Gas on your car?

i thought it really doesn't matter anymore?

if i remember right, it USE to be different back in the day, but now it's all the same(or close).

the cheapest one was the shittiest,
the middle one was the normal one,
and the highest one was the best one.

but now, there's good gas(??) in all of them, so...

the cheapest(87) is like the highest one back in the day,
then the middle one(9?) is a little better than the cheap one, but don't really need it,
and then the highest one is the best, but also there's no need for it.
