The "Pour Point" of engine oil is about -44ºF.
The cross reference for m-4864 which is a hydraulic oil or transmission fluid is SAE 80 for below freezing temperatures. B (SAE 90) is used for temperatures that are above freezing.
The freezing point for Peanut Oil is 3 °C (37.4 °F).
No, it become unusable at that point. Gasoline has a considerably lower flash point than hydraulic oil, and hydraulic oil gets heated when it is in use.
Freezing oil will be extremely viscous. Oil does not freeze easily. The freezing point of oil is very low like -30oC.
Under normal conditions no because the hydraulic fluid is usually oil based. In conditions that are not normal like space or lab conditions that are beyond normal temperature yes there could be a chance, but very unlikely.
SUBSTANCE FREEZING POINT corn oil - 20 deg. C sunflower oil - 17 deg. C olive oil - 6 deg. C sesame oil - 6 deg. C peanut oil 3 deg. C palm oil 24.1 deg. C coconut oil 25.1 deg.
Hydraulic fluid and hydraulic oil are one in the same.
hydraulic oil
Lower than -18 c as I have tried.
259 K equal -14 oC.
emolliating hydraulic oil in the lowest part of the hydraulic system.
The freezing point of Mustard oil is -5°C.
