Bar's Leaks Engine Oil Stop Leak Concentrate, 11 oz

[This review was collected as part of a promotion.] I have been using Bars Leaks Heavy Duty Rear Main Seal during all my oil changes to my 1963 Corvette. For several years of doing this there has been a noticeable reduction of oil drippage. Several other classic car owners to include Corvette owners have used this product during their oil changes with great success! I highly recommend this product.

[This review was collected as part of a promotion.] Bought this a month ago for check engine light on referral from mechanic and has turned off ever since

[This review was collected as part of a promotion.] I use this in my old motorcycles on a regular basis. Some of them currently have leaks that I want to fix and this stuff works great. It is usable with wet clutches, which is a nice concern. I do not carry.

I bought this item 10 days back to stop smoke smoke & smell from my car exhaust... adding one bottle of this had fixed the smoke issue, so it doesn't smell any more and smoke almost gone down.

[This review was collected as part of a promotion.] I brought it a few months ago and he actually worked it well with stopping the leak or slowing it down so today I chose to buy it again

I've got a stubborn 351W that just has been driving me crazy. Two super small leaks at high rpm's. Popped in a bottle of the “good stuff “ and bam leaks gone. After car season we will address the issue. Until then thanks folks we appreciate your products!

Quickly stopped the oil leak my vehicle had. Saved me a trip to the Mechanic shop.

[This review was collected as part of a promotion.] My valve stem seals and piston rings were causing oil consumption. I was having to add about 1 quart every 500 miles. After running an engine flush and changing my oil, then adding fresh oil and Bar's Leaks Oil Seal Engine Oil Burning and Leak Repair, my oil consption has been reduced. I have not changed my oil since adding it, so I can't say if it permanently repaired my issue, but it sure is saving me in quarts of oil right now. I didn't have any external gasket leaks, so I can't speak on if it repairs those either. Best of luck to everyone and their vehicles!

Added Bars Leaks to our 2010 Honda CRV after noticing we were loosing oil slowly. So far so good, will continue to monitor over the next couple of weeks.

[This review was collected as part of a promotion.] I bought the product to help stop a small oil leak on my Toyota Tacoma. The leak did not stop but was greatly reduced. No more drips on my driveway. I have now reached 500,000 miles on my truck.
