I would use it too, but unfortunately they are screwing the California consumer by patenting essentially high-octane gas formulations that would meet California emissions requirements. So if you want to sell gas in California that meets the emissions requirements, pay up!

I use Chevron Supreme. It has the highest amount of Techron of any Chevron gas, and Techron is a fine additive. See my post on Fuel Injector cleaners.

Monthly, I add a can of Red line SI-2 as an adjunct cleaner.

 

i always use either shell (93 octane) or sunoco 94 octane. for some reason my car "feels" faster with 93 octane so ill be switching back to 93 forever.

 

As long as it's 93 octane (here in Louisiana) that's what goes in. But I make my routine trips to the same stations so it's not much different. Either Shell, Exxon, or Chevron here..

 

AMOCO GAS EVERY FILL UP

 

Shell 93 or Sunoco Ultra 94

 

Maybe I am the only one that feels that different fuel formulation feels different in cars. Anybody else?

Shell or 76 only for me; Chevron makes my car sounds and
feels lethargic. This goes the same for all the Honda cars I've owned.

Me too.

 

Chervron exclusively. I have heard good things about their additive Techroline and NSX owners also prefer Chevron in their cars.
In my old Landcruiser I could put anything that could pass for gasoline but in high performance engines I only use Chevron.
