Review: Stopped my leak - 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!

## Questions & Answers

**Q: How many do you put in a rear for noisy bearings?**
A: You fill up the rear differential through the upper plug.  When the fluid starts running out of the hole, it is full.  Make sure you are parked on a level spot.  I doubt if it will help for noisy bearings unless you are really dry.

**Q: Can I use it for automatic gears?**
A: Bar’s Leaks Gear Repair is a treatment additive for use with automotive, heavy duty, agricultural, marine and industrial gear oils. Designed to mix with all synthetic and conventional petroleum GL-4, GL-5, MT-1 gear oil / lube grades including 75W-90, 80W-90, 75W-140, 85W-140 and all others. 

We would not recommend for Automatic if you are using in Automatic please use Super Leak Fix - part number 1305.

Used some in what I suspect to be a slightly leaky (non-limited slip) differential. Good to have just in case.
