Freeze, silicone does not expand with heat, neither does standard oil. The less air the better, just an FYI.
CORRECTION. standard oil does expand with heat. I worked onboard ships for many years and supervised transfering gasoline, diesel fuel, jet fuel, and lude oil from one ship to another and I can assure you that petrolium products do expand as the temperature rises. If you put any oil product into a container and change the temp of that substance the level will change accordingly. Hotter will make the level rise, colder will make the level drop. I remember how surprized I was when seeing just how much the levels of tanks would vary in changing temps. Maybe you were thinking about how you cannot compress oil. It is not compressable.
