Review on 💪 3-Stage Stainless Steel High Pressure Hand Pump for PCP Air Gun, 4500psi, Ball, Tire, Boat Filling - Includes Stirrup Pump (Silicone Oil NOT Included) by Sean Maples

Reviewers here talk about buying silicone oil to lubricate the pump, but "silicone oil not included" in this list is silicone oil that should fill the gauge! It's a blatant omission that they don't state that the missing silicone oil is for the gauge. So you get a dry meter that you need to fill with silicone oil that you need to buy. Silicone oil really isn't that cheap. You can replace the silicone oil with glycerin, the only difference is the operating temperature. Silicone oil is the best! If you're planning to save a few bucks but need to buy oil, you might be better off buying a pump that comes with the oil already in the gauge. The reason for rejecting oil is that they may not be able to export to the US with liquid in the cores. This pump is also said to be LIQUID COOLED! If this is the case, there may actually be no coolant for the pump. .so what's the use of advertising it as liquid-cooled when in fact there is no coolant? These can be imported from China but are sold here by dealers who can fill the gauge and pump with the necessary oil themselves. and coolant if necessary. The photo they provided SHOWS a pressure gauge filled with silicone oil! What gives?
