Better wear protection
Excellent fuel economy
Outstanding extreme-temperature performance.


Conventional lubricants are refined from crude oil. Contaminating elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium are inherent to crude oil and cannot be completely removed through the refining process.

Synthetic lubricants, on the other hand, are chemically engineered to form pure lubricants.

Synthetic lubricants contain no contaminants or molecules that don't serve a designed purpose.

In short, synthetics' versatility and pure, uniform molecular structure impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can't touch.


  • World's first API-qualified synthetic motor oil

  • Leader in synthetic lubricant technology

  • The only 25,000-mile oil

The introduction of the world's first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts.

AMSOIL has remained steadfast in its commitment to quality and precision lubricant engineering, leading the charge over the past four decades with many industry firsts.

Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and has followed the AMSOIL lead with introductions of synthetic motor oils of their own.

Accept no substitutes – AMSOIL is "The First in Synthetics®".

Why Now?

  • Automakers are moving up to synthetics

  • Helps vehicles last longer

  • Saves time & money

Modern engine technology is placing more burden on motor oils. Vehicle manufacturers are under tremendous pressure to provide fuel-efficient vehicles that produce fewer emissions than their predecessors.

AMSOIL synthetic lubricants deliver the robust film strength, extreme-temperature protection and maximum fuel efficiency automakers are looking for.

AMSOIL synthetic lubricants help vehicles last longer

AMSOIL synthetic motor oils help engines run at peak efficiency. Their pure, uniform molecular structure results in maximum friction reduction and outstanding wear protection. Lubricated components move more freely and remain closer to like-new condition, longer.

AMSOIL synthetic lubricants save time and money

AMSOIL synthetic lubricants deliver outstanding protection and extended service life. Fewer oil changes to perform, less oil to buy and reduced overall maintenance costs.


Using AMSOIL synthetic lubricants can help the environment

Consider the savings on the environment if, for example, the 243 million cars (excluding trucks, buses and taxis) in the United States were equipped with AMSOIL Signature Series Synthetic Motor Oil

If each vehicle has an oil capacity of five quarts, accumulates 15,000 miles annually and has the oil drained every 5,000 miles, practicing extended drain intervals with AMSOIL Signature Series would reduce the amount of oil used in the U.S. annually by over 2.4 billion quarts.
