Top 5 Best Synthetic Motor Oil Guide Summary

Through the years, technology made it possible to manufacture more efficient oil products. All motor oils are extracted from crude oil. Crude oil comes from a mining process underground. New methods extracted more dynamic lubricants from crude oil, so engines using these oils work even better. Oils can be grouped in two types:

Conventional oils

Conventional oils are made from crude oil and have been used for years. The substance is less refined than synthetic oils. Conventional oils can lubricate an engine, but it tends to break down and leave deposits on engine components. The residue that conventional oils leaves can be sticky instead of creating a smooth surface.

Synthetic oils

Synthetic oils evolved along with technology. New methods enabled scientists to extract a more refined oil that’s more beneficial to engine functioning. The differences from conventional oils include:

  • Impurities are removed
  • There are less chance of residue forming
  • The chemicals that make up the oil are customized. They can then perform more in line with what an engine requires for optimal functioning

How oil helps your engine

Oil is used throughout your engine, and you need to make sure there’s enough of the substance so your engine’s parts can be well lubricated. This lubrication benefits your car as well as your budget in the following ways:

  • Oil creates smooth surfaces in moving parts. Less friction turns into less damage. Without resistance, the engine parts don’t wear out as easily; there’s less damage, less breakage and therefore, fewer replacements are necessary
  • Oil ensures that all parts easily move, which has an effect on how hard your engine has to work. If parts move effortlessly, less power is needed. You’ll use less fuel and have fewer emissions
  • Oil absorbs some of the heat created by friction in the engine. This allows parts to work more effectively and prevents heat damage. It helps keep your engine from overheating

Benefits of synthetic motor oils vs conventional oil

  • Your engine temperatures will be lower
  • Synthetic oil flows freely, even at low temperatures. This means it protects your vehicle’s parts even while your car is warming up
  • Synthetic oil doesn’t thin at high temperatures. When your car becomes extremely hot, your engine parts will still be well protected
