Our Top 5 Best Synthetic Motor Oil Guide Summary:

Top 5 Best Synthetic Motor Oil Guide Summary

What is the best synthetic motor oil?

Motor oil or engine oil is designed to lubricate the internal parts of the engine. It forms a layer around metal components so moving parts can operate smoothly. Oil protects these parts against rust and also against wear and tear.

But what many people don’t know is that motor oil is also responsible for cooling the internal parts of the motor. The process of combustion produces extremely high temperatures and demands a motor oil that will lubricate, protect, and cool the motor as it operates continuously in the harshest driving conditions.

Through the years, technology made it possible to manufacture more efficient and more powerful 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 since the dawn of the motorized car/pickup. 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 means less damage. By reducing friction, the engine parts won’t wear out as easily. There’s less damage, less breakage and therefore, fewer replacements or servicing 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

The unique chemical makeup of synthetic oil means it performs differently than other oil. If you put synthetic oil into your vehicle, you’ll see the following benefits:

  • 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

Check the owner’s manual of your vehicle. If you can’t find the owner’s manual on an older car, pop open the hood and check the engine oil cap. It is recommended to follow the manufacturer’s recommended type of oil for every servicing.

What to look for when shopping for the ideal motor oil

Don’t let your engine blow up because you didn’t use quality oil!

If you’re staring at oil containers, unsure of which ones are worth the buy, look for these features:

  • Excellent viscosity. This helps the engine run smoother in cold climates or extremely hot temperatures.
  • High lubricating properties. This will decrease friction to allow the engine to run smoothly and lower fuel consumption.
  • Oil can contain some chemical additives that assist in looking after the engine. Additives help to break down residue so your engine stays clean and functions well.

Now that you know what to look out for, browse through these synthetic oils below and look for the one that most impresses and fulfills your vehicle’s requirements.
