Review: Works great for intended purposes. Disclaimer: producing miracles is not an intended purpose. - This product has been negatively reviewed far too many times, and I felt compelled to write a review on it. I have used this product on 3 cars with oil leaks, and my family has used it on their cars as well. My family has had great success with minor oil leaks, and 2 of my 3 cars I have used this on resulted in their oil leaks ceasing completely. My other car turned out to be a decent sized crack in my oil pan gasket, which explains why throwing some Stop Leak at it didn't solve my issue. This product helps greatly to repair old, hardened seals, but it doesn't falsely advertise to bring about miraculous results in moderate to major issues. My point is, this product works extremely well for it's intended purposes, and I feel that all of the negative reviews should be taken with an grain of salt. It would be spectacular to hear, from the negative reviewers, what sort of issues ended up being diagnosed in the cars this product didn't help. I'm by no means trying to put down the negative reviewers, but it does get a bit frustrating reading reviews on desertcart like "Put it in my car, didn't work, still leaking, crap product" or "I contracted a flesh-eating bacteria, and this 'highly rated' Neosporin didn't work. Don't waste your time. 1 star. Booooooo!!!!" Lucas Stop Leak is a great product for it's intended purposes, has been used and trusted by amateur and professional mechanics for years, and fully deserves a solid 5 stars. Review: Lucas Products Work Plain and Simple - I’m a Certified Auto Tech as well as Hyundai Master Technician with over 12 years of auto tech experience. I have seen it all used it all so many products claiming to stop leaks and improve fuel mileage and boost octane blah blah blah. Lucas stop leak actually works. Now you can’t expect it to work on a mechanical failure like rotted oil pan and broken gasket but it will stop or slow down seals and gaskets that are drying out or starting to fail. Most oil leaks are from going over your oil change intervals where the oil loses its additive properties and causes seals and gaskets to dry oil and crack. I find using Lucas stop leak with a decent high mileage semi synthetic or full synthetic oil is where it works best. Do not do what you could with older cars and use 10w30 or 20w50 oils thinking cuz it’s a thicker weight it will help. You will only damage your engine. Use the recommend viscosity or u can even go from a 5w30 to a 0w30. If in colder climates like myself in CT in winter I go with a 0w20 or 0w30 in my Acura with Lucas stop leak for better cold starts as this is wear most of engine wear occurs. So a thinner cold oil weight helps it circulate faster and oil pressure to rise faster protecting ur engines internals faster. With using Lucas I go 7500 miles on my oil changes on my 07 Acura TSX with 127k miles and the oil always comes out still clean a light brown. Had a small oil leak when purchased at 63k miles and has not gotten worse since the first oil change I did. I swear by Lucas products the fuel additive top end lubricant is also amazing and adds 2mpg on average to my gas mileage as well as a better cleaner running engine. ## Features - Compatible with petroleum, semi-synthetic, and full synthetic motor oils - Renews worn seals with no risk of damage or eventual corrosion - Reduces engine noise and oil consumption, while raising oil pressure - Contains no harmful solvents ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001KXN3YQ | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #10,459 in Automotive ( See Top 100 in Automotive ) #45 in Powersports Engine Oil #736 in Powersports Parts | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Compatible with Vehicle Type | Car | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 6,472 Reviews | | Global Trade Identification Number | 05014002120302 | | Included Components | 1x 1 quart bottle | | Item Type Name | oil stop leak | | Item Weight | 0.92 kg | | Liquid Volume | 1 quarts | | Manufacturer | Lucas Oil | | Manufacturer Part Number | 10278 | | Manufacturer Warranty Description | Warranty | | Model Number | 10278 | | Number of Packs | 1 | | Package Information | Bottle | | Size | Quart | | UPC | 049807102784 | | Unit Count | 32 Fluid Ounces | | Vehicle Service Type | Car | ## Product Details - **Brand:** Lucas Oil - **Liquid Volume:** 1 quarts - **Package Information:** Bottle - **UPC:** 049807102784 - **Vehicle Service Type:** Car ## Images ![10278 Engine Oil Stop Leak - 1 Quart - Image 1](https://m.media-amazon.com/images/I/61XY52k8MzL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Questions & Answers **Q: how do I use lucas oil stop leak?** A: When you change your oil put the stop leak Quart in in place of 1 of the Quarts of oil,then drive regular till next oil change.Unless your leak is extreme Lucas will stop the leak. I've used all the Lucas products for years in my cars and my 18 wheeler before i retired. Now i still use it in my personal vehicles. Love that Lucas! **Q: 2 questions: Does this need to be added every oil change like other products? Is it really thick like Motor Honey? Thanks!!** A: If your leak stopped then discontinue use, if you still have a leak such as from your main seal then you'll keep using this every oil change until either you die or your car does first. It fixes small and small medium leaks. If it's medium it helps but you'll need it every oil change and large leaks it won't fix. My rear main seal is leaking and instead of removing the engine to fix it I will be using this on every oil change forever. Best of luck! **Q: Can you use this on a Mercedes CLK320, 2004, and not hurt the engine?** A: The label says All engines. I have used it in a BMW 4.4 with no signs of any problems. Just don't exceed the 20% ratio of stopleak to oil. **Q: Can i use both this and the lucas oil stabilizer at the same time?** A: I pulled this info from the vendor.Use Lucas Oil Stabilizer in gear oil to stop leaks, reduce operating temperatures and increase the life of the gear oil. Since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, ATF and mineral oil. It keeps old engines alive and new engines new. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great for intended purposes.
