In the 35th year - Mr. Amatuzio (AZO for Amatuzio Oil) has once again demanded his staff to improve the top engine oil performer to the ultimate in wear protection and engine cleanliness without effecting price. We introduce the first addition to the "Signature Series" with the upgraded 0W30 (AZO). With the 0W30 you get the best in winter protection too with increased flow to the filter at start-up not to mention the standing film strength no other oil can match.

Extends Drain Intervals

The key here is Oxidative Stability & Resistance to contaminants.
AMSOIL Signature 0W-30 Synthetic Motor Oil lasts much longer in service than conventional oils. Its unique synthetic formulation and long drain additive system resist oxidation and neutralize the acids that shorten the service life of other oils. AMSOIL Signature Series 0W-30 delivers the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

Maximizes Fuel Efficiency

The lightweight molecular structure of AMSOIL Signature Series 0W-30 Synthetic Motor Oil reduces energy loss from the “drag” common to high viscosity oils. It is fortified with additives that enhance its friction-reducing properties to help further improve fuel efficiency.

Reduces Wear

0W30 will keep your engine preserved but I use it because it just drives better and I no longer have to stress oil service at 5000 miles.AMSOIL Signature Series 0W-30 Synthetic Motor Oil contains specialized anti-wear technology. Its durable, high temperature film strength effectively separates metal surfaces to reduce wear even under the most grueling conditions. Tests prove that AMSOIL Signature Series 0W-30 provides better protection against wear than other motor oils (see graph). AMSOIL Signature Series 0W-30 helps engines last longer.
Dealer's note: Many competitors are switching to lower cost additives to keep stockholders happy thus the significant drop in performance and customer satisfaction. They also won't provide engine tests because it cost less to just run ads and issue 1/2 truths.

Resists Heat, Reduces Oil Consumption and Emissions

AMSOIL Signature Series 0W-30 Synthetic Motor Oil is thermally stable with a strong resistance to high temperature volatility (burn-off). It is heavily fortified with detergent and dispersant additives designed to prevent sludge deposits and keep engines clean. Low volatility and clean operation reduce oil consumption and emissions.

Provides Outstanding Cold Flow Properties

AMSOIL Synthetic 0W-30 Motor Oil is highly shear-resistant. With AMSOIL Synthetic 0W-30 Motor Oil's excellent viscosity retention, the protection that goes into the engine is the protection that stays in the engine, even over an extended course of severe service. Unlike conventional oils, AMSOIL Signature Series 0W-30 contains no wax. Its exceptional -60°F cold flow properties ease starting and reduce bearing wear.


AMSOIL Signature Series 0W-30 Synthetic Motor Oil is recommended for use in gasoline engines, diesel engines (API CF, ACEA B5) and other applications requiring SAE 0W-30, 5W-30 or 10W-30 with the following worldwide specifications:

0W-30 (AZO): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1; Ford WSS-M2C946-A, WSS-M2C929-A; Chrysler MS-6395N; Suitable as a replacement for GM dexos1™ (supersedes LL-A-025, 6094M and 4718M)

AMSOIL Signature Series 0W-30 is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil 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 motor oils.



AMSOIL Signature Series 0W-30 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.
  • Replace AMSOIL Ea oil filter at the time of oil change up to 25,000 miles or one year, whichever comes first (other brands at standard OEM* intervals).
  • 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 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 oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.

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

(4) Turbo or supercharged vehicles, commercial or fleet vehicles, extensive engine idling, first and subsequent use of AMSOIL in vehicles with over 100,000 miles, daily short trip driving less than 10 miles (16km), frequent towing, plowing, hauling or dusty condition driving.

AMSOIL Ea full-flow oil filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea full-flow oil filters.

"What?? You're trying to talk me into a 0W30 over my factory recommended 5W30? Why it's too thin! And it's not that cold in my climate!!"

The above is a typical and understandable response to our suggestion to upgrading to AMSOIL's best. But really our 0W30 is just a better performing oil for ALL applications.

But to better answer the concerns of the customer - the 0W30 isn't thin. The "W" or winter grade is a measure of cold cranking torque. Please read the following:

Winter (“W”) viscosity grades are determined using the Brookfield Cranking viscosity and Brookfield Pumping viscosity tests. The Brookfield Cranking viscosity test evaluates the amount of energy it takes to start an engine at a specified cold temperature; the lower
the winter grade, the lower the temperature at which the Cranking test is performed.

The Brookfield Pumping viscosity test evaluates the amount of energy it takes to pump an oil at a specified cold temperature; the lower the winter grade, the lower the temperature at which the
Pumping test is performed. For example, the 25W viscosity grade has the least rigorous temperature requirements for pumping viscosity (60,000 cP at -15°C) and the 0W grade has the most rigorous pumping viscosity requirement (60,000 cP at -40°C). Brookfield
Viscosity is measured in centipoise (cP).

Your 0W30 oil viscosity is better than a 5W30 - here's one reason why.

In addition to the Kinematic viscosity requirement, each viscosity
classification (SAE 20, 30, 40, etc.) has a high-temperature/high-shear (HTHS) requirement. The HTHS test simulates an engine operating at high temperatures and load, to measure how well the oil maintains a lubricating film in severe service. The higher the viscosity grade, the higher the HTHS viscosity value.

As A.J. Amatuzio neared the end of his 25-year career as an award-winning jet fighter pilot, he set his sights on a new challenge. Knowing that every jet engine in the world used only synthetic oil, he was convinced that the same type of technology would provide tremendous benefits to automotive engines. In the early-1960’s he set out on an intense period of research and development.

In 1972 A.J. Amatuzio created AMSOIL INC. and introduced the world’s first API qualified synthetic motor oil, AMSOIL 10W-40. But obstacles remained for Amatuzio. The major oil companies were threatened by his advanced technology and, along with the auto manufacturers, refused to acknowledge his revolutionary new product.

Amatuzio persevered. Through sheer determination he began to convince the motoring public that AMSOIL synthetic motor oil was far superior to the conventional petroleum oils they had been using. Then, as consumers caught on by the thousands, the competing oil companies could no longer deny the performance benefits of AMSOIL motor oil. They were forced to follow the AMSOIL lead and, one by one, developed synthetic oils of their own. Amatuzio had humbled an industry.

Today, AMSOIL remains the leader in quality and innovation. A.J. Amatuzio Signature Series Motor Oil is engineered with the world’s most advanced synthetic base oils and high-performance additives. This exclusive formulation represents the benchmark in motor oil technology and sets the standard by which all other motor oils are measured.


Amsoil AZO Signature Series 0W30 can be described as the ultimate product by the descriptions above but in our own use over the years this is the oil which the level of performance goes beyond what the intended purpose can describe. If I could sell this product on one point or one word I would say 'free' meaning on a stick shift car where you can feel the acceleration best, you will instantly take notice the improvement of the free revving nature and smoothness of the engine.
We get plenty of feedback from our new customers with the same opinion.

I would have to say AMSOIL 's 0W30 has done more for word of mouth sales than any other passenger car oil that we sell. If you are an enthusiast behind the wheel of any modern car why not see for yourself? Ask for AMSOIL AZOQT-CA - that's the 12 quart case - best price...
