A delicately blended mineral-based single-grade motor oil, crafted to meet the unique needs of classic cars and motorcycles lacking an oil filter or featuring a cyclone separator (disk filter). Carefully chosen base oils and additives ensure peak lubrication and excellent wear protection across diverse operating conditions. Specifically formulated for classic vehicles where an unblended or very mildly blended lubricant is mandated. Always refer to the operating instructions provided by the vehicle and engine manufacturers.
