Great product highly recommend so far it does what it should.
Exactly what I needed. Now I have to fill this paragraph because there is a minimum amount of words required
Need another 150ml. So expensive to buy another bottle.
It is what it is, gear oil. It makes the spinny things with teeth spin easy without eating itself alive.
I bought this stuff to smell a bit more manly and also fill up a gear box, it really did the trick, my wife says "you really smell bad, or you stink" much more now. the 80W-90 is the rating on how many women will find you more attractive, this stuff really works. Oh and it is ok in gear boxes and differentials too.
Just what we needed for this machine for its regular maintenance
Used before and keep using it a good product, easy pouring
