After reading all these comments, I am convinced.
I compared the price of 12 gallons of Arco regular - which I usually use and guys on the racing circuit swear by - plus a $10 bottle of Techron, with the rip-off Chevron station down the road and 12 gallons of their Supreme w/Techron.
I hate to say it, but the rip-off Chervron station was $5 cheaper.
So what to do? Find the cheapest Chevron station and occasionally fill up w/Supreme and have done with it.
