You can post whatever but I know what I see when I pass the gas stations every day. There is a dimes difference between grades here. In other words if regular is 2.55 then it goes $2.55 2.65 2.75.
Before the 1st regular was $2.39 which meant I was paying $2.59. I filled up day before yesterday at $2.89. That’s 30 cents in 15 days.
Where are you in CA? I know there are areas that are normally higher, but the tax is for the whole state, and the state average only had a few pennies bump up at the beginning of the year.
