I pay 4.35 - 4.55 for nice premium CA petrol (have to call it petrol at this price). It's worth it you see. It smells better because they put some special CA fragrance. It burns cleaner 'cause we have to satisfy the CA tree huggers association, and CA processed (at the border really), and super synthesized, hi-resolution bs filled petrol. That's why we pay more.
Despite all this, I still drive like gas is cheap because of the Z.
