Leak is considerably less

Hi guys. Engine oil stop leak 1010 is the product I used, and that's what I am reviewing here.

I have a leaking rear main seal. Used the product and the leak is considerably less and seems to still be improving even after six months.

Stopped the leaking

I have used the Engine Oil Stop Leak Concentrate (part 1010). I used it in my mother-in-law's car because it was dripping oil. After putting it in and following the instructions it stopped leaking!

Powerful stuff

I’ve used the Engine Oil Stop Leak Concentrate (part 1010) about a year ago. I had a 2006 Chevrolet Silverado that was diagnosed with a rear main seal leak. Tired of spots all over my driveway, I thought I’d give it a try. I changed the oil and added the product & drove across town on an errand. I parked in a different spot after I returned home & next morning saw only 2 spots. I drove again about 15 miles to pick up supplies & back home. Next day no new spots. I was surprised but happy that the leak was stopped. It’s been 9 months and still no leaks. This had saved me about 2 qts.of oil in between changes. Powerful stuff I’d recommend for anyone with an engine oil leak!

Great customer support too

I used Engine Oil Stop Leak Concentrate. I used this on my 2002 Honda with 204,000 miles. It helped stop the small leaks in this engine within a couple hundred miles. Two years later...the leaks are still sealed. By the way, Bar's Leaks customer support was excellent - I called them looking for recommendations and they were very knowledgeable.

No more oil leaks

I use engine Bar’s Leaks Engine Oil Stop Leak Concentrate. Use it on each oil change. Keeps oil leaks to bare minimum.

 by Allen L.

As an average car enthusiast and reseller at a local store I feel I am in the know. My car was burning oil and having been such a young vehicle I thought I would try the Oil Stop Leak Concentrate in addition to my next oil change which I do myself. Almost immediately I noticed that the burning lessened and eventually came to almost non-existent. Thank you for keeping my car on the road.
