Kubota SAE 10W-30 Engine Oil 1 Gallon — Synthetic-Blend for Compact Tractors & RTVs, API CK-4/CJ-4

Kubota SAE 10W-30 Engine Oil (1 gallon) is a factory-formulated lubricant engineered for Kubota compact tractors, UTVs and zero-turn mowers to help maintain engine cleanliness and reliable performance under mixed operating conditions.

This full-synthetic-blend engine oil, part number 70000-10201, meets multiple API service categories and is tuned for the demands of small diesel and gasoline engines found in Kubota B, G/GR/T/TG, RTV and Z series equipment. It helps manage oxidation and viscosity stability so engines run smoothly across variable loads and temperatures. The one-gallon package is convenient for on-site top-ups and scheduled service intervals, matching the capacities of many compact work machines.

How does this oil support engine durability?

The formula provides enhanced oxidation control and shear stability, which reduces oil breakdown during heavy or prolonged use. By preserving viscosity and minimizing deposits, it helps components like pistons and bearings operate with less wear over time.

• API CK-4, CJ-4, CI-4 Plus, CI-4, CH-4 performance levels
• Designed to resist thermal and mechanical thinning
