+1 ...would never consider putting 93 in a car that didn't require it

People purchase premium clothing, premium coffee, premium foods, premium wines/spirits, premium handbags, premium fragrances, premium vehicles, premium anything and everything... but where they decide to save a few pennies is at the pump for the premium vehicle they purchased which takes them to their office/job which provides them with the funds for all the other premium goods in their life. yeah, makes sense.

Agreed and I believe that back to back tests do not provide accurate results because the ECU has not had ample time to adapt for the difference in fuel.

I use Shell Vpower in all my vehicles since Sunoco 94 was discontinued about a decade ago.

Is 91 in CA same as 93 elsewhere?

I've never seen 93 here. Just 87,89,91 and sometimes the 100 octane.

It's CA state law that 91 is the maximum octane approved for sale for street vehicles. It is part of the California-only reformulated gasoline regulations, CaRFG3. Here in the northeast we have 93 octane premium fuels.

no, it's not.

and yore likely to cause more problems putting premium in a car that is designed for regular. more buildup, less fuel mileage. big waste of money that gains you no performance.

We have 100/101 octane here but only a handful of stations carry it in the state and if you do not have a tune for it with supporting hardware it will create more harm than good. 95 is the max most stock off the shelf cars can run without damage.

I'm actually curious to see if a car that uses regular would benefit from premium of there's a rod knock happening in the motor.

I'm thinking it's a myth but I've heard it on more than one occasion.

gas is not going to fix the bearings.

If the 91 in CA is not the same then which cars require 93?

There's no way that a bunch of exotics and sports car that are sold in CA are stuck using the wrong octane...
