Your engine is the heart of your vehicle; the more you care for its maintenance, the better your car will perform. There are numerous ways to ensure that the car engine functions at its best. Visit your mechanic for an oil change after 3000 miles or once every three months. This will prevent your engine from forming metal-eating sludge and allow its machinery to function smoothly. It is also imperative to abstain from racing your engine during start-up. Moreover, if you do not want your engine to wear out, avoid accelerating at high speeds, especially during extreme weather. Lastly, do not forget to clean its air filter every 15,000 miles.
