Evonik Oil Additives’ Dr. Michael Webb Presents Paper at STLE Annual Meeting

Evonik Oil Additives’ Dr. Michael Webb, Technical Service Manager, will present a paper titled “Evaluation of ILSAC GF-5 Aged Oil Performance by ROBO Test” on Monday, May 6 at 1:30 p.m. at the Society of Tribologists and Lubrication Engineers (STLE) 68th Annual Meeting and Exhibition at the Detroit Marriott in the Renaissance Center in Detroit, Michigan.

The presentation will explain how the Romaszewski Oil Bench Oxidation (ROBO) test (ASTM D7528) was developed by Evonik Oil Additives and adopted in ILSAC GF-5 specifications as a test equivalent to the Sequence IIIGA. The ROBO test allows oils to oxidize quickly and cost- effectively and evaluates a broad range of passenger car gasoline engine oil formulations with various base stocks, viscosity modifier chemistries and performance packages.

“The development of the ROBO test is just one of the many ways Evonik Oil Additives keeps up with the demand for improved viscosity of in- service or aged oils. Evonik’s VISCOPLEX® Pour Point Depressants (PPDs) continue to overcome severe low-temperature viscometric demands of modern lubricants and enhance the value of formulations,” said Dr. Webb.

Evonik Oil Additives is a Gold-Level sponsor of the STLE welcoming party on Monday, May 6 at 6:30 p.m., and its technical specialists will be available at stand #513 during the exhibition on May 5-9. The display will include the Evonik Lotus Exige racecar loaded with a range of Evonik technologies as well as a racecar-driving simulator.
