What To Know When Buying Engine Oil

posted on 3/23/2021 2:19:16 PM
Engine oil is one of the most recognized automotive fluids among drivers and passengers alike. Engine oil has evolved over the years with the advancements made in car engines. Oil is the lifeblood of your engine and needs to be replaced routinely to maintain performance and protection. Here's some information on engine oil that can help you choose the best type for your vehicle.What To Know When Buying Engine Oil
 

What Is Engine Oil Made Of?

Motor oil is vital for our vehicles, but what exactly is it made from? A majority of motor oils are made from a thicker and heavier petroleum hydrocarbon derived from crude oil. This is infused with multiple additives that improve upon certain qualities. While all engine oils are made using the same base of refined petroleum or synthesized polymers, they vary on what type of oil they are.
 

Types of Engine Oil

  • Mineral Engine Oil: This oil is typically referred to as Conventional Engine Oil and is made from refining crude petroleum and removing impurities. These oils can contain traces of compounds such as sulfur or nitrogen.
  • Synthetic Engine Oil: Synthetic engine oil is usually created chemically in laboratories, but it can also come from refined petroleum. Synthetic oils are better for your vehicle because they are chemically designed to retain the best properties after refining.

What Do The Number on The Engine Oil Bottles Mean?

If you've bought oil before, then you've probably noticed the series of numbers and letters on the label, but do you know what they mean? You'll usually find on the outside of the bottle something like this: SAE 5W-20.
  • SAE: This stands for The Society of Automotive Engineers, which is the body that established the grading system for oil weight.
  • 5W: The number preceding the W is the viscosity that the oil will have at low temperates.
  • -20: The number after the dash represents the viscosity of the oil at normal operating temperatures.

Why Are These Numbers Important?

The weight of engine oil affects how your engine will use the oil and how protected it will be at different temperatures. Since engine oil keeps the other parts of your engine protected and lubricated, the type of oil depends on your manufacturer.
 

What Type of Engine Oil Should I Get?

The easiest way to know what type of motor oil your engine uses is by looking at your owner's manual. Your manufacturer will state which type of engine oil you should use for optimal performance and longevity in your car. If you can't find your owner's manual, it might be labeled on your oil cap in the engine bay.
