Champion 4000 ULTRA is our high-efficiency, all-weather synthetic transmission/hydraulic fluid designed for tractors, diggers, excavators and vocational equipment. Our synthetic hydrocarbon base oils and exceptionally shear-stable technology results in a fluid with optimal fluid life, cold flow, and viscosity control. Compounded with premium additives, 4000 ULTRA provides excellent anti-wear, extreme-pressure, friction control, cleanliness, anti-oxidant, anti-corrosion, and air release properties. Excellent cold-flow reduces start-up wear Shear stability and viscosity control reduce internal pump leakage Dispersants and anti-oxidants clean and control sludge and varnish Friction modifiers provide excellent resistance to noise, chatter, and slippage Extreme-pressure additive protects against scuffing and spalling of gears Seal conditioners prevent sloughing, blistering, cracking and hardening of gaskets Synthetic hydrocarbon base oil resists thermal and oxidative breakdown and releases water better than conventional base oils. Retains a better high temperature film strength than competing monograde and HV-type fluids. Champion 4000 ULTRA reduces loss of power due to internal pump-leakage in hydraulic systems. This results in typically 5 - 10% reduction in fuel or energy consumption. By reducing your usage of fuel and electricity, you can save money and provide the best protection for your equipment. Champion 4000 ULTRA meets both summer and winter grade John Deere specs J20C and J20D as well as J20D/CNH MAT 3526 winter specifications. 4000 ULTRA also meets specs of most major tractor and equipment manufacturers for transmission/hydraulic oil. It also meets the Parker Hannifin HF-0 pump specification. Part# 4001U 2/2.5 Gal. Part# 4001AN 55 Gal
