Has limitations, but works well
This product will stop a leak where it's caused by degrading oil seals perfectly. What it won't do is seal a punctured sump or sort a broken crankshaft seal. Been using it for years along with their oil treatment product. Both excellent.

❤️ Fabtastic stuff! ❤️
Purchased twice now... 1st one a disaster as I put this into my engine with a top up of fresh oil, which resulted in me over filling 😡... had to purchase an oil syringe to remove overfil and leak continued. Weeks later had an oil and filter change done professionally ☺️ not a drip or drop seen on my long suffering driveway. Fantastic stuff and saved me £1800 for replacement of seals etc.... ❤️ love this stuff!!!!!

STP engine stop leak:May be for very minor leaks!
Didn't do much with the oil leak, may be this is more for very minor leaks.
