Keep It Lubed Up
Another must for keeping a car performing at its best is making sure to change the oil regularly. The engine oil helps lubricate the moving parts, ensuring that they don’t grind each other down. If you take two pieces of metal and quickly rub them together without any oil, they generate a lot of friction, which is significant for two reasons. The first is the parts start to wear down, and may eventually break, which is not good for the car as a whole. But the second reason this is significant is the heat produced by rubbing metal is a symptom of inefficiency. You want the engine’s energy input—the gas—to be converted to vehicle movement as efficiently as possible. If the energy input is being used to create vehicle movement and produce heat from friction, you aren’t getting the most from the gas. Changing the engine’s oil roughly every six months will help boost your car's efficiency, and will also help keep the engine healthy over the long haul.
