LONGEVITY TIPS
It is far easier to start a properly tuned engine with a used battery than it is to start an untuned engine with a new battery. In other words, an untuned engine will defeat a new, strong battery. Essentially, a tuned engine is more important than a strong battery if you could only have one. An easy start actually depends collectively upon the battery strength, the condition and timing of the ignition system (spark plugs, ignition coil, and spark plug wires), the fuel/air mixture, the volatility of the fuel, and the viscosity of the engine oil. Many of these items are addressed in a tune-up. Remember that an easy start reduces engine wear.
