How to select the best type of engine oil for your car

Many at times engine manufacturers suggest two viscosities or more of the motor oil to be used in the engine. Such could include 5W to 20 or even 5W-30 on basis of various factors like temperature. The core reason for such is that engines depending on the conditions of operation require various viscosity. Understanding of aspects like viscosity from scientists’ perspective would aid in selecting the best type of motor oil for your car.

Viscosity

This is the flow resistance of the fluid. In the world of motor engine viscosity is stated as XW-XX. The number before the W represents the flow of the oil at 0 degrees and the W stands for the condition winter. If the number is low, it’s an indication of motor oil which thickens lesser during cold weather. For instance, motor oil labelled 5W-30 would thicken lesser when it is cold compared to oil labelled 10 W-30. Therefore, a car which operates in cold climate would much benefit from motor oil with viscosity of between 0W and 5W.

The 2nd number represents the viscosity of the oil at temperatures of 212 degrees. Typically, the number shows resistance of the oil at hot temperatures to thinning. For instance, 10W-30 motor oil would thin out when temperatures are higher at a faster rate compared to 10W-40 oil.

While with viscosity of the oils in mind aids in choosing the best motor oil type for your car some vehicle companies such as BMW and Mercedenz-Benz only recommend synthetic types of motor oils. Note that if you begin running your car on a certain engine oil type like the conventional type be keen to stick to it.

The common types of motor engine oils you can choose from include:

Conventional oil

The oil type commonly used in bulk for many deals and also it’s the cheapest sold at any auto store. The oil mostly adheres to SAE and API standards though offer little in additive packages methods. Conventional oil types are ideal for persons change engine oil frequently and also go for shorter mileage.

Synthetic oil

Such oils are created for engines of high-tech. if such oils go through special stringent test and pass it simply implies the oils have longer-lasting, superior performance in any critical area raging from protection against deposits in the engine to viscosity index. Although excellent, these oil types cost 3 times higher than normal conventional oils.
