Synthetic Versus Conventional Motor Oil

It's true. Synthetic oil is superior to conventional oil in almost every way.

How is Synthetic and Conventional Oil Different?

Although you might know that synthetic oils outperform conventional oils, you might not understand why. The differences begin at the molecular level.

Chances are good that you've previously read or heard that synthetic oil is an upgrade over conventional oil.  But do you know why? And are you aware of all the benefits synthetic oil has to offer? It's true--synthetic oil is superior to conventional oil in almost every way. Here, we'll explain the science behind the superiority, and also add to the list of benefits that synthetics provide. Hopefully, this will help you make the right decision the next time you need to give your engine the oil replacement it requires to keep it working perfectly.

The Science Behind Synthetic Oils

Synthetics don’t contain the impurities and molecular irregularities inherent to conventional oils. Synthetics’ pure, uniform molecular structures impart properties that provide wear protection, extreme-temperature performance and fuel efficiency conventional lubricants just can’t touch – all of which helps you save money with vehicles that run better and last longer.

All oils, synthetic and conventional included, consist of molecular chains of hydrogen and carbon atoms, referred to as hydrocarbons.  But in petroleum crude oil, many contaminating elements exist in its complex mixture of hydrocarbons, including sulfur, nitrogen, oxygen and metal components such as nickel or vanadium.  These mixtures are then refined, resulting in a more concentrated end product.  However, the chemical composition of conventional motor oil can vary substantially and depends on the raw crude oil refining process. Instead of having to be refined, synthetic oils are manufactured and chemically engineered for a certain molecular composition with a tailored and uniform structure. The orderly and planned design of the molecular structures in synthetic oil results in an end-product that is far more stable than their refined petroleum counterparts.

The Benefits of Synthetics Oils

  • Protects against horsepower loss
  • Less frequent oil changes
  • Lower service costs
  • Longer lasting engine
  • Better engine performance
  • Better viscosity means better performance in extreme temperature conditions
  • Keeps engine cleaner
  • Improves fuel efficiency

Only a microscopic film of oil separates metal surfaces in your engine from touching and causing wear. AMSOIL synthetic motor oils form a more durable fluid film than conventional oils due to their resilient base oils. They reduce wear and help you maximize engine life.


AMSOIL synthetic motor oils are designed to reduce emissions, last longer and reduce fuel consumption – all features that help prevent pollution. They resist volatilization (burn-off) better than conventional oils, which cuts tailpipe emissions, while extended-drain AMSOIL synthetic oils generate less waste oil and packaging waste since motorists use less oil throughout the year.



AMSOIL guarantees the performance of its products, so you can be confident they perform as advertised.
Warranty Secure

You can also be confident that using AMSOIL synthetic lubricants or practicing extended drain intervals will not void your new vehicle or equipment manufacturer’s warranty.
