Before using any jack, it is necessary to check the quantity of oil it contains. Usually, there is a lack of quantity. Empty the old oil and put new oil in the correct amount. It is understood that it is oil for hydraulic systems and not engine oil. Check at least every 2 years.

I bought it in the summer. The first winter, I change the tires on all 4 of my cars (from summer to winter tires). I repeat the process in the spring and the same thing happens for the next 2 years. So, I have functionality for 3 years - 6 seasons - 24 times times 4 times lifts for tire changes on each car = 96 uses.

Guys, that was it. In the 4th year, it started leaking oil, the gasket came off, I repaired it, but it can't lift anymore. Let's stick with the 96 uses.

Just for the record, the other jack (from a different manufacturer) that I have in my other house has been doing this job continuously for 23 years without any problem.

The conclusions are up to you.

3 years later it started losing oil, I filled it with 20w oil for suspensions, we will see how long it will last, and be careful when lifting it so as not to damage the car
