But, you'd better have some understanding of what keeps your auto ticking. Soap, water and wax only scratch the surface of auto ownership. Without some understanding, you might spend more time in the auto shop than on the road, and more money on repairs than you need to. The three best things you can do for your auto is to change the oil, service the cooling system and replace the filters. All three are outlined in the manual.
Motor oil is the lifeblood of the engine, which needs a transfusion on a regular basis.
A recent report for consumers implied that people change their oil too frequently. However, many OEMs recommend changing your oil every 3,000 miles, or three months, if you drive in severe conditions, which most people do. Check your owner's manual for specific recommendations on your auto. Like motor oil, antifreeze wears out and needs replacing. The general rule is to have the system flushed and fluid changed once every year, or at least once every two years.
