Mobil passenger-vehicle-lube , 中国

Integrated Electric Motor / Reduction Gearbox Fluid

Product Description

Mobil EV Cool Drive MS 304 is tailored specifically for oil-cooling electric vehicle as well as hybrid vehicles, with superior friction performance for synchronizer system and clutches and provide outstanding anti-copper corrosion performance and materials compatibility.


Features and Benefits

1. High volume resistivity helps minimize the risk of electric short circuits and allows for direct contact with electrical components

2. Compatible with conductive and insulating materials

3. Extended fluid life through superior thermal-oxidative stability and outstanding resistance against sludge and deposit formation

4. Excellent corrosion protection and thermal-oxidative stability to maintain system cleanliness over equipment life

5. Provides excellent friction control, suitable for select clutch plate operated shift devices

6. Superior friction performance for synchronizer system and clutches



Advantages and Potential Benefits


Maintains excellent viscosity control over a wide range of temperatures, reducing viscous drag, which in turn helps vehicles go further between charges.


Helps prolong the life of your electrified vehicles, protecting components from wear, while helping prevent your electric motor from overheating. Helps extend the life of your gears/gearbox, bearings & electric motor.


Helps keep your vehicles and components running safely.



Mobil EV Cool Drive MS 304 is designed for use in electric vehicle reduction gearboxes with and without integrated electric motor, balancing lubrication performance with cooling properties for electric components.
