The Types segment classifies lubricants by functional chemistry: Hydraulic Oil, Gear Oil, Engine Oil, Transmission Fluid, and Coolant Additive. Hydraulic oil, typically ISO VG 32‑46, represents the core volume due to its role in power‑train actuation across all equipment classes, contributing approximately 35 % of market value. Gear oil, formulated with EP additives and high viscosity indices, supports planetary and final drive gear sets, accounting for around 25 % of sales. Engine oil, engineered for high‑temperature stability and soot control, captures roughly 20 % of the market, reflecting the prevalence of diesel engines in off‑highway fleets. Transmission fluid, a hybrid of hydraulic and gear characteristics, supplies about 12 % of revenue, primarily in articulated dump trucks and wheel loaders. Coolant additives, which enhance heat‑transfer efficiency and corrosion protection, occupy the remaining 8 %. This type‑based taxonomy clarifies how each lubricant class underpins specific performance requirements and collectively determines the market’s aggregate size.
