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!

Noticed a leak while in arizona, wasn’t expecting much if anything. I am surprised because so many “snake oil” products don’t work. My pinion seal was leaking had about 800 miles to home. Put it in and topped off differential when I filled up with fuel. The next fuel up about 350 miles I checked the diff, no leak, checked to be positive I had fluid in it still and was surprised it was 3/4 full still. Topped it off and went on. Checked the next fill and was still full. I’m happy, but still getting seal replaced. It worked in a pinch!
