Rated 1 out of 5 by ToplessTom No difference in oil loss.
Maybe the rear seal on my 2003 GMC 4.8 is too far gone, I don't know. I do know that this stuff did nothing to slow the leaking rear main seal.

Rated 4 out of 5 by CHUCKCHUCK555 worked as expected
It did slow down the rear main seal leak somewhat but has not stopped the leak 100%,, My Gasoline 6.0 liter Chevy motor has 275,000. miles!
so I am satisfied considering the mileage

Rated 4 out of 5 by B173 good stuff
Hi I have put this product in about 2 weeks ago before the bars stop leak
i had 128333 miles I changed the oil & filter then installed the bar's leak stop, & within 90-100 miles checking oil level everyday after another 200 miles the leak stopped / I'm so happy that I do not have to spend $ 4,000 for engine work / that price is not Pep Boys Price / But overall I would tell a my friends
about this good product / Thanks.

Rated 5 out of 5 by Tatartot This does what it says it will do
My car has over 350,000 miles so that the rear main seal was starting to leak. This product slowed down or stopped the leak all together.

Rated 1 out of 5 by HBHarleyman Didn't work for me
I thought I'd give it a try on a car I just purchased, and the mechanic said I have a rear main leak. I actually tried it twice with two different oil changes, after it didn't work the first time. It didn't appear to slow down my rear main leak at all on my RX300 Lexus. Off to the mechanic to get the rear main seal replaced, and put his kids through college!

Rated 4 out of 5 by Seal Good Product
Reduced the leak substantially but not completely. Seals were damaged due to clogged PCV system which was replaced and cleaned. Will use another bottle of Bar's RMS during next oil change to hopefully recondition and seal the system.
