SINOPEC Crosshead Diesel Cylinder Oils are blended from highly refined base oils and multifunctional additive packages. They can be used in crosshead engines running on high sulfur content diesel or residual fuels.
Features and Benefits
· Excellent capability to neutralize acid substances producing in combusting of fuels, protecting engine from acid corrosion
· Good antiwear performance to extend engine life
· Good detergency and dispersancy to prevent pistons from carbon deposits
· Good diffusivity performance to drive oil quickly reaching and spreading out over the steel surface to form oil films.
Recommended Applications
· Suitable for low speed cylinder of cross-head marine diesel engines
· Use different TBN (Total Base Number) products according to the sulfur content of fuels
