Where did you even find 95 octane? The highest I've seen in Las Vegas is 91 octane, and the highest I've ever seen was 94 octane at one gas station in Michigan.
95 octane won't make much difference for your car...just stick with the recommended octane for your vehicle. That's what Toyota has determined will produce optimum gas mileage, performance, etc., and any upgrade (like to 95 octane) will pretty much be a waste of money.
