SAPS Levels Are An Important
Differentiator In European Specifications
Makes It Easy By Clearly Defining SAPS Levels In Its European
Car Formula Line.
Technical Product Manager,
The March 2011
Tech Talk Column described how automotive industry trends
and governmental regulations to reduce exhaust emissions are
forcing sulfated ash, phosphorus and Sulfur (SAPS) levels
In engine oil downward. SAPS are common oil additives that
provide desirable performance properties, including detergency
and protection against wear and oxidation. But they can also
reduce the performance or longevity of exhaust treatment devices
such as diesel particulate filters (DPFS) and the three-way
catalysts used in the catalytic converters of newer gasoline-powered
vehicles. High levels of sulfated ash can clog DPFS and reduce
fuel economy and engine performance, while phosphorus and
sulfur can deactivate catalyst sites, decreasing the effectiveness
of catalytic converters and allowing unwanted emissions into
in today's smaller, high-horsepower gasoline and diesel-powered
engines, while still protecting their vital operating components,
is a continuing challenge for OEMS and lubricant manufacturers.
This is particularly true because there is no one-size-fits-all
motor oil when it comes to SAPS levels. The European Automobile
Manufacturers' Association (ACEA) establishes lubricant standards
for Europe, similar to the American Petroleum Institute (API)
here in the States. Previously it was possible for the same
motor oils to be used in applications calling for different
SAPS levels because there was no lower limit. Until recently,
a low-SAPS oil could be used in a mid-SAPS application, and
a mid-SAPS oil could be used in a full-SAPS application. Current
ACEA specifications create three clearly defined categories
for SAPS levels and eliminate backward compatibility. This
required a third AMSOIL European motor oil formulation to
cover all three SAPS levels outlined by ACEA and vehicle manufacturers.
The best SAPS level
for a vehicle depends on several factors. Gasoline and diesel
engines with emissions systems that are sensitive to the SAPS
content of oil require lower SAPS formulations to properly
function for a long period of time. These oils are engineered
to the exacting engine oil specifications Of ACEA and European
OEMS to ensure they are compatible with current emissions
systems while still providing engine protection. This is very
difficult to accomplish because although lower SAPS levels
provide the best emissions systems protection, it costs much
more to achieve equal engine protection with low SAPS content.
Lower SAPS oils rely on different properties to provide proper
engine protection, while still promoting long emissions system
life. As a result, as SAPS levels go down, finished-product
pricing goes up.
Not all engines
are best served by low- or mid-SAPS oils. Older vehicle designs
rely on oils with fUll SAPS content to protect components
properly and usually do not have advanced emissions systems
that are sensitive to the extra additives. Additionally, fuel
quality has a major Influence on the recommended SAPS level.
Fuel quality varies regionally and is often related to the
ethanol or sulfur content in gasoline or diesel. Many new
vehicles also require full-SAPS engine oils because they are
better suited to address those issues.
Because of these
changes in specifications, AMSOIL revamped its European Car
Formula lineup. The two existing products, European Car Formula
5W-30 Low-SAPS Synthetic Motor Oil (AEL) and European Car
Formula 5W-40 Mid-SAPS Synthetic Motor Oil (AFL), now have
updated labels with clearly defIned SAPS levels and some specification
realignment per the new European specs; however, the formulations
remain unchanged. The new European Car Formula 5W-40 Full-SAPS
Synthetic Motor Oil (EFM) is also a 5W-40 because that viscosity
category continues to be the most recommended by European
SAPS levels are
not an indicator of quality. All three European Car Formula
Synthetic Motor Oil formulations are premium and deliver premium-grade
performance in their respective applications. so, how do you
know which one to use? As always, select the oil that lists
the specification recommended by the vehicle manufacturer
and be confident that the vehicle's engine and emissions system
are protected. Published, AMSOIL Magazine 11/12.
AMSOIL Signature Series
Synthetic Motor Oil
AMSOIL Signature Series Synthetic
Motor Oils are formulated to meet the latest API SN Resource
Conserving and ILSAC GF-5 industry specifications. AMSOIL
Signature Series Oils include 0W-20, 0W-30, 5W-30 and 10W-30
and represent the very best motor oils AMSOIL has to offer,
allowing motorists to take advantage of maximum extended
drain intervals. AMSOIL Signature Series Synthetic Motor
Oils are recommended for drain intervals of up to 25,000
miles/one year, whichever comes first (15,000 miles/one
year in severe service conditions).

Synthetic Motor Oils offer the longest drain intervals
on the market, unsurpassed protection and performance that
effectively extends equipment life and improved fuel economy,
saving customers money at the pump and reducing the nation's
dependence on foreign oil.

synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
NOACK Volatility Test
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
