was nuts. Catalytic converters came out and people were burning them up right and left because they would drive to a small town with old pumps that didn’t specify “leaded or unleaded” If I remember right, Kerr McGee was the last station in my neighborhood to phase out ethyl...or maybe they just didn’t take the “ethyl” label off their pumps.
