زيت محركات AMSOIL SIGNATURE SERIES 5W-30 MOTOR OIL – ASL1G

Signature Series 100% Synthetic Motor Oil Advanced Motor Oil Technology

Founded on innovation, AMSOIL introduced the world’s first API-qualified synthetic motor oil. By ignoring commonly accepted limitations and refusing to stop short of success, we set a new benchmark for lubricant performance. These same principles continue to guide our product development, resulting in Signature Series Synthetic Motor Oil. Signature Series is not only the best oil we have ever made, but it’s also better than any competitor oil we 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 protection — and 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 rpm — conditions that encourage engine wear. The camshaft is then measured for wear in 84 locations and an average score is determined.

We 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 wear than required by the industry standard, extending the life of vital components like pistons and cams.

Protects Pistons from Low Speed Pre-Ignition We 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 today’s 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.

Protects Turbochargers Our unique synthetic formulation is inherently stable to resist oxidation and neutralize 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.

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

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 (see image). Its detergent and dispersant additives are so effective, Signature Series provides 90% better protection against sludge.

Trusted by Professional Engine Builders Dedicated engine builders and mechanics put in long hours honing their craft. These architects of powerful, high-performance engines turn to Signature Series to protect their passion.

“When we use AMSOIL, I don’t worry about oil breakdown — and the oil pressure is always consistent. We’ve tested oils back-to-back on the dyno in our shop and we’re always able to make more power with AMSOIL.”

• Brett Bowers, Professional Engine Builder

Extends Drains: Protection Guaranteed AMSOIL Signature Series Synthetic Motor Oil provides reserve protection, allowing you to go longer between oil changes if you choose — up to 25,000 miles (40,200 km), 700 hours of operation, or one year, whichever comes first.

Our unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. Signature Series is designed to deliver outstanding engine protection, cleanliness, and performance over extended drain intervals — guaranteed. It provides peace of mind so you can fit oil changes into your schedule.

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. We 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. Signature Series helped maintain engine performance throughout the 100,000-mile (160,934 km) test.

Better Startup Protection AMSOIL provides better cold cranking viscosity, helping improve wear protection for engine components at startup.

Keeps Pistons Cleaner We 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 304ºF (151ºC), 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, we 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.

Helps Keep Engines Cleaner, Longer AMSOIL Signature Series is fortified with a heavy treatment of detergent additives, delivering 28% more acid neutralizing power than Mobil 1 and helping engines stay cleaner, longer. Testing was conducted in an independent lab using AMSOIL Signature Series 5W-30 Synthetic Motor Oil and a leading synthetic-blend 5W-30 motor oil in Ford F-150 trucks with 3.5L twin-turbo engines.

Service Life

• Normal Service: Up to 25,000 miles (40,200 km), 700 hours of operation, or one year, whichever comes first, in personal vehicles not operating under severe service.
• Severe Service: Up to 15,000 miles (24,140 km), 700 hours of operation, or one year, whichever comes first. Severe service conditions include commercial or fleet vehicles, excessive idling, or frequent towing, hauling, plowing, or driving in dusty conditions.
• Modified engines (non-stock), racing vehicles, and vehicles using alternative fuels (E85, CNG, propane, etc.) are excluded from extended drain interval recommendations.
• Change at the vehicle manufacturer’s recommended drain interval outside the U.S. and Canada.
• AMSOIL Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles (19,312 km) or one year with other brand filters unless longer intervals are recommended by the vehicle manufacturer. Always change the filter when changing oil.
• Check oil regularly to maintain proper fill levels. AMSOIL Oil Filters stop smaller particles, flow more oil, and last longer than regular filters. For best performance, use AMSOIL Oil Filters.
