“…Generally, vegetable oil contains long chains of carbon atoms connected with open ended fatty acid chains which acts as the good friction modifier additives [7]. Most commonly used vegetable oils are derived from coconut, rapeseed, jatropha, sunflower, rice bran, rubber seeds, palm, canola, soybean, castor, and many other being tested for the potential use of lubricants [8]. The vegetable oil like pongamia and jatropha was mixed with mineral oil (SAE20W40) with the two different ratios 15% and 30% (% by volume), and it was found that the 15% blend had better tribological properties than the conventional lubricants [9].…”

Vegetable oil becomes a viable alternative to mineral or synthetic oils due to its biodegradable nature. In this work, one such vegetable-based non-edible oil (kapok oil) is blended with a mineral-based oil (SAE20W40) at 15 and 30% ratio (by volume), and its changes in thermal, tribological, and corrosive properties were evaluated. Four-ball tribometer is utilized to assess its dynamic friction coefficient and the wear scar diameter of the worn out area on the ball. Biodegradability and toxicity test of kapok oil were examined and compared with the palm and mineral oil through bacterial growth and brine shrimp assay methods, respectively. The results showed that the dynamic friction coefficient and specific wear rate of the blended oil were lesser than the mineral oil. The mineral oil produced a higher roughness average (R a) value than that of the blended oil. Kapok oil shows an adequate tribological properties (anti-friction and anti-wear) in contrast to the other vegetable oils. Overall, kapok oil had a high biodegradability nature and lower toxicity than the mineral oil.

“…The pungency of mustard oil is due to the presence of allyl isothiocyanate, an activator of the TRPA1 channel (Transient receptor potential cation channel, subfamily A) in sensory neurons. The viscosity index of Mustard oil is 205 [33] where as SAE20W40 lubricant [34], Sunflower oil [35], Rapeseed oil [36], Jatropha oil [37], Rice bran oil [38], Rubber seed oil [39], Palm oil [40], Millettia Pinnata oil [41], Coconut oil [42] has the viscosity index of 142, 176, 180, 205, 169, 182, 186, 169, 159, respectively. Generally, the Mustard oil has the average thermal conductivity of 0.166-0.171W/mK at 20°C, 0.169-174 W/mK at 60°C and the average dynamic viscosity of 93.9 mPa.s at 20°C, 20.989 mPa.s at 60°C [43].…”

“…The chemico-physical and thermo-physical distinctiveness and of rice bran oil are significantly higher than other vegetable oils and SAE20W40 (commercial lubricant mineral oil) [38]. However, the Mustard oil exposed superior wear resistance than coconut oil [44]. The chemicophysical and thermo-physical distinctiveness of the Mustard oil may be enhanced by homogeneously dispersing the carbon nanotubes (CNT).…”

Nowadays, environmentally friendly lubricants are developed to meet the standards of biodegradability, toxicity and bioaccumulation potential that reduce the adverse consequences to the aquatic atmosphere compared to conventional mineral based lubricants. In this study, an attempt made to enhance the feasibility of utilizing the Mustard oil as a commercial lubricating agent by homogeneously dispersing MWCNTs as an additive. The average crystallite size, surface morphology and elements of MWCNT are characterized through XRD, SEM, EDS and FTIR techniques, respectively. The surface deformation rate of matrix material (Mg) lubricated by Mustard oil and different weight fractions of MWCNT-Mustard oil nanofluid are estimated through Nanoindentation technique. The hardness, Young's modulus and AFM topography of the interacting surface infers that the dispersed MWCNT significantly enhance the lubricating properties of Mustard oil through micro-chipping and micro-softening effect.

Vegetable oils are promoted as a base oil for automobile lubricants due to increased concerns about the environmental damage caused by synthetic and mineral oils‐derived lubricants. Coconut oil exhibits excellent tribological properties but poor cold flow properties. This work investigates the effect of the addition of palm oil methyl ester (POME), obtained from the transesterification of palm oil, on coconut oil by blending it in three proportions with varying volumes and evaluating for lubricant properties namely tribological properties, rheological properties, thermal properties, chemical properties and corrosion and oxidative stabilities. Fatty acid composition are evaluated for the base oil and the blends. The findings show that the addition of POME improves the base oil's pour point and reduces friction and wear. The corrosion test shows only slight tarnishing of copper strips, while the HOOT and chemical tests indicate appreciable resistance to oxidation. Therefore, this blended mixture has the potential to be a viable bio‐lubricant alternative to traditional mineral‐based oils.
