Not a believer of snake oil, but for once it actually blew my mind had a rear main seal leaking on Ford 4.6. It has high miles so I wasn’t too upset about it, but I wanted to give this a try to my surprise. it actually stopped the leak and after reading other people‘s reviews claiming it takes a few days mine actually was good after just one day I did put approximately 10 ounces in. I bought two bottles. I’m gonna run it another week and then do an oil change. I’ll see how long it lasts.

Product worked great on my internal hydraulic leak on my tractor needed 4 bottles took care of a 7 gal hydraulic leak resevoir where pump was leaking

Have 1520 John Deere tractor with a major hydraulic lift leak. It leaked even when the tractor wasn’t running. Supposedly, SealLube would cause the o-rings and seals to soften up and regain some of their elasticity. This product is working as advertised. It has saved me over $2500.

I've used another brand at one time. Front main seal was/is leaking. I think this helped, but after an 823 mile trip it still leaks some. So did not completely stop the oil leak.

Amazing additive. It really works! I had to have the rear main bearing seal replaced on my tractor at 600+ hours. The dealer charged $3100. After an additional 900 hour the seal started to weep again. I added a bottle of Seal Lube and haven't seen a drip in the last 1200 hours. Great product!

Did not work on my diesel injection pump Mercedes

Had bad powersteering leak dripping on floor(1-2" each day) and poured in couple oz SealLube and no more drips. Still have damp hose, but no drips. Big improvemnt

I own a 2004 Mazda6s with a Ford 3 liter V6 engine. Its got 148,00 miles on it , I've had numerous oil leaks fixed on it over the years. These engines are known to leak oil. Recently the timing cover started to leak , took it to the dealer for repairs and was quoted $1800 to fix the leak. Yeah Right !! I told the dealer NO. A Mazda mechanic pulled me aside and showed me this product which he said he personally on his own has had great success with. He said it would not hurt the engine in any way. I thought I have nothing to lose, ordered some from Amazon, it arrived quickly , installed it as directed and behold with in 100 miles leak was completely sealed. Saved me a bunch of money. Cleaned up area to be sure and the leak has not returned... Totally Satisfied..
