Product Highlights View Full Description

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.

Protects Your Engine
AMSOIL Signature Series 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 industry-standard Sequence IIIG Engine Test, AMSOIL Signature Series Synthetic Motor Oil delivered 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard.** 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 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 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 pre-ignition 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. Signature Series prevents piston deposits 93 percent better than required to meet the latest API standard.**

Sequence IIIG

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.

APPLICATIONS
AMSOIL Signature Series Synthetic Motor Oil is excellent for use in all types of gasoline-fueled passenger cars and light trucks. It is recommended for all domestic and foreign vehicles requiring any of the following performance specifications:

10W-30 (ATM): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1; GM LL-A-025, 6094M, 4718M; Ford WSS-M2C205-A; Chrysler MS-6395

*All trademarked names and images are the property of their respective owners and may be registered marks in some countries. No affiliation or endorsement claim, express or implied, is made by their use. All products advertised here are AMSOIL-engineered for use in the applications shown.

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 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.

SERVICE LIFE

  • 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.

I changed to amsoil from gm dexos as I wanted something better for my Cruze. After 10k of running dexos as it was included with the car, I switched to amsoil and immediately noticed the engine running quieter than with dexos. I am happy with the change so far and am looking forward to see how it holds up as I only have 1500 miles on it so far. We'll see what happens when I get into my second oil change.

I ran this oil on the 15,000 mile program because I'm on the gas pretty heavy at times. The first cycle went well, but the next cycle I pulled my trailer a lot and the oil was history at 6,000. Truck also had lifter tick at start up when motor was already at running temp. Went back to conventional oil and lifter tick was gone.

This oil, for what I do is excellent. I get between 15000 km to 20000 km before the next oil change and my gas mileage is a little better and the oil filter you only change every second oil change. I would recommend this oil for anyone.
