So, 800 miles in and the leak appears to be gone. I cleaned the area prior to adding the product on the next oil change. I have re-inspected several times and there is zero sign of leaks. I have to say that i was skeptical but it appears to have worked. It is very thick so pack some patience when pouring it in the motor. I just stood it up and walked away.

My snowblower developed a terrible rear seal leak last winter. I decided to try the Bar’s Leak Engine Repair instead of tearing down the engine and replacing the seal. I had all summer and ran the blower many times. To my surprise, absolutely no more leaking anywhere on the engine! It works as advertised.

After adding this product to our engine, the dripping oil (evidenced by the size of the spots on the ground) lessened significantly, though not entirely. Hard to quantify exactly how much of a difference it made, but I suppose every little bit helps!

My car leaks oil, this stuff definitely helps with that. Granted it is not a perfect solution to the problem but it's a much cheaper solution than getting a new engine for a car that I do not plan on keeping for much longer. This also stopped smoke coming out of the exhaust. I recommend using 1 or 2 applications immediately AFTER getting an oil change.

I have a 2002 Dodge Dakota w/ the V6. The check engine came on, the code said the #4 cylinder was misfiring. It has 142,000 mi. on it. so I took it to the shop. They put new spark plugs, wires and distributor cap on. that didn't work. He checked the compression it was acceptable (125 psi.) he checked the injectors and the were good. The check engine light still came on. So I did a oil change and added a bottle of Bar's leak 1000 engine repair. I've put on just over 200 miles and the light has…

I'm a bit surprised at how well this product works. I've used many other stop leak products in the past, but none have ever worked this well.I recently bought an older truck that I soon found out had a significant oil leak coming from the oil pan. The truck needed an oil change anyway, so I drained the oil, dumped this stuff in, and refilled the oil reservoir. Started the truck up again, let it idle for a few minutes, then walked away. The oil leak (which was a very significant leak) was…

i added this at the last oil change interval. who knows if it actually works? i'm hoping its at least doing something good inside the motor.

I ended up cancelling my order bc I found it at Walmart for half the price but the product is great, does exactly what it supposed to do. I used it with oil change for the notorious 2.4l ecotec oil burning issue. The burning has stopped or at least slowed dramatically, in addition to quieting the light ticking sounds.

I got this too possibly help with, the black smoke (when I start the engine, and many, many times I had to even stomp on the gas pedal and hold it, before the engine would even turn over.Yes, I am well aware, of the possibility of being old gas.Why? This 2003 , 6.0 liter engine, has 34100 miles on it.I bought it used in 2006, at which time, we lived on a mountain ( but my work was 35 miles away, and I averaged 60-80 hours a week working).Not much time left to do things with my truck.It’s real…

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…

Worked as promised. Just dropped the whole thing in my JD Kohler engine, which would billow out white smoke when under duress. Now it runs clean all the time.

This product seemed to increase my leak for the first day. Then slowed it over the following week. The leak is now nearly back to what it started at several weeks after using. It seems like a some win and some break even product. It did seem to increase the power on acceleration and decrease engine noise when idling. Good price for the product. If you have a leak and do not want to pay huge repair costs, it's worth giving a try!

Stopped all leaking from an old worn oil gasket for a few months then the leak resumed. It might have been the temperature change from spring to summer, but it didn't last very long. At least the leak is still slower than it used to be!

After letting my 20HP 50 inch riding mower sit unused for a season it appeared to have the piston rings stuck due to oil smoke and dripping oil coming from the muffler during and after operation. I measured the proper amount of Bar's engine repair to the mowers oil quantity and let it run. Within 15 minutes the problem went away, and now it runs like new. This stuff works!

PRODUCYT WORKS WELL IN 2007 SUZUKI XL-7 WITH 200,000 MILES ON IT. I SEEM TO GET ABOUT 1.5MILES MORE PER GALLON AND THE CAR BURNS LESS OIL. I USE THIS WITH SYNTHETIC OIL.

Restore brand engine restorer worked much better for my car to a this did. This made my car’s engine feel a little weird and sluggish. Restore doesn’t ever make my car feel like that, much better product than this in my opinion.

Bar's leaks is a great product that works as claimed. Stopped the smoke from my car's engine quickly. Just add to your oil and drive about 100 miles for it to work. Very pleased.

did not work for vw tiguan check engine damege oil separator and pcv valve have to remove the oil and put new oil garbage product

Took our leak away in our 10 year old minivan. But after a year or so the leak has come back. Not a permanent solution, but does work.

I used this on a 2004 chevy cavalier with 174k miles. It was burning oil at about 1/8 of a quart every 1000 miles. I put this in using some high quality high mileage synthetic oil, and damn! What a difference! The car runs way better, has a drastic pickup speed, and seems to get a bit better mileage.I wish they made a product for every fluid in a car! I would buy a break repair if they made it in a bottle!
