All cars, regardless of newer or older models, must change engine oil every 3000 miles. Because of fuel additives and the elimination of lead from gasoline, you no longer have to get spark plugs replaced. When you turn the key, and you hear a click, that's how you know the battery needs recharging or replacing. Automobile radiators are heat exchangers to keep the engine cool by circulating an engine coolant through the engine block. Tire pressure decreases by one pound for every 10 degrees drop in temperature. When the Check Engine Light comes on your car dash, it means the engine is too old and needs to be replaced. By replacing your car's brake pads every 15,000 miles, your car's braking system will run perfectly forever. Answers False. It would be best if you always used the manufacturer's recommended grade of oil. False.
