Bar's Leaks1000 High Mileage Engine Repair, 16.9 oz | Restores Performance, Increases Compression & Horsepower, Stops Leaks, Noise & Smoking

I have a (2006 gmc sierra 1500)My truck was leaking oil, for about a year, it got worse as time went on, and I decided to use this product, I used it when I did the oil change, and to be honest I don’t see dark spots of oil on the floor like I use to..it’s actually works!! And on top of that, my engine is very smooth and stabilize…

Brought back life in my old dodge. I've got a crack in the manifold along with a broken screw in the engine block where the manifold mounts. Major pain to fix, on the fence with either fixing it or doing a motor swap. Used this for the time being and it's improved the performance, reduced engine noise and I noticed a slight reduction in gas use. It also lubes and restores a lot of the seals which is supposed to reduce smoke levels. I've never had an issue with smoke, but anyways it's worth it 100%.

Stops the bmw smoke issue for a good while. Worth every penny.

I have a Silverado with a small leak from the oil pan's seal, I am not trying to do all that so I thought I'll give this product a try, I'm gonna tell you the moment I started the truck it the truck felt like if it was new, the truck used to shake a little during idling, after using this product it was running so smooth that u can actually cook an egg in the engine, then I noticed the leak was gone, I usually don't push for snake oil but this product works well

Difficult to use because on one side of the bottle, the liquid is very watery, and on the other side of the bottle, the liquid comes out like honey. So the watery liquid all dumps out first, which filled up my oil receptacle before the thick liquid would come out. Instructions should advise customers to poke a small hole in the safety foil on the watery side and completely remove the safety foil on the thick side if you want this to actually mix as intended. Can't tell if it is doing anything, but probably not since I didn't get both sides of the bottle to pour into the oil receptacle in the car, and now it is full. Poor design.

very pleasantly surprised i bought this for valve seals was getting a little smoke on start up don't know if it improved that problem yet but noticed the engine is much more quiet and more power

Edit -- After about 1 year, Bar's Leaks stopped working. The gaskets on my Oil Pump and Valve cover had completely worn out. Cost a couple hundred dollars to replace, but the oil leak is gone. That said, getting 1 year of driving out of a bottle of this stuff still leaves me very impressed. I'd use Bar's Leaks more as a way to get you to a spot where you can get your car fixed instead of an end-all solution personally. 5 stars for 1 year of stopping an oil leak at the cost of $7.Original ReviewI can't believe this worked.I had one of those "everything went wrong" moments with my 2001 Camry. For a few days in a row I noticed a burning smell when I got out out of my car. Third day I noticed it, checked the oil level - nearly empty. I had changed the oil a couple of weeks prior so this was a bad, bad leak.Drove to a mechanic who only gave bad news. They said they saw multiple leaks on it, and that it'd be somewhere between $1500-2000 to fix. Took it to a second mechanic who said the same thing. On the way to the second mechanic, the check engine light flipped on, the burning smell was worse than ever, a brake light burnt out, and I was about ready to bite the bullet for the repairs.On a whim I bought a bottle of this stuff. For 8 bucks what the heck, why not. My engine had lost enough oil in a couple of days to add the full bottle of the engine repair. It said to drive it for 100 miles for best results so I visited a friend that evening 200 miles away (probably not my smartest moment since I was having all the car troubles but whatever). I pulled in and looked under the car - no dripping. Spent the night and the next morning checked under the car. There was a puddle maybe the size of 4 or 5 drops of oil.Since driving home from the friends (1 month ago), the oil hasn't leaked a bit. Took it to another mechanic who said everything seemed to be looking great.I'll check the oil once a week for awhile then probably longer intervals, but it seems like this stuff worked. Even if I have to add a bottle of it every so often, it's way cheaper than the quotes I received were. I was (and still am) completely dumbfounded.

I used a ton of this S* in my Mountaineer before I realized that my F* oil sensor plug was actually leaking. $20 and 15 minute fix. However, I use this stuff in all my older vehicles and any seal leak stops after a week or so. Good S* ! A must for older motors. Good price.
