Gomes Presents at the AEA VI International Symposium on Lubricants, Fluids and Additives

Ricardo Gomes, technical service manager for the Central and South America region at Evonik Oil Additives, is presenting a paper titled “The Influence of Viscosity Index Improver Type on the Viscosities of Motorcycle Engine Oils Targeting Improved Fuel Economy” at the Brazilian Association of Automotive Engineering’s VI International Symposium on Lubricants, Fluids and Additives.

“Through blend studies of SAE viscosity grades commonly used in 4T motorcycle engines, we have observed differences in low-temperature fluid viscosity for different types of viscosity index improvers (VIIs),” said Mr. Gomes. “There are significant advantages in using polyalkyl methacrylate (PAMA) VIIs and novel comb VIIs in 4T motorcycle engine oils targeted or evaluated for fuel economy.”

Mr. Gomes is presenting his paper at the Symposium on October 24 at 3:10 p.m. at Villa Noah in São Paolo, Brazil.

About Evonik Oil Additives

Evonik Oil Additives has taken a leadership role in developing lubricant additive technology designed to improve fuel efficiency and productivity. Energy saving results have been demonstrated with VISCOPLEX® Viscosity Index Improvers (VIIs) in engine oils, driveline fluids and gear oils. Industrial and off-highway equipment field tests have also recorded up to double-digit improvements in fuel savings with DYNAVIS® technology for hydraulic fluids, reducing operating costs as well as CO2 emissions. Evonik’s VISCOBASE® technology offers an ideal balance between a very shear-stable VII and a synthetic base fluid, providing excellent solvency in automotive gear oil formulations such as heavy duty axle oils and manual transmission fluids. In all of its many applications, Evonik Oil Additives strives for Resource Efficiency.

Formerly known as RohMax, the Evonik Oil Additives business line of Evonik Industries also specializes in high-performance additives and technologies for fuels and refinery products. Evonik’s VISCOPLEX® Cold Flow Improvers (CFIs) provide outstanding flow properties for biofuels in any region or season. VISCOPLEX® dewaxing aids (DWAs) are designed for refinery solvent dewaxing processes that involve differing lube oil viscosity grades, especially bright stocks.

Advanced regional technology centers, modern global manufacturing centers, and a secure and reliable supply chain worldwide enable Evonik’s continuous development of customized solutions for customers anywhere on earth.
