    • Nugraha KartasasmitaVice Chairman - Indonesian Lube Society (MASPI)
    • Fundamental Drivers of Lubricant Quality1. TECHNOLOGY – ENVIRONMENTAL – FUEL ECONOMY DEMAND2. FUEL TREND DEMAND
    • Technology Environmental – Fuel EconomyEnvironmental End User Demand OEM Respons Lubricant ResponsDemand• Emission • Reduce burden of • Engine/Equip- • Higher Quality Legislation Ownership ment Changes • Extended Drain• Corporate • Extended drain • Exhaust After Average Treatment Treatment• Fuel Economy • Higher reliability • Exhaust After • Device Standard • Lower Operation Treatment Device Compatibility • Lower Life Time • Improved Fuel • Fuel Economy Cost Efficiency
    • Future Lubricant Engine: Higher speed Higher efficiency Higher operating temperature Lower emission Compatibility to renewable fuel Lubricant : Lower viscosity Higher oxidation stability Higher viscosity index Compatibility to renewable fuel
    • Lubricant Improvement
    • Implication for LubricantProduct Continuous up-gradation of lubricant quality levels: SAE 15W40 / 10W30 / 10W40 / 5W40 / 0W30 / 0W20 Group II / III / IV/V base stocks
    • 2. FUEL TREND DEMAND
    • Bio-Fuel = Future Fuel Source: Product form: Vegetable Oils ester (Fatty Acid Methyl Animal Fats Esther FAME) Process: Trans glycerin Esterification FAME blended with Using Alcohol Diesel Fuel at: (Methanol/Ethanol) 5% (B5), 10% (B10), 20% (B20)
    • Bio-Fuel = Future Fuel Europe: Rape seed methyl ester Typically B05 United State (US): Soy bean methyl ester Bio-diesel typically B20 Asia Pacific: Palm oil methyl ester Typically B05
    • Impact Bio-Fuel toLubricant Impact of bio-diesel on: engine cleanliness potential consequences of fuel dilution contamination of the engine oil Droplet characteristics + lower volatility + spray pattern + wall impingement non-combusted bio-diesel (past the piston rings) fuel dilution
    • Oxidation Unsaturated (particularly polyunsaturated fatty acid esters: derived from corn, olive and sunflower oils) exhibit poor oxidative stability Un burnt bio-diesel entering the oil sump oxidized lubricant degradation and thickening
    • Injector Fouling Free fatty acids + water increased corrosion of the injector system Presence of glycerol + viscous glycerides contribute injector coking Higher quantities of bio-diesel increase injector fouling (due to the thermo-oxidation and thermal polymerization properties of unsaturated bio-diesel) If injector tip deposits build up spray pattern disrupted piston deposits increase ring-sticking and increase fuel dilution
    • Wear and Corrosion High level of fuel dilution reduce the oil viscosity lower oil film thickness higher friction higher wear
    • Oil Quality Bio-diesel entering the oil sump may undergo oxidative polymerization severe sludge precipitation significant loss of dispersancy / antioxidancy increase in piston deposits ring- sticking
    • Conclusion Support Future Emission Regulation Lower viscosity Higher viscosity stability Higher oxidation stability Compatibility to Bio-Fuel Higher oxidation stability Higher viscosity stability Better dispersancy Better detergency Higher thermal stability
