The right choice to use for car hoist is hydraulic fluid for your Car Hoist and Most Car Hoists manufacturers will recommend Hydraulic oil AW32 or AW 46.

The Hydraulic oil systems in hoists don’t require “topping up” as hoist doesn’t use a great amount of oil unless a seal gives way or wears, the colour of the oil needs to be the same otherwise you create what is called a cocktail.
