ISO Grade 68 flashpoint is 430 degrees 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.
i made this mistake on an hydraulic breaker pack,no damage was caused to the pump or breaker.however the operation of the equipment was sluggish until the machine really warmed up.presumably because the 46 oil is" thicker" than the iso 32
vg stands for viscosity grade. Hydrualic oil comes in many grades.
Use Bobcat (Orange) Hydraulic Oil. If you don't have access to this use hydraulic ISO 46 for temps of -40 to 80f. Use ISO 100 for +40 to 120f. 10w30 motor oil will also work in a pinch but try not to mix....go back to hydraulic at next change.
The "Pour Point" of engine oil is about -44ºF.

The Ford 134 oil is a Hydraulic/Transmission Oil these appear to answer your question. See the provided links I would however recommend AMSOIL's SYNTHETIC TRACTOR HYDRAULIC/TRANSMISSION OIL ISO 46, SAE 30 See provided link.
Depends on the fire point stated in techincal data sheet for particular item. Generally , Motor Oil start flashing at 220 - 240 degree celsius. Hydraulic Oil flashing at 200 - 200 degree celsius. Jet fuel flash point , 38 C . Open air burning at 260 - 315 C
Smoke point: reaching this temperature the oil support a thermal dissociation (and degradation) process: formation of glycerol and fatty acids, acrolein, etc. A great smoke point is a quality for an edible oil. Flash point: temperature of combustion; the flash point is of course greater than the smoke point.
The flash point can be used to determine the transportation and storage temperature requirements for lubricants.
Ethanol: Flash point is 13 °CPropanol: Flash point is 22 °CHexanol: Flash point is 59 °CVegetable oil: Flash point is 327 °C
