Esso Standard announced Uniflo motor oil in a National Petroleum News report, pitching it as a high viscosity index product meeting API service classifications ML, MM, MS, and DG. The company claims the single-grade oil covers SAE 5W, 10W, 20W, and 20 requirements, reducing friction wear by up to forty percent while cutting corrosion and combustion chamber deposits. Esso also notes it eases cold weather battery drain because its viscosity rises from 315 to 725 Saybolt seconds as temperature drops from 70 °F to 40 °F.
