AMSOIL Signature Series 0W-40 Synthetic Engine Oil 3.78L (Gallon) AZF1G

Pablo Boye — Sat, 12 Jul 2025 06:27:05 +0000

AMSOIL was founded on innovation, beginning with the introduction of the world’s first qualified synthetic motor oil. By ignoring commonly accepted limitations and refusing to stop short of success, AMSOIL set a new benchmark for lubricant performance. These same principles continue to guide the product development, resulting in Signature Series Synthetic Motor Oil. Signature Series is not only the best oil AMSOIL have ever made, it’s also better than any competitor oil Amsoil have tested. Some may claim that Signature Series is over-engineered. Perfect. It’s not for everyone. It’s for those who want the absolute best engine protectionand it delivers.

Protects Against Engine Wear

Signature Series synthetic motor oil develops a strong fluid film that keeps metal surfaces separated. Its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. 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 precondition’s that encourage engine wear. The camshaft is then measured for wear in 84 locations, and an average score is determined.

AMSOIL used Signature Series 0W-20, the lightest viscosity in the line, to further increase the severity of the test. AMSOIL Signature Series Synthetic Motor Oil provided 75% more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.

Protects Pistons from Low-Speed Pre-Ignition

AMSOIL armed Signature Series with an advanced detergent system that protects against harmful deposits and low speed pre-ignition (LSPI). Most new engines feature gasoline direct injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies, when combined with a poorly formulated motor oil, promote LSPI and threaten engine operation. LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in Todays advanced engines and is much more destructive than typical pre-ignition. A properly formulated motor oil is critical for protecting your engine.

Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. Signature Series Synthetic Motor Oil achieved 100% protection against LSPI in the engine text required by the dexos1 Gen 2 specification – zero occurrences were recorded throughout five consecutive tests.

Protects Turbochargers

AMOIL’s unique synthetic formulation is inherently stable to resist oxidation and neutralise acids. Signature Series motor oil provides outstanding protection against deposits common to high-temperature engine environments. The tremendous heat and stress turbos create can cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether.

AMSOIL 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 limited the temperature increase to only 3.6%, protecting the turbocharger 72% better than required by the GM dexos1 Gen 2 specification.

Maximum Cleaning Power to Battle Sludge

AMSOIL Signature Series Synthetic Motor Oil has 50% more detergents to help keep oil passages clean and promote oil circulation. Engine failures due to sludge are often caused by a plugged oil pick-up tube screen the motor is effectively starved of oil. The Sequence VG Engine Test measures an oil’s ability to prevent sludge. During the test, a Ford* 4.6L engine is subjected to sludge-inducing conditions for 216 hours. The industry standard allows for 10% blockage before the motor oil fails the test. Signature Series produced a screen virtually free from sludge. Its detergent and dispersant additives are so effective, Signature Series provides 90% better protection against sludge.

Superior Wear Protection

An independent lab compared AMSOIL synthetic motor oil head-to-head against a leading competitor in a 100,000-mile test. AMSOIL provided far superior wear protection and kept bearings looking like new.

Preserves Horsepower

The extreme durability of Signature Series Motor Oil helps your engine run stronger, for longer. Amsoil installed Signature Series 5W-30 Synthetic Motor Oil in a Ford* F-150* with a new 3.5L EcoBoost* engine to test its ability to protect turbocharged direct-injection (TDGI) engines from torque and horsepower loss during extended drain intervals up to 25,000 miles (40,200 km). Power sweeps were done at the beginning and end of the test to evaluate horsepower and torque retention. As the graph shows, Signature Series helped maintain engine performance throughout the 100,000-mile (160,934 km) test.

Keeps Pistons Cleaner

AMSOIL formulated Signature Series with superior thermal durability that resists breakdown and keeps pistons clean. The Sequence IIIH Test uses the Chrysler* 3.6L Pentastar* engine to evaluate a motor oil’s ability to resist heat and keep pistons clean. The test is conducted with oil temperatures of 304F (151C), much hotter than normal operation, to accelerate oil thickening and deposits. A single-length 90-hour test didn’t even challenge Signature Series. Its viscosity was like that of new oil, and the pistons were still nearly spotless. To really test the oil, AMSOIL told the lab to reassemble the engine and run the test again using the same oil. Even after doubling the length of the industry-standard test, the oil limited oil thickening to well under the allowable threshold while delivering 40% cleaner pistons than required by the standard.

AMSOIL SEVERE GEAR is excellent for severe applications, such as towing, hauling, steep-hill driving, commercial use, plowing, racing, off-road use, rapid acceleration, frequent stop-and-go operation and high ambient temperatures. Higher horsepower, towing and hauling capabilities of modern vehicles make pickups, SUVs, vans and delivery/utility vehicles especially prone to severe service. Other severe-duty vehicles include light-, medium- and heavy-duty trucks; buses; heavy equipment; 4X4s; tow trucks; race cars; tractors; and motor homes.

AMSOIL Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid – Gallons (3.78liters)

Pablo Boye — Tue, 06 Aug 2024 04:47:22 +0000

AMSOIL Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid – ATF1G

Product Highlights

AMSOIL Signature Series Multi-Vehicle Synthetic ATF is engineered to outperform conventional automatic transmission fluids and exceed the performance requirements of most North American, European and Asian vehicles. This sophisticated formulation provides outstanding performance and protection in the severe operating conditions of today’s most advanced transmission designs.

Transmission Fluid Evacuation Service:

Transmissions in commercial vehicles, SUVs, trucks and vans – particularly those used for hauling or towing – are subjected to severe-service operation and increased heat. Elevated temperatures cause fluids to break down, allowing damaging metal-to-metal contact and the formation of sludge and deposits. The problem is worse in modern transmissions with more gears, clutch packs and narrow oil passages that require clean, high-quality fluid to achieve maximum performance and life.

AMSOIL Signature Series Synthetic Automatic Transmission Fluid is specifically formulated to withstand the rigors of heavy towing, elevated temperatures and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use and even abuse.

AMSOIL Tech Tip: Transmission Fluid

Proven in 180,000-mile, Severe-Service Taxi Fleet Field Trial
To demonstrate its effectiveness in severe service, Signature Series Multi-Vehicle Synthetic ATF was installed in Las Vegas taxi cabs. The vehicles routinely encountered demanding stop-and-go driving loaded with passengers and cargo, while the desert environment presented extremely hot ambient temperatures, placing enormous strain on the fluid. Following 180,000 miles, a transmission was selected for analysis. The Aluminum Beaker Oxidation Test (ABOT) is an industry standardized test used to determine a transmission fluid’s oxidation resistance, which is a good indicator of its service life. Testing by an independent, third-party lab revealed that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF resisted oxidation longer than required for new fluid to meet the Chrysler ATF+4 specification (see graph). Internal components, including the valve body and clutch plates (pictured), were virtually free of damaging sludge, deposits and wear, confirming the lubricant’s high level of protection for severe-service applications.

Protects Against Thermal Breakdown
Signature Series Synthetic ATF is formulated with high concentrations of antioxidants, making it naturally heat resistant. It provides outstanding protection against sludge and varnish deposits that clog narrow oil passages and contribute to clutch glazing. After 180,000 miles in severe service, fluid analysis revealed Signature Series Multi-Vehicle Synthetic ATF contained 83 percent of its original oxidation inhibitors, proving its long-lasting resistance to thermal breakdown.

Outstanding Wear Protection
Varying speeds and loads causes torque multiplication and extreme stress on gears and bearings. AMSOIL formulated Signature Series Synthetic ATF with high film strength and premium anti-wear/extreme-pressure additives to help prevent wear during severe service. In the industry-standard FZG Gear Wear Test, Signature Series Multi-Vehicle Synthetic ATF that had been used for 180,000 severe-service miles achieved a “Pass” at stage 12 – the highest stage. The results exceeded the Ford MERCON V and Chrysler ATF+4 specifications for new fluid, demonstrating the lubricant’s long-lasting wear protection.

Cold-Temperature Fluidity
Cold, thick automatic transmission fluid lengthens shift times and reduces fuel economy. Signature Series Synthetic ATF is wax-free and delivers extraordinary cold-flow properties. It helps improve shift response, energy efficiency and warm-up times.

Friction Durability
Today’s transmissions are smaller and must withstand higher horsepower and torque while delivering smoother shifts, all with longer fluid life recommendations. AMSOIL Signature Series Synthetic ATF is formulated with friction modifier additives that deliver outstanding clutch-holding capacity (static friction), torque-transfer ability (dynamic friction) and anti-shudder properties (slipping torque-converter clutches). Analysis reveals that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF provides nearly identical friction properties as new fluid for smooth, reliable shifts.
