The leak stopped after about 100miles. I have a 2011 gmc sierra 1500 2011 with a real main seal leak and it stopped it Review: Read this if you are considering buying this product for an oil leak! - I'll start by saying this product goes against everything I believe or have been taught about internal combustion engines, the two most prevailing thoughts before ordering this were: #1: Only oil goes in the crankcase, nothing else #2: Snake oil does not work, especially for a long term solution, fix the real problem instead of throwing money and additives at the problem that ultimately may do more harm than good I have a small block ford engine that has a notorious rear main seal leak, drips engine oil right at the transmission bell housing. Started small and got worse. This is a well documented problem, and the transmission must be pulled to replace the seal. I have heard many stories of people who have replaced the seal, only to have the brand new one leak too, people have tried crankshaft sleeves to make the fit tighter, and with mixed results. I did not want to go down this road unless I had no other option. I did a little research on this product, and the reviews are mixed. I have not heard any horror stories worse than "it didn't help and I wasted my money on this product", and from what I understand it works completely differently than the "leak stop" additives you would use for a head gasket, coolant leak, air conditioning system leak, or tire leak. All the latter leak stop additives are adhesive products which are glues and materials designed to fill cracks/voids and cure on contact with air. This product works differently. This product is not an adhesive of any kind and does not leave any residue. It is basically a solvent that attacks rubber and causes it to swell. This makes the seals fit a little tighter if the only problem is a seal is a little old or dried out. If the seal is cracked, deformed, or a synthetic material that the active ingredient in this product doesn't react with (its designed for rubber, not corks, silicones, etc), this product will most likely not help. I dumped this in the oil reservoir. It was already a little low from the leak, so the excess oil in the crankcase was not an issue. Ran the engine for about 30 mins and no change, still same dripping while running. I drove the vehicle every day approx 30 miles. After a week, the leak was barely noticable, just the bottom of the transmission housing felt a little oily, but no puddle/stains in the driveway. After 2-3 weeks, the leak was gone. And I mean gone, not a drop. I was impressed how well this worked on this problem and thought it fixed it permanently. Then about 4000mi later, I did an oil change. For the first few hundred miles after that, no leaks, then after about 1k miles, I noticed the leak started to return. I immediately picked up another bottle of this stuff and dumped it in, about 1 week later, the leak was gone. I now don't even mess around anymore and just add a bottle of this stuff to every oil change, and it is under control, its a small price to pay (even for life of vehicle) to not have to deal with the rear main seal. For me, this product makes a night and day difference, I have been using it for approx 30k miles, but depending on the root cause of your leak, your mileage may vary. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00754T6TK | | GTIN (Global Trade Identification Number) | 00046087010402 | | UPC | 046087010402 | | おすすめ度 | 5つ星のうち4.2 2,829 レビュー | | パッケージ内に含まれる商品の数 | 1 | | パッケージ情報 | ボトル | | ブランド | Bar's Products | | ブランド名 | Bar's Products | | メーカー | Bar's Leaks | | メーカー名 | Bar's Leaks | | メーカー型番 | 1040 | | 同梱商品 | ユニット^取扱説明書 | | 品番・型番 | 1040 | | 商品の重量 | 1.1 ポンド | | 容器の種類 | ボトル | | 液体の容量 | 16.9 液量オンス | | 液体容量 | 16.9 液量オンス | ## Product Details - **GTIN (Global Trade Identification Number):** 00046087010402 - **パッケージ情報:** ボトル - **ブランド:** Bar's Products - **商品の重量:** 1.1 ポンド - **液体容量:** 16.9 液量オンス ## Images ![Engine Oil Stop Leak Pack of 1 1040 - Image 1](https://m.media-amazon.com/images/I/71BWlf2ZPcL.jpg) ![Engine Oil Stop Leak Pack of 1 1040 - Image 2](https://m.media-amazon.com/images/I/816-v04DEXL.jpg) ![Engine Oil Stop Leak Pack of 1 1040 - Image 3](https://m.media-amazon.com/images/I/41X0xUy+9EL.jpg) ## Questions & Answers **Q: Is this safe for diesels, specifically the Duramax 6.6L?** A: Yes..... According to Bars Product, this is compatible with all engines and engine oils. **Q: Can you use this with synthetic oils** A: Yes, I have used it with synthetic oil with no issues. **Q: What it does with my other gasket that has not have a leak?** A: If I'm understanding your question correctly.... you would like to know what effect this has on gaskets that are not leaking? The answer is nothing..... Thank you Eric **Q: Is this safe to use with other gas additives such as seafoam, lucas?** A: Yes there is no problem. This gets poured into your oil crankcase not into your gasoline. Seafoam usually gets poured into your gas tank to clean injectors and cylinder walls sometimes you can put it in the crankcase just about 4 oz to clean junk this does not stop any leaks usually done 100 or 200 mi before an oil change. Lucas has many products some that are injector cleaners that go into the fuel tank some that are oil stabilizers or stop leaks or friction additives that go into your oil crankcase you can have Lucas oil additive/stop leak and bars leak in your oil crankcase they don't interfere with one another ## Customer Reviews ### ⭐⭐⭐⭐⭐ It worked for rear main seal *by K***E on 2026年7月18日にカナダでレビュー済み* It blows my mind but it works.
