Had a small oil leaking on to my driveway for 6months and was told it was the main seal and it wound need to drop the transmission from the engine to change this $15 seal .....

Low and behold after a oil change and filter w/ 2 cans of brake clean to clean the under carriage the oil Leak stopped......Very impressive and it worked in my case,... 5 Stars 4 Sure ... show more

    • Noticeable!
Size: Pack of 1 Style: Repair
I had an oil change done for me back in February of 2023, in 2 months I burned and lost all the oil in my car and I run full synthetic 5W-20, which takes up to 3.4 quarts of oil to fill. I do have a high mileage vehicle but that is still a lot of oil either leaking or burning. I had to top off roughly 9 quarts of oil from February till my own oil change I had done in August of 2023. I used this product to see if there was any hope to slow down this problem of mine. And It sure enough did! , 2 months later I only needed to top off my oil about 1.5 quarts, when originally I was so low I had to fill'er back up to full in 2 months. If you are having similar issues or just noticing some oil disappearing , buy this product! ... show more

    • Seemed to help
Size: Pack of 1 Style: Repair
I was having to put oil in my car every month due to the oil burning. I used it and checked a month later and oil was still almost full and have not had to add much to it since I’m the past 3or 4 months. Was very surprised of how well it sealed and helped.

    • Best automobile product in a bottle ever!
Size: Pack of 1 Style: Repair
Faced with oil seepage issues in our two older vehicles, a 2001 E450 Super Duty and a 1996 Suzuki X-90, I had to decide how to address the problem associated with their age. I opted to use one bottle of this exceptional product in each vehicle, and I've been astounded by the significant reduction in seepage. Now, as part of my annual oil change routine, I consistently add one bottle to each vehicle. Both my garage floor and my wife are much happier for it! ... show more

    • Read the fine print
Size: Pack of 1 Style: Repair
I tried this on a 2004 Tahoe Z71 with 120k miles that had a rear main engine seal leak. It did not work and I thought I would utilize the full refund guarantee until I read the requirements of having a repair shop use it and verify that it did not work. Where are you going to find a shop that will waste their time to use this item? You’d have to make one up, so use it as a “Hail Mary” to see if it’ll work but don’t deceive yourself into thinking that you can get your money back if it doesn’t work. P.S. I work part-time at a repair shop and I won’t compromise my values to get back $15+ because of a gimmick warranty offer. ... show more

    • Ineffective for Craftsman lawn tractor
Size: Pack of 1 Style: Repair
Added this product as recommended, over time, and in successive amounts, hoping for the best...that it would live up to both the hype and product reputation...it's been 2 months now and the blue smoke issue has yet to cease, profoundly coming and going, unpredictably...this is after eventually having utilized the entire bottle...very disappointed, to say the least...one bottle should most certainly have gotten the job done...product performance is not as advertised... ... show more

    • Product worked Perfect on my 2012 BMW 750Li
Size: Pack of 1 Style: Repair
The product worked on a 2012 Bmw 750Li that was smoking when at a light, in traffic, or in line at fast food..... Was fine when diving as long as not at a stand still for over 3 to 5 Mins or stop and go traffic..... I fell like it was the valve seals leaking ao I brought this in hopes it would work.... The initial one I was going to try seems to stay sold out..... I decided to purchase before a trip that was 200 miles away to give it a chance to work..... I put it in the night before for 15 to 20 mins 1st and as always it started smoking...... On the trip back 2 days later before making it home we stopped at Zaxby's and about 6 cars were in line.... I say oh boy because it always smokes after a few mins in line soni have to cut the engine off and turn back on after a car move up..... But this time for the 1st time it did not smoke.... I was amazed and kept looking for the smoke but never came..... So the product works.... Dont know if it already worked on the first 200 mile because i did not test until i retured so I drove over 400 miles before i test it.... But no smoke at all...... Probably will cost over 5k to change all the valve seals if not more. ... show more
