It actually worked
Had a slight leak around timing chain cover.... put in the designated amount and under normal weekly use... I drive about 300 miles bi weekly... and there's no leak now..... I am no mechanic and I'm going off what my son told me was wrong... he also told me not to use stuff like this but decided to anyway and I'm no longer losing any oil tho I wasn't losing much to start... it does state its not intended for a big leak

Incredibly amazing stuff
I have had a slight oil leak that was seeming to get a little worse so it made me start looking online to figure out how to fix it. And that’s when I came across this and figured it most certainly cannot hurt to try….. and I am SOOOOOO THANKFUL AND HAPPY THAT I DID!!!! I no longer have any leak!!!! I have always heard people talk badly about this stuff and I am not sure why. All I know is, it worked wonderfully for my vehicle. Exactly as it stated it would. :) Thank you Bars Leaks for such an incredibly amazing product!!!!!

Good for sealso
Sealed my daughters literally empty crankcase. We put this in along with 4 quarts oil. Not an oil change it was simply running on oil film I thinkShe drove 2000 miles to Chicago and back and we then put 2 mote quarts in to fill up oil after she got back. Shop wants 2500.00 to fix. So maybe we will put this in every 3000 miles til she can get another car. Keeps u going a while longer at least

Useless product that doesnt work. Eyecandy earbait.
Hasn’t changed the leak at all. Made it worse if anything. Waste of money. Ridiculous warranty. To redeem the money back guarantee, you have to have a mechanic written note mailed to the company and then in 6-8 weeks, they will decide if you qualify for a refund. Nobody in their right mind is going to pay a mechanic $100 to write a letter for a $9 bottle of stop leak. I have a slow dripping rear main seal leak and have driven about 400 miles. I added half the bottle as recommended when I performed an oil change with thicker weight oil to further prevent the leak. Sprayed the bottom of the engine with degreaser and a pressure washer and today, I was under the car changing a slave cylinder and engine was still soaked with oil. Maybe even worse than before. THESE PRODUCTS DONT WORK. Learned my lesson.

My truck was leaking from the rear main and the oil pan. No longer leaks.
I highly recommend this product. I was losing over a quart a week and leaving oil slicks everywhere I parked. After about one hundred miles it no longer leaks at all.
