产品说明
KATMOTO STOU 15W-40 is a super tractor oil universal that lubricates the engine, transmission, hydraulics, final drives and oil-immersed (wet) brakes of agricultural and compact construction equipment with a single SAE 15W-40 fluid. It combines diesel/gasoline engine protection with EP gear protection, chatter-free wet-brake friction and hydraulic anti-wear performance, simplifying inventory while delivering reliable all-in-one protection.
主要性能特点
| All-in-one lubrication
one fluid for engine, transmission, hydraulics, final drives and wet brakes. |
Engine protection
diesel and gasoline engine wear, soot and deposit control. |
| EP gear protection
extreme-pressure performance for transmission and final-drive gears. |
无异响湿式刹车
optimised friction for quiet oil-immersed brake operation. |
| Hydraulic anti-wear
protects hydraulic pumps and valves under load. |
Inventory simplification
reduces the number of lubricants needed on-site. |
