And if like me the quicker you try to be the more you'll loose due to fumbling. So just take old one off, put new one on, no rush. You will loose some but it should not be to bad.
That Super UDT is expensive but is so worth it. Don't try any other hydro oil. I've only heard the bad stories of those who have tried, no one that I know of has switched and been happy with the outcome.
Good luck.
