In this study new antioxidant compounds were prepared by (thiol-ene) click chemistry, where these compounds were prepared using (1:1) mole ratio of (thiol : eugenol) in the presence of benzoyl peroxide as initiator and the reaction is carried out at (100 0C) for (9) hrs. (FT-IR), (1HNMR), and mass spectroscopy were used to characterize the synthesized compounds. They were evaluated as antioxidants by adding compounds to base oil and lubricant oil, where they showed high antioxidant activity against lubricant oil oxidation processes.

“…The Society of Automotive Engineers (SAE) reported that there are many levels of properties and different sorts of lubricants. For instance, lubricants with synthetic grade are the excellent kind and can be produced from non-petroleum or petroleum compounds of the chemical elements [8]. Different standard tests are used to analyze lubricant condition in an engine oil system after remaining it for different length trips or before using, such as follows;…”

Fresh engine oils or engine lubricants lose some of their properties during service, engine lubricant deterioration leads to change in oil properties, which ultimately have effect on engine overall performance. Therefore, it is very important to characterize used engine lubricants at different using conditions to check the performance and ability of existing oils, which in turn protects engine parts and also designs new formulations to produce better type of engine oil or improve the existing oil. Therefore, optimizing engine oil lubricant changing time is very important for reducing environmental impact but renewing engine lubricant before it is due rises a customer’s cost. In this study, the most significant parameters such as kinematic viscosity, flash point and fire point were chosen to determine the changes and deterioration in engine oil properties. The oil samples were multigrade fully synthetic with SAE gradation 10W-30 grand ecodrive is used in 5 different passenger cars. Having information about these properties are crucial chemical and physical behaviours of engine oils and for keeping engine’s lifecycle. The test results of this work show that after 10,000 km, 10W-30 Delta NL motor oil brand (special synthetic with API SL) oil properties such as kinematic viscosity at cold start, 40 °C and 100 °C decreased 22.92%, 23.61% and 22.92% respectively. In addition, both flash point and fire point decreased 15.6% and 14.22% consecutively for the base properties, and according to the test results this type of engine oil is suitable to use for 10,000 km.

“…Corrosive acids, resins, and slugs are formed when the oil temperature increases (Owrang et al, 2004). Another function of oil in engines is to prevent corrosion (Sutar and Singare, 2018), for which purpose special anticorrosives are added to the oils. Sealing is used to prevent lubricants from leaking out of the engine, and therefore the oil that is used must also help to lubricate the seals without causing deterioration, shrinking, or hardening.…”

Engine oil or lubricating oil has a major effect on the engine life and the proper operation of any engine. Changing the engine oil before it is due increases a customer’s cost. The lubricating oil in every engine performs many functions such as reducing friction, preventing corrosion, protecting the engine against wear, removing all impurities, lubricating the moving parts, and cooling the engine parts. There are several causes for the deterioration of lubricating oil, including the properties of the oil, oil quality, and high engine temperatures. Consequently, the deteriorated oil must be replaced at a specified mileage or at specific time intervals to get the best engine performance. It is very important to know when to change the oil, because changing the oil too late can affect the engine parts and vehicle performance. However, replacing the oil too early influences the economy and environment and is an inefficient use of depleting resources. This study describes the kinematic viscosity, flash point, and fire point of multigrade Society of Automotive Engineers (SAE) 0W-20 Totachi (Totachi Industrial Co. Ltd., Japan) international brand oil, which has a 10,000 km guarantee and is approved by and used in 10 different vehicle brands, to determine the rate of deterioration of the parameters. These parameters are the most important physical behaviors of lubricating engine oils. Having information about these parameters is very important for maintaining an engine’s lifespan. The results of this study showed that after 10,000 km, the Totachi oil parameters such as the kinematic viscosity at cold start, at 40°C and at 100°C, the flash point, and the fire point decreased by 22.03%, 25.98%, 26.75%, 16.94% and 17.34%, respectively, from the base values, and that the oil is suitable to use for 10,000 km.
