It worked like magic. My leakage was even into the 2 chambers with resulting poor firing and poor performance. The repair sign was always on and during worst times the engine management light come on instead of the repair signs. After adding this product to the engine oil I went on a long drive after which i noticed some improvement. After a day or two my engine management light changed back to repair then after another two days both lights were out and my engine performance returned to normal. It has remain so ever since. My engine oil level was always difficult to read because there was iol stains all over the stick one in the channel. Cleaning the stick never helped I was even thinking may be there was too much oil in the engine. However the same thing continued after a service when not more than the amount of recommended oil was used. It was while changing the plugs i saw so much oil in the first chamber and the plug was drenched in oil. I tried to blow out the oil and replace new plugs but after a few days the performance got worse even with new plugs. after a few weeks i thought i should change the plugs again . I found again that the first plug was soaked but not only that the second one was now also soaked. That was when i thought there was serious leakage . I search for how to treat leakages . I came across this product and it has proved wonderful. I highly highly recommend this productRead full review

I've had a leaking crankshaft oil seal on my corsa. After adding one can of this it gradually reduced the loss of oil. Not completely stopped the leak, but I have bought another can to add.. hopefully this will improve things.
