Medium Speed Trunk Piston Engine Oils
​ ​

SINOPEC medium speed trunk piston engine oils are blended from highly refined base oils and multifunctional additive packages. They can be used in medium speed four stroke trunk piston engines and crankcases or power plants running on high sulfur content fuels.

 

 


Features and Benefits

    ·  Higher acid neutralization property, releasing the corrosion of acid  materials produced in the combusting process of poor fuels effectively, cleaning piston and engine

    ·  Excellent emulsifying resistance

    ·  Good oxidation resistance and anticorrosion performance to inhibit the formation of oxides

Recommended Applications

    ·  Suitable for the lubrication of medium speed trunk piston marine engines and stationary diesel electric generators burning high sulfur content or heavy diesel fuels

    ·  Suitable for different TBN (Total Base Number) products according to the sulfur content of fuels
