Savant Labs Expand Testing Capabilities in Electric Vehicle Lubricants and Fluids
Savant Labs, an independent testing laboratory and research center, announced the expansion of its hybrid and electric vehicle (HEV and EV) testing capabilities for lubricating oils, fluids, and greases. The evolution of fully electric and hybrid transportation continues to evolve, and the same is true with the test methods and equipment for those critical areas of interest.
Many EV components are made from materials not typical in an internal combustion engine (ICE) vehicle and there are different material compatibility requirements for EV fluids. In addition, the EV powertrain has fewer moving parts and operates under conditions that are, in many ways, different than those of ICE vehicles. The fluid performance characteristics of electrical conductivity, thermal transfer, copper corrosion protection, and elastomer compatibility are key considerations. Developing and testing lubricants and fluids engineered to meet the specific requirements for electric vehicles are critical to providing protection and assurance.
Of concern are corrosion, deposits, and conductive deposits. Different EV drivetrain fluid formulations may have inherently varying corrosion rates producing
conducting layer deposits in both solution and vapor phases. Conductive deposits form from the chemical reaction of the lubricating fluid and the copper at elevated temperatures under low voltage electrified conditions both in the fluid and at the vapor state.
The Wire Corrosion Test (WCT), originally developed by Lubrizol, is a new test offered by Savant Labs. In agreement with Lubrizol, Savant Labs are the sole source for this testing service in North America.
In addition, Conductive Deposit Test (CDT), equipment developed by Tannas
Co.is now also available.

ATIEL releases Code of Practice issue 22
ATIEL, the technical association of the European lubricants industry, has released Issue 22 of its Code of Practice, that provides guidelines for the development of engine oils that meet the latest European ACEA specifications.
As of 25 October 2021, Issue 22 of the Code of Practice supersedes Issue 21. The latter, however, remains available on the ATIEL website, for valid claims against ACEA 2016 light duty sequences, until 30 April 2022. Issue 21 remains valid for ACEA Sequences 2016 for HD engine oil. Issue 22 considers the ACEA sequence 2021 for Light Duty engine oil. The main changes are: • the introduction of a new VGRA Guideline for the Toyota TCD test and worked examples. • clarification of some definitions.
• The rebranding of VGRA and BOI guidelines (with added examples) for enhanced clarity
The ATIEL Code of Practice (CoP)-in operation since 1996 – has been developed jointly by the European Automobile Manufacturers’ Association (ACEA), the Additives Technical Committee (ATC) and ATIEL. The purpose of this Code is to provide a mechanism and a basis for commitment to standardise practices when developing, marketing, or manufacturing engine lubricants for which compliance with the ACEA Oil Sequences is claimed.
