Abstract
Purpose- This paper aims to determine the usage time of the test lubricant N0, prepared from base oils of Aliaga Plant, Izmir, in gasoline and diesel-engines, and the investigations of high-temperature oxidation, engine-protective properties, and property changes of the lubricant in performance time.Design/methodology/approach- Physical and chemical properties of the lubricating oil were initially established, and the oil was then subjected to Petter W-1 gasoline and Petter AV-1 diesel test engines. Dismantling of the engine parts was followed by the examination of pistons, piston rings and bearings, and analysis of the lubricant was also undertaken. The engine performance test results and the quality control of the lubricating oil assessments were evaluated according to the International Engine Lubricant Specifications.Findings- The lubricating oil, under sluggish experimental conditions, appears to meet a 40-hour test in gasoline engines and a 120-hour test in diesel engines with the specifications. This means that under usual working conditions the lubricants keep the engine protective properties in 7,000 km distance for gasoline run-vehicles, and in 5,000 km distance for diesel run-vehicles, after which change of the oil is required.Originality/value- The paper provides information of value to those involved with lubrication and engine performance. © 2008, Emerald Group Publishing Limited
