The jack comes in a transport box made of plastic. The box was covered with me with oil. However, this oil does not come out of the hydraulic cylinders! The jack is well lubricated maintenance on all moving, mechanical parts (wheels, bolts, etc ...). So everything's alright.
The number of strokes is absolutely OK to jack to the car! I need even fewer strokes than with our old car jack.
I would recommend this product.
