Product Description
AMSOIL Signature Series Synthetic Motor Oil delivers extraordinary lubrication in all types of automotive gasoline engines. By combining industry-premier synthetic technology with AMSOIL premium additives, Signature Series Synthetic Motor Oil exceeds the higher performance demands of modern engines. It withstands the stress of higher horsepower, higher heat and complicated emissions control systems. Signature Series Synthetic Motor Oil is engineered to outperform competitive conventional and synthetic motor oils. It delivers long-lasting performance and protection.

AMSOIL, the leader in automotive synthetic lubrication, produced the World's first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, the First in Synthetics®, to do the best job protecting your engine.

Protects Against Engine Wear
AMSOIL 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 industry-standard API SN 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 wear* than required by the industry standard, extending the life of vital components like pistons and cams.

*Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by the API SN specification.

Protects Pistons from Low-Speed Pre-Ignition (LSPI)
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.

Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. The GM test allows up to five LSPI events to receive a passing score. Signature Series Synthetic Motor Oil provided 100 percent protection against LSPI* - zero occurrences were recorded.

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 required* by the GM dexos1® Gen 2 specification.

Extends Drains: Protection Guaranteed
AMSOIL Signature Series 25,000 miles drain interval technologyAMSOIL Signature Series Synthetic Motor Oil provides reserve protection, allowing you to go longer between oil changes if you choose up to 25,000 miles, 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.

Oil Filter:

Any brand of oil filter may be used with Signature Series Synthetic Motor Oil. For maximum convenience, however, use an AMSOIL Ea® Oil Filter. Made of fully synthetic media with greater filtering efficiency and dirt-holding capacity than conventional filters, Ea Oil Filters are recommended for 25,000 miles/12 months or 15,000 miles/12 months, depending on application, which coincides with Signature Series' once-a-year drain interval. While Signature Series' 12-month service life remains intact if a non-Ea Oil Filter is used, the filter must be changed according to its manufacturer's recommendations.

Trusted by Professional Engine Builders

Engine Masters ChallengeDedicated 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 a film breakdown or an 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, Engine Masters Competitor and Professional Engine Builder

Maximum Cleaning Power to Battle Sludge

AMSOIL Signature Series offers Maximum Cleaning Power to Battle SludgeAMSOIL Signature Series Synthetic Motor Oil has 50 percent 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 percent 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 percent better protection against sludge.

Preserves Horsepower
The extreme durability of Signature Series Motor Oil ensures your engine runs 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. 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 test.

Limits Oil Consumption
Signature Series 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 482°F 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.

noack volatility test results

Easier Cold-Starts
Signature Series Synthetic Motor Oil does not contain paraffins (wax) and stays fluid in temperatures of -58°F 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.

pour point test results

Maintains Protective Viscosity
We formulated Signature Series with superior thermal durability that resists breakdown better than conventional and synthetic motor oils. The Sequence IIIH Test uses the Chrysler 3.6L Pentastar engine to evaluate a motor oil's ability to resist the damaging effects of heat. The test is conducted with oil temperatures of 304°F, 100°F hotter than normal operation, to accelerate oil thickening and deposits. Despite the extreme conditions, Signature Series kept pistons clean and held thickening to only 6 percent, a minimal amount compared to the proposed specification limit of 150 percent*. This stay-in-grade performance helps maintain maximum power and fuel economy while also ensuring advanced technologies like variable valve timing (VVT) operate as designed throughout the entire drain interval.

SERVICE LIFE
Normal Service: Up to 25,000 miles, 700 hours of operation or one year, whichever comes first, in personal vehicles not operat-ing under severe service.

Severe Service: Up to 15,000 miles, 700 hours of operation or one year, whichever comes first. Severe service conditions include commercial or fleet vehicles; excessive idling; or frequenttowing, 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 U.S. and Canada.
• AMSOIL Ea® Full-Flow Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles or one year with other brand filters unless longer intervals are recommended by the vehicle manufacturer. Always change filter when changing oil.
• Check oil regularly to maintain proper fill levels.

AMSOIL Ea Full-Flow Oil Filters stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea Full-Flow Oil Filters.

COMPATIBILITY

AMSOIL Signature Series Synthetic Motor Oil is compatiblewith other conventional and synthetic motor oils. Mixing other oils with AMSOIL motor oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.

Decades of entrusting my vehicles to Amsoil

I have used Amsoil engine oil and oil filters for the better part of each decade dating back to the 1980s. I have had my vehicles serviced at Honda dealerships since then. Most of the time that I have had a few major engine services performed, I have asked about the condition of the engine and the oil and have always received a positive report.

Currently, I drive a 2015 Honda CR-V. I believe that its average fuel economy of ~31mpg in a combination of city & highway driving is attributable to the Amsoil "Signature Series 0W-20 Synthetic Motor Oil" that I run in my CR-V's engine.

LOVE IT

I used this oil in my 2013 Toyota FJ Cruiser, which I use as my off-road vehicle and my daily driver. Compared to the other most recommended oil in my community, I found Amsoil to perform better. You may ask how I know it performs better. Well, I have been working on my family's cars since I was 13, so for about 33 years. I live where temps range from wind chill of -20F to heat index of 115F, and some days in the year the actual high between two days will change 40F. So how do I know it performs better? I can hear it, and I can feel it. I know that sounds silly, but growing up with a car that broke down 40 times in the first 4 years that I had it, I became very in tune to the sounds and feel of vehicles. Amsoil engine oil made my engine run quieter (on a 40,000 mile engine) and smoother (feel it in the pedal and floor vibrations from the engine bay).

The best oil money can buy.

Years ago I read a synthetic oil life study. The study was very thorough, using different brands of oil, and filters. Amsoil came out on top.

Another thing discovered during this study was shocking. Changing your oil increases engine wear. The oil changes we're done when the TBN reached a low level, and the first sample analyzed after the change always showed higher levels of wear metals. This abated by the second sample.

My Subaru Forester is the first new automobile I've purchased. I need it to last a long time. I'm running Amsoil signature, and a bypass filter. I'm going to have the oil analyzed regularly, and base the change interval on the results.

I hope it will last the rest of my life. I'm 63, so I've still got aways to go.

Metal wear noted at 217 hours of use

Stopped using AMSOIL due to metal wear. The engine have never shown metal wear in testing with previous oils of different brands. The oil also changed viscosity and lost about 1/2 quart.

Want the best

The MFGs new oil specs leave me a little concerned about trading engine life to increase gas mileage.
Personally I would rather loose a few miles per gallon and be left with a longer lasting engine.

Considering my new Subaru Outback is under warranty I will use there recommended oil viscosity of 0-20.
But I have to admit I am not convinced an oil this thin is the best for any motor.

So if I must use an oil this thin I want the very best oil I can buy.
I turned to Amsoil for protecting my motor.

My annual oil change

When I bought my '13 Subaru Empreza, the dealer said that the engine must use synthetic 0w-20 oil, so I of course chose Amsoil's 0w-20 Signature oil. FYI this car is suppose to have a high oil consumption engine, but I have never added any oil. Another thing the dealership told me is NEVER EVER USE MOBIL 1 oil as it will wreck the automatic cam timing mechanism.

Amsoil works!

This is the second time I have filled my 2012 Toyota Tundra Crew with 0W-20 synthetic. Even though it takes 2 full gallons for a fill up its well worth the time and cost. This oil only has to be changed out once a year or within an extended driving distance, or hard service. My Tundra does see off road quite often and I've never had a worry about over heating or an other oil related issues. With a long life oil filter and air filter changed at the same time, I only have to change fluids once a year. That's awesome, as I travel quite often as a wounded Veteran, going to WWP events and also using my truck for Team Rubicon disaster relief efforts. The sticker on the window gets the word out, the truck running flawlessly is all the proof I need. I'll keep using it as long as you guys keep making a great product.

0W-20

I did an Amsoil flush and used this 0W-20 in my 2012 Acura TL with 45,000 miles on it right away you can hear the little bit of lifter ticking I had went away. Amsoil is amazing and there's no way I would ever use any other oil on any of my vehicles. I would suggest it to anyone and everyone it is simply the best!

2002 3/4 Ton Suburban LT with 8.1 L

I have used Amsoil products in all my vehicles for many years. With my latest purchase I felt it was time to let people know how great these products are.

I was shopping for a new tow vehicle for our family. We love Suburbans however to get one that would meet our needs we had to go shopping for an old one as 2001-2006 were the only years a Burb could tow 12,000 pounds if it had the 8.1 L engine.

There was no way I could talk my wife into a pick-up truck or a diesel so I was left with one choice and believe me they are had to find as few were made and many of those are long out of commission or in very poor shape.

As much as I was looking forward to a stronger tow vehicle I was dreading what the fuel economy would be. I finally found one in North Bay, Ontario but I lived just outside of Calgary, Alberta.

Before flying out to Ontario to pick up the truck I called the closest Jiffy Lube in Sudbury, Ontario and arranged for them to order in all the Amsoil products I wanted so they could change all the fluids in the truck before I drove the 3000km home to Alberta. I did everything, engine oil and filter, transmission, transfer case, front and rear differential, and coolant. It took about 3 hours to complete.

I hit the highway as soon as they were done. I have always been meticulous about keeping track of my fuel economy and I was curious how bad it would really be. I have read that 10-12 MPG Imp. is average unloaded and 6-8 MPG Imp. towing was what I should expect.

Wow, was I surprised!

I had about 500 lbs of cargo in the truck with no passengers. Most of the long trip I averaged about 55-60 MPH. My average fuel economy for the entire 3000km trip was 17.5 MPG Imperial. Even one MPG more with a 7500 lb truck is something to get excited about. I do not think it is possible to attain fuel economy like this with out Amsoil, no matter how nice you drive.

I can't wait to see how it does on its first towing trip!

Thanks for making such great products.

I will definitely be using Signature Series in my 2016 Honda

So far the Signature Series 0w-20 oil is doing great in my 2016 Honda Accord 6-speed manual.
My first oil change was at 5,000 miles and my mileage as gone from 35+ to 39+ mpg. I'm sure that Amsoil had something to do with it. Car runs smooth and strong. Almost ready for my next oil change.
I'll be using the Signature Series in my Honda from now on.

Amsoil worked fantastic in my old 2003 VW Jetta TDI which had over 360,000 miles when I sold it and my friend who bought it from me will be using Amsoil in it as well (now has over 375,000 miles).

I'll be switching my Ram 6.7L Cummins 6-speed to Amsoil next change as well.

Though a little pricey, Amsoil makes good products that definitely protect your investment.

Use in my 2015 Yukon SLT-This is used primarily as my field service vehicle. I cover the Bay & Reno area & to date have 42,000 miles on my SUV. I frequently haul loads from a 1000 pounds & tow up to 3000 on occasion. I find it very hard to trust Oil Change facilities & the dealer takes all day so I change the oil myself knowing that I am using the best oil money can buy because I have tried the rest & Amsoil is the best.

Amazing Vale

My wife puts 250 kms a day on her 2010 Prius and I was tired of paying $100 for a 0W20 oil change at a drive thru every 7 weeks. Bought this Amsoil for its claim of extended oil change intervals. Yes it's more expensive initially with an EA oil filter, but when only changing oil every 35000 kms the savings add up. No oil loss during that time or any adverse experience. My 2000 Jetta TDI with over 500,000 kms was always serviced with Amsoil products and at extended intervals. Still running perfect every day.

Long time user of Amsoil products

I've used Amsoil for about 30 years now. Used cars and new. My first oil change in the new car gets the Amsoil, and never anything else after that. I've had no maintenance issues due to oil in any of my vehicle, ever, and I actually run them for the full year or 25,000 miles as advertised. One of my vehicles is a Subaru, which calls for synthetic right from the start. I used to let the dealer do the oil changes, including using their own preferred oil brand, but I swear, when I switched it over to Amsoil it actually runs smoother and quieter. I don't know how or why, but it is what it is! My sons and my brothers use it as well. same results.

So far so good

i was already using 0-20 in my Toyota and my Subaru, so I didn't really notice a difference in mileage. Oil analysis suggests the extended oil changes are easily doable, but I'll do another at 25000 to make me feel better. Swapping just the oil filter isn't bad at all........just not what I'm used to.

Been using Amsoil products on 3 service vehicles for a 20 year period and received 256K on my truck, 278K on my passenger car and 146K on my motorcycle. I know these products had a lot to do with those totals. Wouldn't use any other Brand EVER!

cost

People tell me they don't use amsoil because of the high cost. But if you change the oil at 30, 000 mile intervals like I do, it actually costs LESS than paying for an oil and filter change every 5, 000 miles. And changing the micron filters every 10 to 15 thousand miles is very easy to do, plus you are getting a much better product using a full synthetic oil and your car's engine will last a lot longer. That's why all Nascar drivers only use a full synthetic oil. That's why jet airplanes only use a full synthetic oil. The protection, even at extreme temperatures is unparalleled. I had a real estate client who operated a fleet of 18 wheelers. He was so cheap he would change the oil at 100, 000 intervals, but he would change filters and do oil analysis along the way. But, my point is if he could operate all those trucks on a 100, 000 mile oil change schedule, it's really no problem for a passenger car to change oil at 30, 000 mile intervals because unlike regular oil a synthetic does not break down. The key is to do the micron filter changes on schedule, which usually require you add ftom a half quart to a full quart of oil at that time.

Best 0w20 - Cheap insurance against engine wear

0w20 are the lowest viscosity oils currently used for cars. The upside is better fuel economy due to lower drag, therefore less energy wasted to pump oil inside the engine.

However, the downside is, lower viscosity oils does not protect critical components at high heat & high stress situations. The oil is too thin. The film of oil that keeps two moving parts from touching each other easily burns off due to lower film strength. This results in accelerated wear!

With research, I have found that Amsoil's signature series 0w20 is the only oil that can provide adequate levels of protection. If your driving a vehicle that requires 0w20 or 5w20, then look no further, get this 0w20 motor oil or the Amsoil signature series 5w20. These two oils will help your engine see high mileage before requiring major repairs. Use the "best money can buy" 20 weight oil as a cheap insurance against engine wear. Do not bother with lower grade oils or even Amsoil's own XL or OE series oils.

Improved gas mileage by more than 100km's per tank

I installed Amsoil 0W-20 Signature Series in my 2011 Honda Odyssey with about 30,000 km's. Prior to this, it was running on dealer installed oil.

With Amsoil the average fuel consumption meter dropped from 13.5L/100km to 11L/100km for the exact same weekly driving routine (lots of in town driving).

This translates to about 125km more driving range for a tank of 80 litres. That's about $15-20 in fuel savings per fill up. I do about 30 fill ups per year. So the total savings is about $450-$600.

I only spent about $50 for 5 bottles of Amsoil 0W-20 ASM, which will last me a year, while saving 10 times that in fuel!!! Never thought motor oil can do so much. Thanks to Amsoil
