Comprehensive Engine Protection
Advanced additive technology complements the properties of the base oil and provides the performance characteristics required of the finished lubricant.
The additive system provides wear protection, deposit control, friction reduction, and oxidation stability. Modern YOKOHAMA OIL formulations also focus on turbocharged engine protection, LSPI prevention, timing chain wear protection, and engine cleanliness.
