Getting Up to Speed on the New Passenger Car Motor Oil Specifications
Beginning on May 1, 2020, new performance specifications will start to appear on the labels of passenger car motor oil. The new specifications include International Lubricant Specification Advisory Committee (ILSAC) GF-6A, GF-6B, and the API SP. Motor oils meeting these specifications provide improvements over the previous in the areas of fuel economy and fuel economy retention, emission system compatibility, and wear protection.
Understanding PQIA’s reach in getting the word out about motor oil related issues, Phillips 66, a long-time supporter of PQIA, reached out to us suggesting we include its series of educational videos about GF-6 on the PQIA website.
Dr. Scott McQueen, Manager, Lubricants Research and Product Management for Phillips 66, says the videos were produced by Phillips 66 for installers and others in the field needing a quick way to get their team up to speed on GF-6. To this, Dr. McQueen added, “We feel education is critical as it pertains to the oil standards and what they mean for our customers and end consumers. Significant technology goes into formulating engine oils that protect and maximize the performance of the engines OEMs are manufacturing today. As a supporter of PQIA, oil quality and correct licensing are important to Phillips 66 and our industry.”
PQIA encourages consumers to view the videos to learn more about the new passenger car motor oil specifications and what they mean. Because motor oils are not all the same, and using the wrong motor oil in a vehicle can void its warranty and potentially cause harm, it’s crucial to be up to speed on API specifications.

Buying Motor Oil Online
While this is a very efficient and easy way to shop, the Petroleum Quality Institute of America advises consumers to take the time to look for the specifications the product meets when buying motor oil online. If not shown on the first screen, click or scroll for more details before adding motor oil to your cart.
Read the Labels on Motor Oil Before You Buy
Know how to read the labels and what to look for on both the front and back labels of the motor oil you buy, or you may be using product that can cause unsatisfactory performance or damage to your engine. The following are some key items to look for on motor oil labels and to consider before buying.

Tractor Hydraulic Fluid Labeling
In July of last year, the National Conference on Weights and Measures (NCWM) voted on, and passed amendments to NIST Handbook 130 (HB-130). Among the approved changes, was amended language to both the Uniform Regulation for the Method of Sale of Commodities and the Uniform Fuels and Automotive Lubricants Regulation sections on Tractor Hydraulic Fluid (THF).
SN PLUS Motor Oils – Calcium Down, Magnesium Up
The SN PLUS Service Category was introduced as a supplement to API SN specification in 2018 to mitigate low speed pre-ignition (LSPI) events in Turbocharged Gasoline Direct Injection (TGDI) engines. Such LSPI events can cause engine knocking, decreased efficiency, and in the worst case, catastrophic failure due to cracked pistons.
Playing Roulette with 303 Yellow Buckets
There has been a significant amount of talk about “303” tractor hydraulic fluid (THF) over the past year, and for good reason. This is because although THFs labeled as 303 have commonly been seen in the market for decades, and for some considered the product of choice due to price, three states (including Missouri, Georgia, and most recently North Carolina), have issued stop-sale orders for tractor hydraulic fluid labeled, claimed or implied as meeting THF 303.
