Artificial Aging Experiments of Neat and Contaminated Engine Oil Samples

This study highlights how the results from an artificial engine oil aging method compare to used samples collected a vehicle fleet. Additionally, this paper presents effect of contaminating during with synthetic fuel alternatives on physical and chemical properties artificially aged samples. A laboratory-scale thermo-oxidative experiment was conducted multiple commercially available formulated fully-synthetic SAE 0W-30 oil. The goal establish validity as well underlying process in reproducibly fabricating small batches comparable real-life oils. Eight were subjected distinct load cases (temperature, air flow rate, sample volume time). Six additional intermediate case, five them contaminated selected conventional fuels novel automotive candidates. Conventional analysis each determine oxidation, residual additive content, kinematic viscosity total base number. compared in-use through PCA. resulting condition after is accordance independently published terms zinc dialkyldithiophosphate content viscosity. Contaminated OME 3-5 resulted drop antioxidant elevated Based comparison samples, 200 mL at 180 °C 1 L/min for 96 h can produce similar conditions mixed use 7000 km.
