Leak Gone, The Stuff Is Amazing

My 2011 Mini Cooper S developed an oil leak at 80K. Took it to the shop. It was a seal on a hose coming from the engine block. In order to replace they’d have to remove the front Drive and a bunch of other components just to get to the seal (nothings easy or a quick fix on a Mini. Nothing!) $1600.00. I went home removed 1/2 quart of oil, replaced with Lucas Oil Stop Leak. Drove to work and back next day around 40 miles total. Leak gone. It’s now got 85K and no leak. The stuff is amazing. Going to put some in my F250 Powerstroke w/250K on the next oil change. The stuff is amazing. -Christopher R., Ocean Springs, MS
