Usually, Hydraulic systems have immersion heaters installed for this very purpose in cold weather. ATF flows the best in cold weather, but isn't for all applications.

cold crude will not let all the bs@w compleitly out. if you heat to 140 temp then spin the oil at a high rate the water and the bs will fall out of it... also hot and cold will have a weight difference............ it will change the gravity.
"winter" The oil will act like 15 weight oil in cold weather and 40 weight oil in warm weather.
1w30 in warm weather, 5w30 in cold weather
The "W" stands for weight. The "W" stands for winter. 5w30 is a multi viscosity oil. It acts like both 30 weight in warm weather, and 5 weight oil in cold weather.
5W30 in cold weather. 10W30 in hot weather.
5w30 oil is thinner in cold weather at 5 weight, and is 30 weight at full operating temperatures. 10w40 is heavier in cold weather at 10 weight and heavier at full operating temperatures at 40 weight.
SAE 30. When the weather gets cold go to a 10W30.
Use "Hydraulic Jack Oil" only
Basically, the only difference between HD-46 and HD-68 hydraulic oils is the weight of the product. HD-46 is a 15 weight oil, but HD-68 is a 20 weight oil.
Factory says, Cold weather 5W30 weight only. Hot months 10W30 weight. Do not use any heavier weight are it will destroy the valve train.
The weight of the oil and flow rate. The 5w30 will flow easier when cold than the 20w40. It is 5 weight oil when cold whereas the other is 20 weight when cold. When the oil reaches full operating temperature the 5w30 is 30 weight oil and the 20w40 is 40 weight.
30 weight non detergent oil. 8 gallons
The answer to this depends on what kind of oil you are talking about. If you put a heavier weight oil (like 5 weight) in your car instead of say,30 weight, it will cause your car to act sluggish in the cold weather because the oil is thicker. If you put a lighter weight (30 weight ) in a vehicle that needs a heavier oil, the car will still run but not as well as using the correct type of oil. If you put transmission oil in your car's engine oil pan by mistake; you should empty out the oil pan immediately (when the oil and car are cold) and flush it or refill it with the correct oil as soon as you have realized it was the wrong oil.
