Change Oil

Most car manufacturers advise car owners that they change engine oil once a year for a brand new car or when they reach 7,500 miles. Whichever comes first. That is for gasoline powered engines. But for diesel powered engines, the time or mileage is shorter, usually you are required to change oil every 300 miles or once every six months. All this recommendations are applicable in normal or ideal driving conditions. And unfortunately, normal ideal driving for most of us means, in actuality, severe service driving. Severe service driving, which we often think as ideal driving are the often short trips under 10 miles, city driving… most likely a stop and go traffic situation, driving in dusty roads and sustained highway driving in hot seasons.
