Medium Speed Trunk Piston Marine Engine Oil Additives
Advanced Protection for Heavy Fuel Oil (HFO) Operation in Marine Engines
It has excellent acid neutralization, cleaning and dispersing, anti-wear and anti-oxidation properties, strong anti-corrosion and anti-rust functions, and keeps the engine clean. It has excellent engine protection performance, which reduces the wear of the engine after long-term use.
The oil products with a viscosity of 30 and 40 and a base value of 12 are suitable for medium-quality fuels with an S content of less than 1.0%. 3015, 4015, and 4025 are suitable for heavy fuels with an S content of less than 2%, 3030 and 4030 are suitable for heavy fuels with an S content of less than 3%, and 4040 is suitable for heavy fuels with an S content of less than 3.5%.
Product Introduction
This high-performance lube oil additives marine package is engineered specifically for medium-speed trunk piston engines burning high-sulfur heavy fuel oil (HFO). Its calcium sulfonate and salicylate hybrid chemistry delivers unmatched acid neutralization, wear protection, and deposit control in saltwater-exposed environments where emulsification and corrosion are critical challenges.
Performance Advantages
- Heavy Fuel Oil (HFO) Acid Neutralization
Neutralizes sulfuric acid from high-sulfur fuels (≤5% S), reducing corrosive wear by 60% in ASTM D665 seawater corrosion tests.
- Saltwater Demulsibility
Superior water separation (ASTM D1401: <0.5% emulsion after 30 min) prevents sludge formation in contaminated crankcases.
- Anti-Polishing Protection
Reduces cylinder liner polishing by 45% via controlled ash (≤1.2%) to combat abrasive wear from HFO ash.
- Thermal Deposit Control
Limits piston crown carbon buildup by 55% vs. conventional additives (CEC L-101 at 300°C).
- Multi-Metal Corrosion Inhibition
Our advanced lube oil additives marine solution chelates vanadium/copper ions from HFO combustion, preventing exhaust valve corrosion and extending engine life in demanding marine environments.
