Does 93 octane improve performance?
Does 93 octane improve performance? Premium gas must be, by law, at or above 91 percent, although you do also see 93 percent octane ultra-premium at many stations. Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or […]

What happens if your rotors are too thin?
What happens if your rotors are too thin? When a rotor is too thin, it overheats and warps, leading to an annoying vibration or pedal pulsation. When rotors were thicker, they could take the wear from the brake pads, be machined and still have enough metal left to dissipate the heat. Which of the following […]
