Implication for Lubricant Product

Continuous up-gradation of lubricant quality levels:

SAE 15W40 / 10W30 / 10W40 / 5W40 / 0W30 / 0W20Group II / III / IV/V base stocks

Bio-Fuel = Future FuelSource:

Vegetable OilsAnimal Fats

Process: Trans EsterificationUsing Alcohol (Methanol/Ethanol)

Product form:ester (Fatty Acid Methyl Esther FAME)glycerin

FAME blended with Diesel Fuel at:5% (B5), 10% (B10), 20% (B20)

Page 10: 03   vice chairman of maspi, nugraha kartasasmita

Bio-Fuel = Future FuelEurope:

Rape seed methyl esterTypically B05

United State (US):Soy bean methyl esterBio-diesel typically B20

Asia Pacific:Palm oil methyl esterTypically B05

Impact Bio-Fuel to Lubricant

Impact of bio-diesel on:engine cleanliness potential consequences of fuel dilutioncontamination of the engine oil

Droplet characteristics + lower volatility + spray pattern + wall impingement non-combusted bio-diesel (past the piston rings) fuel dilution

Page 12: 03   vice chairman of maspi, nugraha kartasasmita

OxidationUnsaturated (particularly polyunsaturated fatty acid esters: derived from corn, olive and sunflower oils) exhibit poor oxidative stabilityUn burnt bio-diesel entering the oil sump oxidized lubricant degradation and thickening

Page 13: 03   vice chairman of maspi, nugraha kartasasmita

Injector FoulingFree fatty acids + water increased corrosion of the injector systemPresence of glycerol + viscous glycerides contribute injector cokingHigher 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

Page 15: 03   vice chairman of maspi, nugraha kartasasmita

Oil QualityBio-diesel entering the oil sump may undergo oxidative polymerization

severe sludge precipitation significant loss of dispersancy / antioxidancy increase in piston deposits ring-sticking
