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.

Extends Drain Intervals

AMSOIL Signature Series Synthetic Motor Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. Signature Series Synthetic Motor Oil is designed to deliver the best possible engine protection, cleanliness and performance over extended drain intervals. It reduces vehicle maintenance and waste oil disposal costs.

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.

Maximizes Fuel Economy

AMSOIL Signature Series Synthetic Motor Oil is designed to maximize energy efficiency for improved fuel economy. Unlike conventional oils, its uniform molecular structure helps it flow more freely and reduce friction between metal surfaces. Anti-friction additives are included to further improve energy efficiency.

Reduces Engine Wear

Signature Series Synthetic Motor Oil provides outstanding anti-wear protection. It has excellent viscosity film strength to separate metal surfaces and robust anti-wear additives to further reduce wear in metal-to-metal contact regions for improved engine life.

Reduces Oil Consumption and Emissions

Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Signature Series Synthetic Motor Oil exhibits an extremely low volatility rate; it controls volatility-related oil consumption and emissions.

Excels in Extreme Temperatures

AMSOIL Signature Series Synthetic Motor Oil resists thermal (heat) breakdown better than conventional oils. It is heavily fortified with detergent and dispersant additives to help prevent sludge deposits and keep engines clean. And unlike conventional oils, Signature Series Synthetic Motor Oil contains no wax, staying fluid in the coldest winter temperatures for easier starting, improved oil flow and reduced bearing wear.

Compatibility

AMSOIL Signature Series Synthetic Motor Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil's life expectancy and reduce the 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.

SERVICE LIFE

AMSOIL Signature Series Synthetic Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline-fueled vehicles as follows:

• Normal Service(3) - Up to 25,000 miles or one year, whichever comes first.
• Severe Service(4) - Up to 15,000 miles or one year, whichever comes first.
• In all non-gasoline-fueled vehicle applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.

*OEM - Original Equipment Manufacturer

(1) Engines operating under modified conditions (non-stock) are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.

(2) Mechanically sound engines are in good working condition and do not, for example, leak or consume excessive amounts of oil, are not worn out, do not overheat, do not leak antifreeze and have properly working emissions control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

(4) Turbo/supercharged engines, commercial or fleet vehicles, excessive idling, vehicles with more than 100,000 miles without prior continuous use of AMSOIL motor oil, daily short-trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.

AMSOIL Ea® Full-Flow Oil Filters are designed for extended change intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea Full-Flow Oil Filters.

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. I have a similar engine identical and 10K builds separate the two vehicles. I do not recommend 0W20 signature oil for use in city driving conditions.

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.

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.

186,000 hard miles, never missed a beat!

I use Amsoil 0W-20 in my daily drivers, a 2008 Scion XD and currently a 2012 Honda Civic coupe. My workhorses receive roughly 110 miles a day / 24 to 26,000 miles a year. The Scion had over 186,000 miles on it when it was involved in an accident and was "totaled" in 2015. The engine never missed a beat, its last duty was to move its smashed up self onto flatbed tow truck.

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.

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.

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.

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
