It doesn't take a trained mechanic to change the oil in a car. But to get the task done right and prevent future damage, you need to know what kind of oil to use. This can be found in your car's user manual, but knowing how to read oil ratings is important.
Viscosity
Oil is rated by its viscosity, or ability to flow. Oil viscosity is labeled using a number system, such as 10W-40 or 20-50.
Rating
The first number in the oil rating (10 in 10W-40) designates how well the oil will flow in low temperatures, while the second number (40 in 10W-40) rates the oil for high temperatures.
Temperature
According to the Society of Automotive Engineers, the temperature range at which oil should remain is zero to 210 degrees Fahrenheit.
Winter Oil
In cold climates and seasons, use oil with a lower rating, such as 10W-40. Additionally, the W on the oil rating designates its usefulness in winter. In low temperature, oil will thicken and have difficulty flowing through your engine.
Summer Oil
In summer or in hotter climates, a higher rating would be preferable, such as 20-50 oil. In higher temperatures, the oil can thin out and possibly become too thin to prevent friction.
