New Proposal for Asset Preservation and Parts Shortage in Classic and High-Mileage Cars! 'SOD-1 CLASSIC' Oil Additive Released June 1, 2026

Since its launch in 1998, it has been chosen by maintenance professionals with over 4 million cumulative applications. D1 Chemical Co., Ltd. (Headquarters: Fukuoka Prefecture), the maker of the versatile oil additive 'SOD-1Plus,' released 'SOD-1 CLASSIC,' a high-viscosity oil additive specialized for classic and high-mileage cars, on June 1, 2026. Classic and high-mileage cars have different design philosophies compared to modern vehicles. As years of use and mileage increase, lubrication conditions differ significantly from when they were new. SOD-1 CLASSIC uses a high-viscosity ester base to improve oil film retention when added to multi-grade oil, supporting the protection of valuable vehicles by supplementing viscosity and oil film thickness. With its three functions of 'Cleaning, Protection, and Recovery,' it improves the internal environment of the machine while strengthening the oil in each part. It is simple to use: just add the specified amount to the oil volume during a regular oil change. Add 10% of the total oil volume for engines, MT, diff/transfer, and power steering, and 7% for AT. It is compatible with all standards and viscosity grades of fully synthetic, semi-synthetic, and mineral oils.
