“…There is recent research about its origins and its evolution along ODI, and there are some expectations to find more specific ways to detect oil deterioration point through this parameters. [27][28][29] On the other hand, FT-IR has been assessed recently as an analytical technique to detect presence of certain types of additives (due to the presence of characteristic molecular bonds), and some methodologies have been developed to quantify them. 30 In this study, it has been used to quantify the aminic and antiwear additive depletion, using FT-IR spectra methodology measurement procedures based on ASTM D6810 31 and ASTM D6971.…”

Low viscosity engine oils (LVO) are considered one of the most interesting solutions for improving fuel economy in internal combustion engines (ICE). There are different studies involving LVO and ICE, but currently limited data are available regarding "real-world" performance of LVO in a real service fleet. Included in a broadest study related with fuel consumption saving effects and performance of LVO in a real service fleet, the aim of this work is to present the results obtained in terms of comparative oil performance.So, on this test, a comparative analysis using 39 buses was performed, based on a deep and extensive oil analysis program to assess those aspects above mentioned. Two engine technologies (Diesel and CNG) were considered and four different lubricants, two of them LVO and other two used as a reference baseline. The test duration comprised two oil drain intervals of 30000 km each one, totalizing more than 2 million of kilometers accumulated.Results have shown that LVO presented an excellent performance along the oil drain interval (ODI), even improving some characteristics of the baseline oils with higher viscosity values. Results have shown that oil degradation is more dependent on engine technology, but in any case presented a penalization in terms of ODI reduction, a key indicator for end-users related with maintenance costs. In the case of CNG engines, higher oil degradation in terms of oil oxidation and nitration was observed.

“…Comparative studies between Diesel and CNG engine oils performance have shown accelerated oil oxidation and higher engine wear rate for some metals such as copper on CNG engines, as a consequence of higher stress suffered by those oils related with higher thermal stress . This situation has been observed on formulations recommended by the own engine manufacturer.…”

This work presents a comparative assessment of engine oil performance on field test using urban transport vehicles powered by CNG engines using two different mineral oil formulations approved by engine manufacturer. The first one is considered as a baseline reference, and the second one is a higher quality formulation in terms of base-stock refining and additive content. Higher quality oil has shown a significant enhanced lubricant performance, leading to reach the oil drain interval defined by engine manufacturer on these engines without penalties in maintenance costs.In order to assess oil performance, an oil analysis program has been established for oil samples collected from vehicles operated under real service conditions in an urban transport fleet. Monitored parameters include: oxidation, nitration, aminic antioxidant additives depletion, anti-wear additives depletion, TAN, TBN and RUL number (as an estimation of antioxidant additive depletion including aminic and ZDDP).Results obtained in more than 90 samples from 15 different vehicles have shown higher degradation rates for low quality lubricant oil formulation. This deviation can be explained taking into account factors related with lower antioxidant additives content and lower thermal stability that can be mainly related with the base stock quality. This lower oil performance can be finally converted into higher vehicle maintenance cost and lower engine reliability
