The hose is slightly thick and stiff, which in the beginning was not a problem.
Then in the end I just could not get to the lowest point of Diferentials.
My colleague had then the idea reinzustecken into the tube with a piece of wire about 20cm length and bend then, with indeed the tube has bent.
So I came easily to the lowest point and could almost suck all the oil.
At the start of pumping it needed villeicht 4-5 strokes and the oil ran out of their own accord.
Later, when the oil level is less then you had been there little play around with the hose, but the pump really sucked everything out.
This product is a recommendation to buy !!
That the tube is now too thick unfortunately suck to as engine oil through the dipstick so, but again, you can safely super help by taking a copper pipe and then connect to the hose, hose clamp off and already one has a super pump suck to even motor oil.
All the negative reviews are accurate due to the fact that everyone expects a universal device but something there not at the price.
Little dexterity and technical understanding should already be in place, after all, wants to suck the engine oil out of a car and not a drink through a straw!
