u can use thick oil or engine treatments like slick 50 or something , or u can use piston Seal compound but get it done by a proper mechanic

If your compression is down to 40 psi you have a serious issue with that cylinder. A heavier oil will help some if the problem is rings. If the problem is valves it wont help at all.
