Rated 5 out of 5 by this product is the best that i used Is an excellent product August 8, 2016
Rated 1 out of 5 by 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! March 30, 2016
Rated 1 out of 5 by Still leaking Used this several times in my 96 jeep grand and didn't work,seal may be beyond any quick fix. November 9, 2015
Rated 4 out of 5 by 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. September 22, 2015
Rated 5 out of 5 by This product works! I was really surprised that this product works. Although, the instructions say that the leak should stop after 3 days of driving; my leak stopped after a week of driving. I'm still very happy that it works. September 14, 2015
Rated 5 out of 5 by Really Works I have been using this for a few years now on all my classic and antique vehicles. Not only for the motor but also in my transmissions and differentials. As long as the oil isn't shared with a wet clutch it will be fine. The seals rejuvenate and takes care of leaks. August 20, 2015
Rated 4 out of 5 by 80% effective Expected the product to STOP the oil leak 100%. I'll settle for the 80% effective as it is better than pulling the transmission. August 8, 2015
Rated 5 out of 5 by works had a slight leak from the main seal, mechanic said to put in an additive and it might fix it. Put it in and the leak is gone. July 27, 2015
