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

[This review was collected as part of a promotion.] This is my second experience for this product. The first time it worked very well and I would expect the same this time! It is a great product for cars that sit for an extended period without being driven or started on a regular basis.

[This review was collected as part of a promotion.] I have bought this product 3 times for different vehicles. I bought my most recent bottle last weekend because it works so well and saves a lot of money compared to taking my vehicle to a repair shop. No oil spots on my driveway and no big mechanic bill!

[This review was collected as part of a promotion.] I recently repaired the oil pan in my Malibu but there was still a small leak somewhere else on the engine block that I could not find. This stuff came to the rescue. It seems to have stopped the leak. Hopefully this will keep things running well moving forward.

[This review was collected as part of a promotion.] I used two bottles in my vehicle which holds 8.5 quarts of oil and can already tell that the leak has either stopped or slowed down significantly. I was skeptical at first but believe this product does what it says.

[This review was collected as part of a promotion.] I used this product in the front and rear differentials that were leaking at the drive line yokes. After the first 100 miles we noticed a considerable difference in the leak being a lot less. By the the end of the forth day we pressure washed the underside of the car and it has been dry ever since that been 60,000 miles ago. Now the rear engine main is starting to show some seepage and am going to add a bottle to the engine oil.
