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.

This rocks!

Use this for our 2009 VW Routan SEL Premium with 4.0L, and the van loves it! We have taken it up and down west coast numerous times without an issue!

Best Oil Always

Signature series has always held the highest protection standards for engine oil. Never an oil problem, and knowing that you are protecting the powerplant for your vehicle is so important nowadays.

I would buy this product again and again

I have used Amsoil products on both my motorcycle (2012 Victory Cross Country Tour) and car (2007 Dodge Magnum SXT) for many years, after the initial NEW break-in of their engines. This is an excellent product that I would recommend all to use.

Tried and true go to oil

This is a great fully synthetic oil that never disappoints. I love the extended change intervals that I get with this product. I can run this oil for extended drain intervals and not worry one bit due to the quality of this product.

The most important thing you can do for your car.

The three most important things you can do for your car: warm it up, drive slowly as the moving parts warm up, and change the oil regularly. Since I wanted my Toyota truck to last, and I hate to change the oil, I use Amsoil. It's superior, and it only has to be changed once a year. Really! I ran fossil oil until after the engine was broken in, like 25,000 miles or so, then Amsoil for engine, trannie and differential since then. I bought my truck new in 1998, and it now has 344,000 miles on the original motor and trannie. Everyone who knows, knows Amsoil is far and away the best.

This is all I use

I have been a preferred customer since 1989. All my vehicles, Cars and Pick ups have the 10w-30 signature since new. 200K miles plus on each, and still running strong. Replaced a valve cover gasket on a 1993 Chevy 4 cyl. with 180K miles, top of cyl. head brand new with no gunk. Was using the Amsoil By-pass system with this car.

Great Product

I have been using Amsoil on all my vehicles for a couple of years. I really enjoy the extended change intervals and the protection Amsoil provides. This is the only oil I will use. Engines seem to run a lot smoother and gas mileage has increased a bit.
