About Premium Gasoline in Mount Vernon
Premium unleaded is $$4.48 per gallon in Mount Vernon, New York right now. The premium over regular reflects real refining cost differences. For qualified vehicles, the performance difference is genuine — for others, it is wasted money.
TOP TIER certification means the fuel exceeds EPA minimum detergency standards. Studies suggest TOP TIER fuels meaningfully reduce engine deposits vs. minimum-standard fuels. Most major brands (Shell, Chevron, BP, Costco) are TOP TIER certified.
Mixing grades is generally fine in practice — your engine's knock sensors will adjust timing accordingly. If your vehicle requires premium and you add some regular, no immediate damage occurs. Consistently running below the required octane in a performance engine is not recommended long-term.
