Biodiesel produced from triglyceride which is main component of animal fats and vegetable oils by methanolysis was known for excellent lubricity. In this study, the lubricity of 12 kinds of biodiesel come from vegetable oils were analyzed using HFRR (High frequency reciprocating rig). The biodiesel synthesized from soybean oil has best lubricity by 153 ㎛ of wear scar in HFRR and used fried oil's biodiesel has slightly low lubricity by 299 ㎛. Also we have found that the lubricity of diesel was improved when mixing ratio of soybean biodiesel was increased in base diesel.

Biodiesel was well known for eco-friendly alternative fuel for petrodiesel. But biodiesel have disadvantage such like it was derived from food resource which was high price. In this study, We synthesized the biodiesel from duck's oil which was food trash via transesterification under base catalyst. After analytic result of density, kinematic viscosity, cold temperature characteristics, lubricity and cetane number which were main fuel characteristics, this duck's biodiesel have enough to fuel specification for except of domestic winter season.

GTL(gas-to-liquid) fuel produced by the Fischer-Tropsch process using carbon monoxide(CO) and hydrogen(H₂) is expected to be one of the environmental friendly fuel for alternative and blended to petrodiesel. But GTL have poor lubricity due to paraffin as main component of GTL which is not involve polar materials. In this paper, we had investigated the lubricity improvement of GTL fuels with various lubricants using HFRR(high frequency reciprocating rig).
