Yep, I live in CA. Not much choice in gasoline containers. I fill with high octane. I keep track in the computer when the gasoline is rotated. Every 9 Keep track in the computer. High octane. No stabilizers used. Go early, early am as other drivers/smokers are quite dangerous when you have to refill some containers and carry them in your car.
Now, I belong to Costco and it opens at 6 am. Will now be cheaper and quicker.
