The research is to investigate the extreme pressure and
anti-wear characteristics of bio-based lubricating oils and compares them to
the extreme pressure and anti-wear characteristics of PAO4 base oilI
have chosen onion, pumpkin, avocado, and karanja oils as bio-based lubricating
oils for this investigation. I adhere to ASTM D5783 and ASTM D4172 in this
investigation. I adhere to ASTM D5783 for extreme pressure qualities and ASTM
D4172 for anti-wear properties. The following are the weld points for the
various oils: 1554N for karanja, 1541N for avocado, 1553N for pumpkin, 1534N
for onion, and 1556N for PAO4 base oil. The bio-based oils' weld
points are somewhat lower than those of PAO4 base oil. The load wear
index values for the following oils are available: karanja oil (95.78N),
avocado oil (124N), pumpkin oil (89.82N), onion oil (105.35N), and PAO4
(94.24N). The bio oils' load wear index is comparable to that of PAO4
base oil. Onion and avocado oils have greater load wear indices than PAO4
base oil. The average wear scar diameter (AWSD) is used to calculate the
anti-wear property; the higher the AWSD, the more wear occurs. The average
width of the oil is 699.33 µm for karanja, 939 µm for avocado, 763 µm for
onion, 717 µm for pumpkin, and 607 µm for PAO4 base oil. The bio
oil's AWSD is higher than that of the PAO4 base oil.
