“…Reeves et al [31] conduct research on the effect of fatty acid composition of the viscosity index contained in the avocado seed oil, canola oil, corn oil, olive oil, peanut oil, safflower oil, sesame oil and soy oil. The result showed that the fatty acid composition affects the viscosity grades, with the highest viscosity in peanut oil for 70.24 cP.…”

Abstract. Since long time ago, petroleum oil has been used as a lubricant in motor vehicles. But, the uses of lubricants petroleum can pollute the environment and disrupt marine ecosystems and terrestrial. On the other hand, the use of lubricants in the world in 2008 reached 46 million kiloliters/year and increased by 2% every year. The future prospect the uses of lubricant petroleum on the vehicle's engine is predicted to have a bad prospect. Thus began research to identify suitable materials to replace petroleum based lubricants. It can produce from vegetable oils and animals oils by chemical modification. But, bio-lubricant properties are easily damaged so we need more research to improve the shelf life of the bio-lubricant. The research must be done to improve the characteristics by adding a bio-lubricant additive.

Although many studies investigating the tribological performance of pure vegetable oils have been conducted, a better understanding of vegetable oil tribological performance at extreme conditions is still needed. Similarly, little work has been carried out to study the influence of the vegetable oils on the performance of a lubricant formed from a blend of vegetable oil and conventional mineral engine oil. This work presents the tribological performance of vegetable oils, and their blends with mineral oil, in a high temperature and contact pressure reciprocating contact. Palm and soybean based vegetable oils were mixed with a commercial mineral engine oil at a 1:1 ratio by volume. The conventional mineral oil was also tested to provide a benchmark. The pure palm oil exhibited lower friction than soybean oil, but for wear performance, this was reversed. The friction performance of the palm oil was competitive to that of the mineral engine oil. The mineral engine oil was far superior in wear resistance over both vegetable oils. When blended with mineral engine oil both vegetable oils demonstrated a reduction in coefficient of friction when compared to their pure oil states. An improvement in wear performance was observed for both a blend of palm oil and mineral engine oil (25% improvement) and that of soybean and mineral engine oil (27% improvement). This work shows that for palm oil and soybean oil, the performance of a blended oil is influenced by its vegetable oil component and that tribological characteristics of vegetable oils are dominant. That said, the significant limitation of these vegetable oils is their ability to provide a satisfactory level of wear resistance. It is suggested that any future work in this area should have a greater emphasis on the enhancement of wear resistance.

“…Vegetable oils containing a high percentage of oleic acid lead to low friction coefficients and wear levels. The explanation of the phenomenon is that the oleic acid forms a dense layer at the interface with the metallic material, with a protective role and reducing the contact with the asperities [10].…”

The purpose of this paper is a comparison between rapeseed oil and soybean oil, regarding their rheological and tribological properties. Tests were performed on a Brookfield viscometer with cone-plate geometry, having the following test parameters: test type -shear rate imposed, shear rate (100...2000 s -1 ), temperature values between 20 °C and 75 °C. In parallel, there were proceed tribological tests on a four ball machine, for three speeds (1200, 1500 and 1800 rpm). The results of the tests highlight the better rheologial and tribological behavior of the rapeseed oil, thus it could be recommended in tribological applications.
