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
Perfect anti-emulsification and water separation properties.
Outstanding oxidation stability to control the oxidation products effectively.
Excellent detergency and dispersancy to assure the cleanness of piston and other parts.
Superior cylinder ring and liner wear protection.
Effectively neutralization of acid substances formed during burning of fuel.
Recommended Applications
Suitable for medium speed four stroke trunk piston engines and crankcases or power plants running on high sulfur content fuels.
T4030 can be used for engines running fuels with sulfur content less than 4.0% by weight.
Also can be used to lubricate diesel-driven dynamotors.
