AMSOIL 5W-30 Signature Series 100% Synthetic
The Next Generation in Motor Oil Technology
AMSOIL Signature Series Synthetic Motor Oil is engineered to outperform conventional and synthetic motor oils. It combines industry-premier synthetic technology with AMSOIL premium additives in a unique formulation that exceeds the higher performance demands of modern engines. Signature Series delivers the performance and value upon which the AMSOIL reputation is built. The culmination of more than 40 years of expertise, its exclusive formulation raises the bar for motor oil performance.
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.
Nothing is held back in the additive blend for this and other Signature Series products. This is why it’s the best in the industry. I’ll quote AMSOIL’s Vice President Dean Alexander, “When selecting additives and base stocks we are the only company who avoids making decisions based on cost. If there is a better product or a trend for something better AMSOIL is known in our industry to be the first to get it to the consumer with our legendary blending experience. That is our business, the business of being the best, not turning profits for share holders.”
You can also see this technique being used in the Absolute Efficiency Oil Filters.
Protects Your Engine
AMSOIL Signature Series Synthetic 5W-30 Synthetic Motor Oil provides outstanding anti-wear protection. It 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. In the Sequence IIIG test, which is normally run for 100 hours, AMSOIL Signature Series Synthetic Motor Oil delivered outstanding wear protection for the camshaft and lifters, even after doubling the test interval to 200 hours. For details, see the Double-Length Sequence IIIG Engine Test Technical Study (G3320).
Maximizes Fuel Economy
Signature Series Synthetic Motor Oil is designed to maximize energy efficiency for optimum 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.
Extends Drain Intervals
AMSOIL 5W-30 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 is designed to deliver outstanding engine protection, cleanliness and performance over extended drain intervals. It reduces vehicle maintenance and waste oil.
Keeps Pistons Clean
Excess piston deposits can lead to preignition and engine knocking, which results in lost power, reduced fuel economy and, in severe cases, engine damage. Signature Series’ premium additives and naturally high resistance to extreme heat help keep pistons clean for maximum engine performance. After a double-length, 200-hour Sequence IIIG engine test, Signature Series demonstrated outstanding cleanliness properties and shattered the requirements of a 100-hour test.
Excels in Extreme Temperatures
Signature Series resists thermal (heat) breakdown better than conventional and synthetic motor oils. It is heavily fortified with detergent and dispersant additives to help prevent sludge deposits and keep engines clean. Unlike conventional oils, Signature Series contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow and reduced wear.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. Signature Series resists volatility better than other oils, helping reduce oil consumption and emissions.
AMSOIL Signature Series Synthetic Motor Oil is excellent for use in all types of gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:
5W-30 (ASL): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1; Honda HTO-06; Ford WSS-M2C946-A, WSS-M2C929-A; Chrysler MS-6395; GM dexos1™ (supersedes LL-A-025, 6094M and 4718M) Fortified with detergents that exceed dexos1™ sulfated ash specifications.
“Just by switching I first noticed the engine seem to run as smooth as glass. Suddenly I realized why AMSOIL products stand alone in quality. You won’t realize the coarseness or vibrations within the motor until they are gone. AMSOIL 5W-30 Synthetic Motor Oil was worth every sent! I since have upgraded to the 0W-30 which seems to have even more performance.” – Typical customer feedback
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 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.
- Normal Service – Up to 25,000 miles, 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, 700 hours of operation or one year, whichever comes first.
Severe Service: Primarily short trips (less than 10 miles [16 km]); turbo/supercharged engines; commercial or fleet vehicles; excessive idling; first-time use of AMSOIL motor oil in a vehicle with more than 100,000 miles; frequent towing, hauling, plowing or driving in dusty conditions.
- Modified engines (non-stock) and those using E85 fuel are excluded from extended drain 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 change intervals. With other brands, do not exceed six months or 10,000 miles unless longer intervals are recommended by the vehicle manufacturer.
- Check oil regularly to maintain proper fill levels.
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.

My oil of choice
By Mark 12/24/2016
On a friends recommendation I switched to Amsoil for use in my 2005 Jeep Liberty Diesel. I sold the Liberty after 3 years but have continued to use Amsoil products in all of my Vehicles, generators, lawn tractors, push mowers, and snow blower. The Signature Series 5W-30 is my oil of choice for my GMC Sierra, and my wife’s
Lincoln MKX. I highly recommend trying all of Amsoil’s products, everything I have tried I have been completely satisfied with, oils, grease, sprays, fuel additives, filters, ect….
The Best Lifeblood for your Vehicle!

I use Amsoil 5W30 Signature Series in all 3 of my vehicles. After using the 10W40 in my motorcycle and watching the “White Papers” comparative study on 5W30 motor oils done by a reputable 3rd party test lab I was convinced that this was the best oil on the market. And they don’t have other product lines to fall back on if sales don’t demonstrate it is a quality product. The “White Papers” comparative study results really says it all. I am an Amsoil customer for life and have also convinced a family member who also happens to drive one of the vehicles in our family that you cannot lose but only win with Amsoil. He is sold on it too!
