There are many different types of engine oils. Most oil companies offer engine oil that contain additives and other chemicals to improve engine function. Oil is an integral component of the engine. It reduces the friction that occurs between the engine's moving parts. If oil was not present, then heat resulting from friction would damage the engine. Engine oil ensures that the engine is running properly and can also prevent engine parts from corroding over time
Determine the minimum and maximum temperatures in your area. In particular, what are the minimum and maximum temperatures in the summer and in the winter. Temperature is one of the most important factors when choosing engine oil.
Check the car's manual to see if a specific engine oil is recommended. Most manuals will provide information on the best type of oil for that engine as well as which suits the different climates.
Decipher the numbers and different grades of engine oil. The engine oil grade contains two numbers with the letter "W" in the middle. The first number refers to the viscosity of the oil at low temperatures and the second number refers to the viscosity at high temperatures. The W indicates that the first number is for running in winter.
Choose engine oils that have low first numbers if your climate is frequently below freezing. The colder the temperature the thinner the oil needs to be to move around the engine. Very thick engine oil will not work well in cold temperatures, and you will have difficulty starting your vehicle. Very thin oil used for cold temperatures tends to be fully synthetic, which enhances the power and performance of the engine and is also excellent for cold starting. Synthetic oils are made of compounds derived from mineral oils.
Choose engine oil that has a higher first and second number if your climate is normally warm and does not get very cold in the winter. These oils provide good protection but are thicker as the climate is warm and there is no issue with cold starting the vehicle. Most engine oils for hot climates tend to be semi-synthetic. Semi-synthetic oils are blends of synthetic oils and mineral oils.
Add a cold weather fuel treatment to your fuel if you live in extremely cold climate. The additive helps to lubricate the engine and stop the oil from thickening in cold weather. These additives contain anti-gel agents to prevent fuel and oil from thickening.
