Bar's Leaks 1000 High Mileage Engine Repair, 16.9 oz | Restores Performance, Increases Compression & Horsepower, Stops Leaks, Noise & Smoking

Had an small oil leak on my 2005 F150 with 220,000 miles and lifters tapping constantly but after adding this after about 2 weeks the leak stopped and tapping stopped, ive tried every additive available and this is the only one that worked, just bought more for my 97 F150 also, it really does work

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%.

Used this product on a Honda Accord 1999 EX 4cyl. Car was leaking oil. I had to refill a quart every 2-3 weeks. Mechanic informed me the car was leaking in numerous spots but the biggest area of concern was the rear main seal.I tried some Lucas Oil 10278 stop leak but it made zero difference after 3 weeks. Before deciding to pay my mechanic around $1200 (my car is only worth $2000!) for all the seals and gasket repairs, I used this Bar's Leaks 1000 engine repair. Poured the entire content in the crankcase before heading out on a fairly long trip. I was honestly surprised it worked within a week. I was expecting it to at least just slow the leak down but the leak has stopped completely and I haven't had to pour in oil nor have I seen any drips. When doing an oil change I found the underside of my car completely dry.I'll update this review as time goes on to inform how well it holds up.EDIT 3/19/2015The leak has returned but it is much smaller than the initial leak before any Bar's Leak engine repair was added. I decided to give it one more try. I bought another bottle of the product and poured it in. It has been 3 weeks now and the leak is gone once again.So far in my case the product can be deemed as just a temporary solution. Some reviews here have claimed that two bottles will do the trick so I am holding on to that shred of hope that this second bottle will permanently seal the leaks. I would still recommend the product for the price alone.EDIT 8/20/2015No leaks as of today! Seems like the second bottle did the trick.Final Edit 11/23/2015After virtually a year of no oil leaks, this product held up for my 99 Accord.However, last month I tried the product on a friend's 97 Accord, with a minor rear main seal leak and it did not work at all. I also used it on my brother's 95 Corolla also with a rear main seal leak to no avail. I tried two bottles (not all at once) for each of the car and saw no difference. Maybe it was because my car's leak was new when I applied the product whereas the other two cars have had their leak for a long time.I would still recommend this product. I am not saying it will work for all applications but it is worth a try. Best of luck to you and I hope you found this review a little helpful.

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.

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.

Have a small oil leak at the oil pan, only been a few weeks but looks like it is starting to decrease the leak.
