How to Choose the Best Motor Oil for Your Car
Drivers like to know that they have the best motor oil in their engines for maximum lubrication effect. All cars should have the best sealing and lubrication of the moving parts within their engines, otherwise it would just seize up after a few miles. Choosing the best motor oil for your car is a matter of choosing the right viscosity of oil for the right time of year.
1 - What Is Viscosity?
The viscosity level of a fluid relates to its thickness and resistance to flowing. 0° Fahrenheit is the level by which the ratings are set for oil. For example, if you buy 5W30 motor oil for your car, you have purchased an oil which can cope with temperatures of 5° Fahrenheit and the ‘W' which it precedes it represents Winter. If you buy 10W-40 you will be buying an oil which is thicker than that of the 10W-30. The second number on an oil label is the viscosity, the thickness. Thicker oil will seal better and give your engine a superior level of film coating over the inside of the engine parts that it comes into contact with.
2 - Summer and Winter
Motor oils are manufactured with the seasons in mind. In the summer your oil needs to be a little thicker so that it can thin out suitably to the heat of the engine and the overall atmosphere of summer weather. The oil you put in your car needs to be able to stay at an acceptable viscosity level at higher temperatures. During winter months the oil needs to be slightly thinner so that it can cope with lower temperatures. It needs to be able to flow around your engine upon starting. This is when a lower rated oil will be more suitable to your vehicle's engine.
3 - Synthetic or Real?
Synthetic motor oils have been proven to be more effective for use in car engines. They use advanced technology and are far superior to mineral oils. They are in the same price bracket and for a mere couple of dollars extra, you will be giving your engine superior quality care. Synthetic oils also last longer than mineral oil. Regular motor oil is said to offer a basic minimum level of protection and while they are cheaper, they end up costing you dearly in the long run.
4 - Choosing the Right Oil
Choose your motor oil based on the time of year and the climate you live in. Motor oils are designed to perform to their best throughout the seasons. In summer, choose a recommended motor oil for your particular vehicle. Have a look in the manual for your car and read the recommended viscosity suggestions for the time of year you change your oil. You may also require a higher mileage motor oil if your car has been around the clock a few times. Deciding factors should be time of year, temperature and age of vehicle. All synthetic oils have suitable additives which offer anti-corrosion and anti-friction agents. Read the directions on the back of the oil bottle to find out if it is the best motor oil type for your car.
