Signature Series 0W-20 Synthetic Motor Oil 

One of the top sellers in the Omaha store! I use this in my ford Inline 4 EcoBoost which calls for a 5W-20 which is great but a 0W-20 is even better. It replaces all 5W-20’s as well as over performs any 0W-20 on the market. A true 100% synthetic which is guaranteed to hold its grade. Unlike our competitors this oil will not clog up your intake system via vapors in the PCV.  On direct injection engines (DFI) you must use the cleanest synthetic possible. Ours is the only true 100% synthetic 0W-20 that I know of currently so it solves problems, saves fuel and extends engine life.

Protects Against Engine Wear

0W-20 Signature Series Synthetic Motor oil ASMAMSOIL Signature Series Synthetic Motor Oil develops a strong fluid film that keeps metal surfaces separated while 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 percent 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

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 percent protection against LSPI1 in the engine test required by the GM dexos1 Gen 2 specification – zero occurrences were recorded throughout five consecutive tests.

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 2000 cycles of extreme heat soaks. An oil must limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, protecting the turbocharger 72 percent better than required2 by the GM dexos1® Gen 2 specification.

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

Horsepower increased thanks to AMSOIL Signature series

Note: Hotrod Magazine duplicated these results in a recient article using a Dodge Charger. Four extra horses and increased torque over the Mopar brand.

 

Limits Oil Consumption

Signature Series 5W-30 has a uniform molecular structure that limits evaporation and keeps it where it’s needed most – protecting your engine. Volatility (burn-off) occurs when oil gets hot, causing lighter molecules to burn off or evaporate. This leads to oil thickening, additive imbalance, higher emissions and oil consumption. The NOACK Volatility test is the industry standard for evaluating motor oil high temperature evaporation. It measures the percentage of burn-off after a motor oil is placed under constant airflow at 482ºF for 1 hour. A lower number indicates a better resistance to evaporation. Signature Series falls far below the API limit for volatility, reducing the need for frequent oil top-offs and limiting vehicle emissions.

less oil consumption

Easier Cold-Starts

Signature Series Synthetic Motor Oil does not contain paraffins (wax) and stays fluid in temperatures of -58ºF (-50ºC) and lower. Extreme cold causes other motor oils to thicken, starving vital moving parts of lubrication, accelerating wear and even preventing vehicles from starting. Signature Series provides 66 percent better cold-temperature performance for easier starting, better fuel economy, improved oil flow (as seen below) and reduced wear.

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 percent cleaner pistons than required by the standard.1

The better alternative

So many pickup trucks and SUVs require 8-quarts of 0W-20 (buy 2-gallons for convenience) . The manufacturer did this due to the need for additive packages to last longer. As you can see above new and future engines need the oil to do more, the OEM want’s engine life to earn them a higher place with consumers. This is one way to do that and with AMSOIL you can clearly go that extra distance without any worry they tried to work around!!

Customer Reviews:

Tony – Gatortail

My order arrived on time and un-damaged. I use Amsoil in my Gatortail engine (Briggs) replacing the oil at 25-35 hours with a total of 550 hours on the engine. The oil holds up very well. When conducting maintenance on the engine the interior working parts of the engine are like new with absolutely no visible signs of sludge build up. I highly recommend the use of Amsoil products. I also use the Amsoil Marine Grease in the lower unit and that product holds up very well as well.

 

David – Amazing synthetic oil.

I swear by this oil. Simply the best fully synthetic oil out there. I got 220000 miles on my Altima and still has great fuel mileage and power.

 

Jeremiah – Best in the World by Far!

The most superior motor oil in world! It actually last 25,000 miles in my 2009 Toyota Venza and 2007 Chevy Malibu! When I drain it at 25,000 miles it doesn’t look like its even lost its viscosity or characteristics! Best oil on the planet!

By  Howard,  a  Verified Buyer  on  October 24, 2019
I have been using this this in all my vehicles since 1992. In my new cars I change to Amsoil at the first oil change. when I retired from Work Jan 2012 I was driving a Dodge Neon, 4 cyl standard shift. I drove 98 miles round trip every time I went to work. Used this Amaoil and also put Amsoil in the manual transmission. I had 160,00 miles on it when he flew to Fla from Pa to pick it up. He is still driving it. Drives up the Pa turnpike every day. He turned over 300,000 miles on it about 5 months ago. Still has the original clutch.
Great Oil

Great Oil, use it in all my LS motors. Many of them have exceeded 300,000 miles already

Signature Series cleans up the competition

In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.

TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.

The TBN Test

The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.

AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing power1 than Mobil 1, and 36% more than Royal Purple, helping engines to stay cleaner, longer.

Meanwhile Schaeffers has their dealers trying to convince you by using that 1940’s stationary bearing unit which is for grease and any oil can pass if you have the wrong additives. (It’s like watching Tim Conway doing his old man routine.)

The AMSOIL Advantage

AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection. AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM D2896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals.

1Based upon independent testing of Mobil 1 Annual Protection Full Synthetic 5W-30, Royal Purple High Performance 5W-30 and AMSOIL Signature Series 5W-30 in ASTM D2896. Oils purchased 05/03/18.

Local Omaha note: The performance you get with AMSOIL justifies the extra cost although our XL product line which is similar costs less than several ones on the chart above.  If you are not looking for optimum performance or protection or extra years on the car then save your money and buy Dollar General’s motor oil.  If the public strictly bought on the merits of truth and disclosure, AMSOIL would out-sell the rest.
