Worth a Shot, and the Shot Worked

I had a small oil leak from my 2003 Hyundai XG350 that has around 100k miles. I was looking for a inexpensive solution and researched many stop leak products. This one was by far one of the cheaper options for stop leak products. Per the reviews and the price point (I think I bought for $3 and change out the door), it seemed like a no brainer to try. I tried it out and the leak doesn't seem to be happening. Granted, it didn't immediately stop, it took a few days of driving to stop the leak. But, I am happy with it and would try it again in another vehicle or the same if a leak materialized. I mean it's only a bit more than a quart of oil anyhow.

Works

Fixed a rear main seal drip. This product DOES work in suitable applications.

It works!

[This review was collected as part of a promotion.] bought this as a last ditch effort before wasting a weekend taking my engine apart. Hoping it would at least slow the leak down. As far as I can tell after a couple thousand miles it's not only slowed down, but if it's still leaking it's just barely. My poor driveway finally gets a break!
