When it comes to protecting your engine, not all motor oils are created equal. If you want superior wear protection, extended drain intervals, and peak performance, AMSOIL Signature Series 100% Synthetic Motor Oil stands in a league of its own. Designed for car enthusiasts, daily drivers, and fleet managers who demand the best, AMSOIL Signature Series outperforms the competition in every way.
Unmatched Engine Protection & Performance
Your engine faces extreme conditions every time you start it up. AMSOIL Signature Series is engineered with cutting-edge synthetic technology to minimize wear, reduce friction, and keep your engine running smoother for longer. It provides 75% more engine protection against wear and horsepower loss than industry standards require.
The Sequence IVA Engine Test, which must be passed to meet the API SN PLUS specification, simulates extended periods of stop-and-go driving. For 100 hours, the test engine cycles between 50 minutes of idling and 10 minutes of elevated rpm – conditions that encourage engine wear. The camshaft is then measured for wear in 84 locations and an average score is determined.
Longer Oil Change Intervals – Save Time & Money
Tired of frequent oil changes? AMSOIL Signature Series extends drain intervals up to 25,000 miles, 700 hours of operation, or one year (whichever comes first). This means fewer oil changes, saving you time and money while reducing waste. Whether you’re a high-mileage driver, a business with a fleet, or someone who wants to get the most out of every oil change, AMSOIL Signature Series delivers unmatched longevity.
In another test, an independent third-party lab compared AMSOIL synthetic motor oil head-to-head against a leading competitor in a 100,000-mile test. AMSOIL Signature Series provided far superior wear protection compared to the competition, keeping bearings looking like new after the 100,000-mile test.
Turbocharged Engine Protection
Today’s high-performance and turbocharged engines generate extreme heat, leading to oil breakdown and harmful deposits. AMSOIL Signature Series provides 72% better protection against turbo deposits than required by the GM dexos1® Gen 2 specification, ensuring peak turbo performance and reliability.
We challenged Signature Series to the GM Turbo Coking Test, which consists of 2,000 cycles of extreme heat soaks. An oil must limit the temperature change within the turbocharger to 13% or less to pass the test. Signature Series Motor Oil provides 72% better turbocharger protection than required by the GM dexos1 Gen 2 specification.
Cold Weather Starts? No Problem.
If you live in an area with harsh winters, you know how tough cold starts can be on your engine. AMSOIL Signature Series flows quickly at temperatures as low as -58°F, reducing startup wear and ensuring smooth performance even in the coldest conditions. Compared to competitors, it offers 38% better cold cranking viscosity, so your engine gets the protection it needs right from the start.
100% Protection Against LSPI – A Must for Modern Engines
Modern turbocharged and direct-injection engines are at risk for low-speed pre-ignition (LSPI), which can cause catastrophic engine damage. AMSOIL Signature Series provides 100% protection against LSPI, keeping your engine safe and running at its best.
Less Oil Consumption, Fewer Emissions
Thanks to its advanced synthetic formulation, AMSOIL Signature Series reduces oil burn-off and volatility, meaning you won’t have to top off your oil as often. This also leads to lower emissions, making it a better choice for both your engine and the environment.
Handles Extreme Heat & Heavy Loads
Whether you’re towing, hauling, or driving in scorching summer temperatures, AMSOIL Signature Series resists thermal breakdown better than conventional and synthetic blend oils. It maintains a stable viscosity and provides superior protection in high-stress conditions.
Signature Series keeps engines cleaner, longer. It is fortified with a heavy treatment of detergent additives, delivering 28% more acid-neutralizing powerLL than Mobil 1,* helping engines stay cleaner, longer.
