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!

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.

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

My Kubota 2370 was leaking tranny fluid somewhere in the neighborhood of 1 Qt./month. I added a bottle of SealLube 5 weeks ago. The leak has subsided to a trickle. The dipstick has read full ever since. I still have a pan under the transmission and a slight amount has leaked, but, nowhere near as much. However, the hashmarks on the plastic dipstick have disappeared and the plastic is a little soft. I don't know if this a result of adding the SealLube or just a coincidence. Has anyone else had this kind of problem? Makes me wonder if the transmission is operating at a higher temp since I added the SealLube.

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

Did not work on my diesel injection pump Mercedes

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..

This product Works. I Tried this product on 2 different vehicles. On my Nissan Frontier 2006, i had 2 Big hydraulic leaks at Front CV Axels. So i poured about 2 Oz or more of liquid to the hydraulic system at night. Next day everything leaked out of the Car EVERYTHING. I was disappointed at first thinking it just got things Worst. But i just poured hydraulic luid again without this product.... after 7-8 days, leaking on axels disappear, but i had i new leak on the Hydraulic Pump (Front Seal). That i had to pay a mechanic to fix. On my wife Car (Nissa Altima 2006), i decided to pour just a little quantity of this product, very little amount. 2 Days leak stopped. In conclusion, use this product in small amounts, as it is very powerful stuff. Also don't lose hope, it might take 1-2 weeks to completely seal the leak. 5 Stars, use it in small amounts.
