  2. SAE J300 - Wikipedia

    en.wikipedia.org/wiki/SAE_J300

    The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.

  4. Viscosity index - Wikipedia

    en.wikipedia.org/wiki/Viscosity_index

    Historically, there were two different oil types recommended for usage in different weather conditions. As an example, with winter oils and cold starting the engines, and with temperature ranges from, say, −30 °C to 0 °C, a 5 weight oil would be pumpable at the very low temperatures and the generally cooler engine operating temperatures.

    en.wikipedia.org/wiki/Automatic_transmission_fluid

    Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an automatic transmission. It is formulated to ensure smooth valve operation, minimize brake band friction, facilitate torque converter function, and provide effective gear lubrication.

    Tractor fluid (a universal transmission, gear, hydraulic, and wet brake fluid) Gear oil; In the engine oil family, there are four basic oil sub-families: Multigrade conventional oil—in SAE 10W-30 and 15W-40 viscosity ranges; Multigrade synthetic oil—in SAE 5W-40 and 15w-40 viscosity ranges [3] Single grade conventional oil—in SAE 20, 30 ...

  8. Operating temperature - Wikipedia

    en.wikipedia.org/wiki/Operating_temperature

    An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...

  9. DEXRON - Wikipedia

    en.wikipedia.org/wiki/DEXRON

    The AST had two driving ranges (low and high). In low range, the transmission would shift from 1st to 2nd gear and then hold in 2nd. In high range, the transmission would start in 1st gear, jump to 3rd, then shift to 4th gear. The driver could change ranges with a flick of a finger.
