In daylight, and again at night under a shading canopy, we observed the behavior of bottlenose dolphins (Tursiops truncatus) allowed to swim freely in a pool with three surface divisions, one of which contained either clear mineral oil, dark-tinted mineral oil, or a thin sheen of refined motor oil. Overall, they avoided oil both during the day and at night. The response broke down when we presented them with a thin sheen, especially at night; we suggest that such conditions represent the threshold for their ability to detect oil or their desire to avoid it. Irrespective of light conditions, the dolphins' tactile sense played a more important role than vision in perceiving, and ultimately avoiding, oil. The strength of their basic reaction dampens our fear that they might be unknowingly subjected to prolonged or repeated exposure to oil at sea.

Two trained bottlenose dolphins, Tursiops truncatus, were tested for their ability to detect visually 12 different oils and 22 oil mixtures confined at the surface in small cylinders. Detection thresholds were established in tests using progressively lighter substances. The animals detected 6-mm slicks of crude, residual, and refined motor oils, and diesel slicks thicker than 17 mm. They could not detect 6-mm thicknesses of leaded gasoline or transparent mineral oil. One dolphin's ability to detect oil improved with experience. While blindfolded, one dolphin could detect 12-mm-thick samples of two crude oils, Bunker C and mineral oil, but only when the latter two were churned and contained air bubbles. We conclude that dolphins detect the thicker concentrations of oil that occur near the source of an oceanic spill, but not lightly colored or refined products that tend to disperse into thin films.

<p>This paper is written to show comparison between the naphthenic mineral oil with namely olive oil and sunflower oil in the context of voltage breakdown as insulating transformer oil. Olive oil is known to have been tested as alternative oil for transformer insulation and sunflower oil is a new oil being tested in this paper. The oils are mixed within certain ratios in order to determine the withstand breakdown voltages. The relationship of the breakdown voltages are also tied with the viscosity of the mixtures, and the mixture of oils are also exposed to ageing test and of tan-delta balancing test. All test follow IEC60156 standard test procedure for liquid insulation test. The mixtures were compared to the existing mineral oils and the findings will be discussed.</p>

Additives, which are used to reduce wear and friction coefficient and are added into petroleum-based oils in various amounts, are known to be harmful rather than beneficial unless an appropriate working environment is used. It is critical that additives are utilized in the form of motor oil additives at the right time and in the right amount. This study aimed to determine wear performance of commercial borax[Formula: see text] product by adding a borax additive into the system at various working temperatures. In this study, mineral oil was heated at three different temperatures ([Formula: see text]C, [Formula: see text]C and [Formula: see text]C) and wear performances were determined by adding commercially produced borax into mineral oil at these temperatures. It was seen that wear performance of commercial borax additive was not good at low temperatures. However, wear performance was better when the additive was added into the oil at temperatures higher than [Formula: see text]C.
