“…TBN and TAN are significant indicators of oil deterioration depending on the oil’s initial value. The rate of TBN depletion up to the predefined limit or TBN/TAN crossover point is accepted to be an indicator of the deterioration (Troyer and Fitch, 1999; Batko et al , 2001; Lacey et al , 2003; Suzuki et al , 2003). ASTM D4739 and ASTM D2896 are the common methods of determining the exact TBN, which have to be chosen according to the range of different sources of acids (Burk et al , 2007).…”

AbstractPurpose -Zinc dialkyldithiophosphate (ZDDP) is the most common anti-wear and anti-oxidant additive. ZDDP is the primary origin of zinc, sulfur and phosphorus, which are well-known poisonous elements for commercial after-treatment systems. The aim of this study is to investigate the optimum oil drain interval of non-phosphorus and non-ash (NPNA) engine oil that was developed as a prospective alternative to commercial phosphorus-containing (PC) engine lubricants. Design/methodology/approach -The results of a fleet test wear debris analysis were used to optimize the oil drain intervals from the perspective of cost. Findings -Drain intervals of 32,000 and 28,000 km were computed as the optimum values for NPNA and PC engine oils, respectively. Extending the oil drain intervals up to the obtained mileage may go to a total saving of €43,045,084.2 for PC engine oil and €49,253,998.6 for NPNA engine oil with respect to the total sales figures of test vehicles in Turkey. Originality/value -Maximizing the lubricant life has environmental benefits and is the easiest way to reduce the maintenance cost of a vehicle. The protection of after-treatment systems against lubricant-induced poisoning is a great challenge. The most important result of this investigation is the lower operation costs of catalyst-friendly lubricants in spite of their low anti-wear additive performance.

ROBO—A Bench Procedure to Replace Sequence IIIGA Engine Test

A constant quest but a difficult goal is replacement of expensive and lengthy engine tests with more cost effective bench tests. This paper will report on development of a bench test, the ROBO, as a potential replacement for the Sequence IIIGA, an oxidative oil thickening engine test now part of ILSAC GF-4 specifications. Sequence IIIGA, a gasoline fueled engine running under severe conditions, is used to condition oils prior to determining TP-1 MRV viscosity, a cold temperature and low shear rate measurement. After Sequence IIIGA conditioning, candidate oils must meet SAE J300 pumpability limits at no more than 5°C warmer than its original SAE W grade. The ROBO bench procedure has been developed to potentially replace Sequence IIIGA engine aging by mimicking, to the degree possible, oxidative conditions found in the engine conditioning procedure. ROBO conditions were developed by employing the three Sequence IIIG ASTM matrix oils and comparing their used oil rheologies from multiple Sequence IIIG and ROBO runs. The results from the final ROBO conditions compare well not only for TP-1 MRV but also for KV 40°C and CCS. To further test the correlation of bench to engine conditioning, a set of diverse oils (various SAE viscosity grades and DI chemistries) have been examined; these viscometric data from ROBO and Sequence IIIG also compare favorably with only a few anomalies. Finally, the status of industry acceptance of ROBO will be discussed.
