i've been using Arco gas with 10% Ethanol for more than 20 years, with NO GAS RELATED PROBLEMS. No need for gas additives with Ethanol. Over the years that included a 10-1 compression 69 Mach I Mustang, a 455 fire breathing 76 Pontiac Trans-Am down to our two 79 Ford half-ton work trucks with the 460 engine.
i would guestimate that Arco outsells chevron 8-10 times in the Lynnwood, Edmonds, Everett (Boeing country) area. The last time prices rose up, chevron was the only company to sell diesel for more than 5 bucks a gallon and the last company to bring regular gas prices below 4 bucks.
Companies that continue to rip-off the consumer and care nothing about the little people, will pay the price in the end. chevron and others give Big Business a bad name.
