So this really stops the leak.
I had a very small oil leak from the gearbox, about 4-5 drops per day. First I tried Xado stop gearbox leak - no effect, then I tried Lique molly stop gearbox leak - the leak decreased, but 2-3 drops remained per day. Now I changed the oil with new one and put this Bars additive. After 2 days of driving the leak stopped, there is not a single drop on my garage floor! So this works, and the gearbox shifts better. I am satisfied!

GREAT PRODUCT!
My girlfriend has an 08 rav4 that had a leaky rear axle seal and viscous coupler. The leaks were both fairly small but within a month the differential would be down to about half full which made me very weary whenever she had to go somewhere. The last thing I would want is to put a rear diff in her car. I typically don't trust these stop leak type of products because in my experience they're usually just snake oil. I read the reviews and figured I had nothing to lose so I tried it out. I must say this stuff is amazing, I added just a little bit over the recommended amount to the rear diff and 2 months later the fluid is still full. I often look under the car to check for drips and there is never a drop. There used to be small drops of gear oil hanging off of the diff about to fall onto the ground but this has completely stopped. You can still see where a very negligible amount of gear oil is leaking down the side of the diff below the seals so I don't think the leaks have stopped 100% but more realistically they've probably stopped about 90-95%. This additive is probably more of a temporary fix because leaking seals usually get worse over time but it's gotten me 2 months without having to pull cv axles and replace the seals so I am very pleased. I cannot speak on the gear repair or ability to stop noisy rear axles that this product claims because I didn't have that issue but it's ability to stop leaks seems to be great. I had very slow leaks and it did well for me but I doubt this stuff would help with more serious leaks. Overall I think this is a great product! Quality: 10/10 Price: 10/10 Leak repair: 9.8/10
