Dollar General Steps up to API SN/ILSAC GF-5
July 10, 2017
CLICK BOTTLE FOR DETAILS
As widely reported by PQIA and many local and national news outlets, including an ABC News – Good Morning America segment, the discount chain Dollar General is facing multiple lawsuits for selling “Obsolete” motor oil. The most recent of these lawsuits was filed last month by New Mexico’s Attorney General, Hector Balderas. The lawsuit alleges false advertising, unfair trade practices, and environmental public nuisance for the sale of obsolete motor oil in New Mexico stores from 2010 until February of this year.
Regardless of how the lawsuits are settled, there is some good news to report regarding the Dollar General (DG) branded motor oils. The PQIA has recently observed, from a relatively limited sampling of Dollar
General stores, that the company has upgraded its store brand (DG Auto) motor oils to the current API
SN/ILSAC GF-5 service category. The PQIA applauds Dollar General for making the change, and we remain hopeful that this CLICK BOTTLE FOR DETAILSaction has been implemented at all of its stores.
The PQIA recently purchased two samples (5W-30 and 10W-30) of the DG Auto brand motor oil label as meeting the API SN/GF-5 Service Category. The results of the tests conducted on the samples show that the products tested meet the SAE J300 specifications for the SAE Viscosity Grades shown on the labels and are consistent with the current API SN Service Category and ILSAC GF-5.
The results are in on four samples of 5W-20 motor oils. Although the results of the tests conducted on the samples meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and are consistent with the listed API Service Categories, one of the brands (Zecol-MAX) got our attention. This is because while the front label on the sample tested identifies the product as a "Synthetic SAE 5W-20 Motor Oil," the back label identifies it as a "Semi-Synthetic SAE 5W-20 Motor Oil." Once again, consumers are advised to read the labels when buying motor oils.

PQIA Releases National Survey Findings on ATF
June 21, 2017
METUCHEN, NJ - June 21, 2017 - The Petroleum Quality Institute of America (PQIA) today announced the findings of a national survey (Automatic Transmission Fluid - Survey 2017) focused on the quality and integrity of automatic transmission fluid (ATF) in the US market.
According to Thomas F. Glenn, President of PQIA, "The findings of the survey are eye-opening. They show that the lubricant industry and consumers recognize there are significant issues around quality and integrity of automatic transmission fluid in the US market and that action can and should be taken to address them."
Key findings from PQIA's survey reveal that off-spec, potentially transmission damaging ATFs are a significant issue in the minds of buyers and sellers of ATF, and misleading ATF labeling is the leading reason why. With that, Glenn says," The survey reveals an interesting dichotomy between the high levels of concern around labeling but a fairly low concern about actual quality. This suggests that if the industry can get labeling in order, there may not necessarily be significant issues with the quality of ATF in the market."
The Most Concerning Issues About ATFs in the Market
For those unfamiliar with ATF, it's a vital lubricant that performs many functions enabling a transmission to operate. Without ATF, nearly all cars on the road would come to a halt. But
as critical as ATF is to the proper operation of a vehicle, the PQIA survey reveals there is considerable confusion among buyers and sellers of ATF about the products in the market. This is because where Dexron® III/Mercon® fluids used to be the leading types of automatic transmission fluids (ATF) in the US market, these ATFs are being replaced by a splintering number of newer OEM specific ATF requirements, including ATF+4, Mercon V, Mercon LV, Dexron VI, ATF DW-1, ATF T-IV, SP-IV, Matic S and Matic D and K, Toyota ATF-WS, Honda DW (ZF), Diamond SP-IV, and others.
What used to be a fairly simple matter of selecting the right ATF for your car has become much more complicated. For these reasons, and others identified in PQIA's survey, the industry can and should do more to protect the interests of consumers, installers, and others buying and selling automatic transmission fluid. And from what the survey reveals, a good start is in educating buyers and sellers, and improving the labeling of ATFs in the market.

PQIA's Thoughts on the
AAA's Synthetic Motor
Oil Report
The American Automobile
Association (AAA)
released a comprehensiveresearch
report announcing
that "synthetic oil
outperformed
conventional oil by an
average of nearly 50
percent in its
independent evaluation,
offering vehicles
significantly better
engine protection for
only $5 more per month
when following a
factory-recommended oil
change schedule."
The Petroleum
Quality Institute of
America applauds AAA's
efforts to help educate
consumers about motor
oils and found their
report to be very
interesting and
informative.
While PQIA
believes most would
agree that full
synthetics do provide a
higher level of engine
protection than
conventional motor oil,
and there is bench and
engine test data to
support such claims, the
devil is in the
details. And although
such details as the
brands tested, why they
were selected, and how
the AAA defines
"premium" among the
brands tested are not
made available in the
research report, these
are important factors to
consider. This is
particularly the case
with regards to the
definition of "premium"
since a number of motor
oil manufacturers now
offer three tiers of
synthetic motor oils,
including synthetics,
high mileage synthetics,
and synthetics offering
significant extensions
in oil change
intervals.
Further, PQIA
feels it is important to
note the following with
regards to the eight
industry-standard ASTM
(American Society for
Testing and Materials)
tests the AAA used to
evaluate the quality of
synthetics and
conventional engine
oils:
Some of the tests
in the study are highly
variable (i.e. MHT-4, 1
sigma can be as high as
15 units) and may not be
included in the upcoming
ILSAC GF-6
specification.
The TFOUT is not
an industry accepted
test because it does not
predict field
performance as opposed
to liking certain
chemistries. The test
has not been used as
part of ILSAC
Specifications which
began in the early
1990's.
The value of KO
Shear on a 5W-20 is
minimal since oils are
formulated at the top of
specification and rarely
shear out of grade, and
are typically
significantly above
minimum. Directionally,
however, a full
synthetic motor oil
would outperform a
conventional.
The TEOST 33
provides limited
information to support
claims about synthetics
out performing
conventional motor oils.
The Brookfield
test yields minimally
valued insights in the
performance differences
between synthetic and
conventional.
Another
important point for
consumers to consider is
that the AAA report
says "synthetic oil
outperformed conventional
oil by an average of nearly
50 percent in its
independent evaluation,
offering vehicles
significantly better engine
protection for only $5 more
per month when following a
factory-recommended oil
change schedule." PQIA
advises consumers that a key
part of this statement is "when
following a
factory-recommended oil
change schedule."
As such, it does not say
synthetic motor oils can
last 50% longer.
Again, PQIA applauds the AAA
for its efforts to
help educate consumers about
motor oils, and PQIA
understands there is bench
and engine test data to
support the advantages of
synthetics over conventional
motor oil.

A Look at the 0W-20s Examined by PQIA in 2014 to 2017(YTD)
April 11, 2017
Although SAE 5W-30 accounts for the majority of the passenger car motor oil (PCMO) consumed in the US, demand for the grade continues to decline as some of the leading Original Equipment Manufacturers (OEMs) shift to lower viscosity grade PCMOs in an effort to improve fuel economy. The biggest beneficiary of the shift is SAE 0W-20. Currently accounting for roughly 10% of PCMO consumed in the US, demand for the 0W-20 viscosity grade is expected to nearly triple over the next 10 years. Because of this, the PQIA will be examining an increasing number of 0W-20s moving forward as more of these products populate retail shelves.

The results of the tests conducted on this sample do NOT meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and are NOT consistent with the listed API Service Category.
The Kinematic Viscosity @ 100°C is 14% lower than the minimum viscosity specification for this SAE grade. In addition, the Volatility result is substantially higher than the maximum allowed in the SN specification.
It should also be noted that the back label states this product "is compatible with SN, SM, SL and ILSAC GF-5 service classification." when in fact it does not meet any of these specifications.
Use of this product in the majority of vehicles on the road today may cause unsatisfactory engine performance.

SuperS Custom Plus SAE 5W-20 SJ
Advisory: The results of the tests conducted on this sample meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and are consistent with the API SJ Service Category. It should be noted, however, that API SJ motor oils are intended for use in vehicles built prior to 2002. Although not stated on the labels, consumers should be aware of its limited use. Further, whereas the labels state, "For use where an SJ motor oil is recommended," and "is compatible with API approved engine oils," the labels do not claim this product actually meets any API Service Categories.

FEBRUARY 6, 2017
PQIA examines five more motor oil samples purchased in the midwest and issues a Consumer Alert on one and an Advisory on another. Cautions consumer not to Buy SUPER XXX Platinum 10W30.
Consumer Alert: A Consumer Alert is issued on SUPER XXX Platinum “10W30 API SM/GF-3” manufactured by Chi-Town Lubricants located in Dolton, IL. The results of the tests conducted on the sample DO NOT meet the SAE J300 specifications for an SAE 10W-30 viscosity grade, and ARE NOT consistent with the referenced API SM Service Category. Use of this product in automobile engines may cause harm to most vehicles currently on the road.
CLICK FOR DETAILS
Advisory: An Advisory is issued on PolyGUARD All Season 5W-30 API SF/CC manufactured in PolyGuard Products Division located in Medina, MN. The reason for the Advisory is that the product is labeled as meeting an OBSOLETE API Service Category (SF/CC) and the labels fail to give consumers adequate warning about its potential harm to more modern engines. With regards to the API SF Service Category, the API states: “CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1988. May not provide adequate protection against build-up of engine sludge.”

PQIA Issues Consumer Alerts on Two AntiFreeze/Coolant Samples
JANUARY 27, 2017
Two of the five coolant/antifreeze samples recently examined by PQIA fail to meet their label claims for freeze point protection.
Polar Zone: Test results on the sample of Polar Zone examined has a freeze point of -2.2°F. This freeze point is above the labeled claim stating “Protects to -20°F,” and well above the industry standard of -33.5°F. In addition, the pH at 12.12 is 1.12 higher than required to meet the ASTM D-3306 specification.
Super XXX: The freeze point of the product tested is -15°F. This is higher than the product’s labeled claim of -34°F and is higher than the industry standard of -33.5°F. The test results are not consistent with a new coolant based on the standard specifications stated in ASTM D-3306 and ASTM D-4985. The level of degradation acids (glycolate and formate) in the sample tested are unusually high. In addition, the concentration of chloride is 228% higher than the maximum level of 25mg/L as stated in ASTM D-3306 and ASTM D-4985 for a new coolant.
Antifreeze/coolants recently tested by PQIA that are consistent with the labeled claims:
Note: Major Brands Oil Company contacted PQIA saying that the results of the tests conducted on its product in 2015 were not reflective of the company’s current quality and encouraged PQIA to proactively test its Performance Antifreeze & Coolant currently in the market. PQIA did so and purchased products from two locations in Michigan. Click Performance jugs above for test results on the samples.
Smitty’s Supply to Pay $755,155 in Consumer Protection Settlement
JANUARY 27, 2017
The Orange County District Attorney’s Office has obtained a consumer protection settlement against a Louisiana Company, Smitty’s Supply, Inc.
Based on random product testing conducted by the California Department of Food and Agriculture (CDFA), Division of Measurement Standards (DMS) that began in 2012, it was determined that samples of Smitty’s Custom Plus™ Motor Oil products sold within the State of California “did not meet the specifications represented on the label.”
The Final Judgement states that “There were several violations for selling, or offering for sale, petroleum or automotive products of a different grade than represented on the label and adulterated or mislabeled product that does not meet the latest automotive manufacturer’s recommended requirements as indicated on the label.”
The total settlement was in the amount of $751,155. This includes civil penalties of $555,000, investigative and other costs of $196,155.
In addition to the $751,155, the Final Judgment and Permanent Injunction requires Smitty’s to develop and implement a quality assurance program to ensure that the lubricants it sells or distributes in the state of California comply with industry standards and all state and federal laws. The QA program must also include that Smitty’s places a traceable date and batch number of every product to assure that the quantity and location of products sold or distributed in California can be traced.
Importantly, the quality assurance program must also be maintained in writing and explained to Smitty’s employees involved in the management, blending, testing, packaging, transportation and others involved with its lubricant products. Further, they must acknowledge, by signature, that they will abide by the QA program requirements.
PQIA examines five samples of automatic transmission fluid purchased in the Midwest market. While the results of the tests conducted on three of the samples meet the requirements for their labeled claims, PQIA issues Consumer Alerts/Don’t Buys on two. The two samples are branded under names all too familiar to PQIA. One is the Everclear brand ATF. This is the fourteenth time PQIA has issued Consumer Alerts on lubricants marketed under the Everclear brand. Further, this product has been ordered off the shelves in the states of Georgia and North Carolina.
