Using Synthetic Motor oil is the best for your engines.

AMSOIL Synthetic Motor Oils outperform conventional oils, but do you know why?​

The differences begin at the molecular level. Synthetics don’t contain the impurities and molecular irregularities that are common to conventional oils. A Synthetic oil’s pure, uniform molecular structure contains properties that provide outstanding wear protection, extreme-temperature performance and fuel efficiency that conventional lubricants can’t touch.  AMSOIL uses quality synthetic base stocks as a foundation for all its oils.  This gives it the finest foundation, with the best properties to start with.  Then they develop their performance properties using the highest quality additives in the right amounts to achieve their desired results.  All of these properties help you save money with vehicles that run better and last longer.  Learn more about the basics of motor oils here.

AMSOIL motor oil provides serious engine protection.

Engine Protection

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.

Hot Temperatures

5 TIMES CLEANER ENGINES IN HOTTER CONDITIONS

In order to keep on pace with the increasingly strict fuel economy standards, vehicle manufacturers are designing engines differently, causing them to run hotter than ever before. The average operating temperature is up to 235°F, and even higher under heavy loads. This heat can quickly break down the oil and cause oxidation, sludge and deposits.

Recent tests show AMSOIL keeps engines 81% cleaner* (5 times cleaner) than conventional oil by better resisting the formation of deposits. *Supported by TEOST 33C test (ASTM D6335)

Cold Temperatures

36% EASIER AND FASTER COLD STARTS

When the temperature drops, motor oils thicken and move slower, causing parts of your engine to remain unprotected for a short period of time. AMSOIL is more fluid at cold temperatures than the tested conventional oil, giving you 36% easier and faster cold starts*. This means that it can reach vital components faster, providing more immediate engine protection and reduced wear.

ENVIRONMENTAL CONSERVATION

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.

Turbo Protection

Turbo Protection

Turbochargers push more air into the engine’s combustion chamber, providing better fuel economy and performance, but also creating intense operation conditions. Deposits caused by high engine temperatures can lead to a host of problems. Pre-ignition and engine-knock, reduced fuel economy and power are frequently traced back to excessive deposits.

  • In gas engines AMSOIL Signature Series 5W-30 handles heat so well that it protects turbochargers 72 percent better than required by GM’s dexos1® Gen 2 specification.*
  • AMSOIL Heavy-Duty Synthetic Diesel Oil is built to withstand the punishment turbos dish out, protecting against deposit formation in extreme temperatures. AMSOIL Signature Series Max-Duty Synthetic Diesel Oil provides protection boosted to the max, delivering up to 60 percent better turbo cleanliness* and withstanding the extra demands you place on that turbo when pulling heavy loads or updating the tune for maximum horsepower.
