It takes some time brother. Unless you have a catastrophic gasket failure, it does the trick nicely. Give it a couple of weeks of driving. I am a mechanic and believe that if it needs to be replaced, it should be. I do understand however, that on some cars replacing gaskets can be labor heavy and some people can not put the money into it. Some cars are not even worth the bill after repairs. Bottom line, I tell people that it is more important to keep the correct amount of oil in your engine. Some coolant stop leaks cause a mess thats hard to clean and can damage water pumps, as coolant is also the lubricant for the pump. This is a quality prroduct though!
So my 97 4.0 ranger has been leaking oil so I put a quart in and the next day let it idle for 5 hours , and by the end of that it was the equivalent of driving 100+ miles. It works like a dream . Every oil change I'm gonna throw maybe a 1/4 of a bottle in.
@07 grimdrummer Talk to your mechanic, idling is terrible for your cam. A Lexus may be less susceptible but I am betting there is plenty of plastic in your cam to wear and is far different from a 97, 4.0 Ranger which is all steel.
I’m actually glad I watch this because I put way too little in and I need to go add some more right nowWe’re supposed to get a blizzard about 6 to 8 inches of snow tomorrow morning.
Warm engine then pour at idle if not blowing by too much. I use a little bit on long parked engines to cling to parts. No dip stick rust. 20% is not nesessary. I up motor oil viscocity as miles pile on. Motor flush by 60000 and gas clean periodically. 3000 mile oil changes prevent carbon grind on seals and parts. Love lucas gas clean, oil conditioner and stop leak also. 4500 hrs on 2 generators so far. Slight smell, no smoke even at startup. New carb fuel systems.
I would think a “full review “ would include info on 2 days later and maybe 2 weeks later... I put it in a 98 ranger leaking into the #5 cylinder really bad and it worked very well. It would gum up a plug in 100 miles. I’m at over 500 and counting!!
Stop leak expands your gaskets. So if its valve cover/head gasket or oil pan gasket, it will work 1000 percent. Any other leak that is NOT a gasket it won't work
Most of the stop leaks on the market are not permanent as they advertise. They do work moderately maybe 50% reduction in about 3-4 days of driving. I've tried most from $5-$25 range
they say it takes 250 miles or up to 1 month for it to work properly. for more severe leaks you should use a bottle on 2 consecutive oil changes and they recommend using a quart on every oil change there on out. this may be true or may be a marketing strategy but I've used this product on multiple vehicles and had complete seals on all leaks. some for years and have sold the vehicles and know they owners of said vehicles and they're still running good.
I have a case of mild urinary incontinence so I took a tablespoon a day, it tastes like a slaughterhouse exploded in my mouth and gave me unrelenting nausea and diarrhea; the worst part of it is that it actually made the incontinence worse.
I guess there comes a point when the oil leak is so bad it needs to be repaired. I have a oil leak on one of our family cars. Been quoted an insane price by garage so much it’s more than the cars worth. So I’m going to try the lucas product. 🤞
Yes , fresh oil with this additive, run 3000miles and change oil again , after 500miles , should be see result , if not work , second bottle applied , if 2 bottle not work , you need to change the seal !
Concerning how thick it is: put the (clean, unopened) bottle inside a big pot of hot water for 15/20 minutes. Works wonders on changing viscosity and making it far easier to pour. I've had good luck with this product temporarily (2k miles) stopping a small leak from the oil cooler. It is, however, a bandaid, and not a long term fix. I like it for what it is.
let my car leak down a quart added half amount run my car half a quart or more on the low side stopped the leak run it a little low worked for me, oil was coming from the rear seal. I still run a little low no leaks.
What some people have said about switching to synthetic oil causes leaks. I believe that to be true and I was switching over gradually to hopefully not have a leak. At about 50/50 I developed a leak, so I tried this Lucas product (didn't really think it would work, but what the hell) and after a few hundred miles its looking pretty good. Don't know how long it will last? But for now i'm happy.
hey man how is your vehicle holding up today? i just noticed an oil leak after switching to mobil1 synthetic after roughly a thousand miles and im thinking of switching back to conventional and adding some stop leak
Have tried this as well but really not much change, replacing the main seal will be a pain but that's reality. Curious why you didn't put a piece of cardboard down instead of leaving big stains in your driveway? 🙃
@@ChadWilliamsFixesAll Did you ever find out what the root cause was? Seemed like a fairly decent leak? Also, how long apart did you use them? If it wasn’t extra time, maybe it just needed a little more than the instructions said to start.
This stuff absolutely works for small leaks. I used it once and started working immediately. I use it every 5000 miles with synthetic and never have any oil leaks.
You have to give it more than day.... it even says on the bottle to let it do it’s thing. I’m using it to stop a light burn of oil on my Volvo... Suspect valve stem seals and I have given it a couple of days and it’s not burning or leaking now as it was a little wet between the engine and transmission rear main crank oil seal...
I have a 2014 Subaru outback it doesn’t leak it just burns it out I know somethings up with the valves who knows just I know the motor sounds a lot better when I use this
Maybe it works for some but I've tried everything and just think all this stuff is nothing more than a witch doctor in a bottle... I've never had any max- life oil, high mileage oil or oil additive stop even so much as the smallest leaks. I resign myself to the fact that if you cannot live with the oil leak the only fix is to FIX IT.
I have a very minor oil (vacuum pump) leak. My oil leak is so minor it does not leave spots on the ground. I have a 2009 Volkswagen Jetta 2.5 SE. How much should I pour in using Lucas oil stop leak?
Actually it will not stop a big leak...just small ones around seals and such...there is no miracle in a bottle...but it works on what it says it will work on
Lucas claims you need to drive for 200 or 300 miles. Chad Williams didn't go that far as far as we know, so there is no expectation for his results to be accurate.
I feel you didn't follow instructions to a T. I got a 351 Windsor from 1988, and it leaked a quart a week. I followed instructions exactly and now down to 1 quart a month with droplets where there was puddles before
I've been a longtime user of Marvel Mystery Oil in my 1988 Toyota (quart of that plus 6qts Mobil High Mileage 10W40), but after 32 years and 315K miles it's starting to show a bit of age and I'm getting more oil in my PCV catch can than in previous years. New PCV valve and grommet reduced that so I know that was an issue, but I suspect (going to confirm whether or not that's the case when I do a leak down test) the rings are finally starting to show their age. There are a couple external leaks in addition to minor oil consumption, so I'm tempted to try a stop leak product. Been researching a bit now so it was good to see your real world experience with the Lucas.
@@EmTeeGee0610 as it turned out, my excessive oil in the catch can was from years-old sludge that had never washed out of the baffles in my valve cover, slowly preventing it from draining back down into the oil passageways. After a thorough cleaning inside and out of the valve cover, it takes close to two thousand miles to just get three fluid ounces of oil in the catch can, and I only show about half a quart low when I change my oil at 3K miles. Pretty pleasantly surprised for a 34 year old engine with now over 325K miles on it. Never even got to the point of attempting any stop leak product.
I used it in mine and within a few hundred miles, it doesn't leak a drop. It doesn't burn it anymore either. Best few bucks I've spent on a car. It should be called "liquid mechanic" Not for modern engines IMO. Mine is a 99.
I don't understand your comment you mean first we put lucas and drive 300 miles.you wanted to say that? And i wanted to know liqui moly stop leak is also work or not?
My engine has a very small leak too, not enough to even seep on the floor though.. Do you know if one needs to remove some of the present engine oil before adding the Lucas Stop Leak?
If it still leaks and its called STOP LEAK ,then ,no it didn't work. I think if you read the label, it says it doesn't work on all applications. Thats a pretty good leak. Hope you got it fixed.
I have a old 801 ford tractor that leaked oil every where!! Had to use 1 gal. Per. Hour to use to work. Had mechanic give estimate on repair. 2500. To 3000. Dollars tried the Lucas oil Stop leak Fixed my problem. Did have to use 2 ea. But 20 dollars was way less plus tractor is not down for repair!!
Nice video Chad... but how far did you drive after adding in the product ? It takes some miles for the product to do its thing... not sure your test was fair to the Lucas people....
You are absolutely correct. I haven't used THIS product yet, but I plan to. I've come to rely on Lucas products...and haven't seen any reason NOT to trust them. When it comes to a rear main seal leak...at SOME point, nothing in a bottle will fix it! "It ain't new but once!"😁
Try Blue Devil stop leak, I swear by that stuff after it worked on this car in my video you just watched. You can find the Blue Devil video on my channel!
it needs time to build up on leaks then it will block the leak eventually, but you could have a large leak that needs repair, that looks like a rear main seal.
I got oil leaks all under of my 318 and put that in , the oil leaks have stopped so far and my oil pressure is high agine . I'd try using another bottle .
Chad Williams yea think you are supposed to drive it around to about 100 miles so I don't know if you drive it to work or not but driving around more it's supposed to lubricate the seals and washers or gaskets and recondition them to new
Since putting it in, it has helped a little more with every mile I drive, but there is still a small leak. I am currently replacing the transmission, so hoping to find the leak. :)
Chad Williams Would this help with rear main seal leakage or oil pan gasket leakage? I just put new valve cover gaskets on my 99 Ford Explorer And it's still leaking
THIS STUFF DID NOT WORK. Not only didn't it work but it made the leaking worse. My car had a little leak, about 1-2 little drops a day. I tried Bar's Stop Leak (works for engine, transmission and power steering); after 300 miles, the leak was the same. I came back to Walmart to buy more, wm ran out or they were lazy to stock it up. I had to try Lucas and it's more expensive than Bar's and it said "really works". Now, after about almost 300 miles, my car leaks 4-5 drops just from noon to evening. DO NOT WASTE YOUR MONEY.
@@troypoland9047 who told you too much is worse than not enough ? That is baloney, friend. Not enough oil can lock your engine up in a heartbeat... too much oil isn't great, but it won't lock your engine up !
I put this in my Ford pickup. It did Not stop the oil leak from my crankshaft oil seal leak.wont use it again. If it say oil Stop leak that's what I expect.
It only conditions seals it don't stop leaks from seals that are actually damaged.... If you have a chunk missing from your seal of course it wouldn't work u have to pull transmission and replace those seals replace all while it's out...
My engine was already a quart low from the leak, so I didn’t need to remove any oil. But you never want too much oil in your engine. So, you may have to remove some if you are already full.
Please, do not trust this oil stop leak or any oil stop leak for you plane. I would suggest fixing the root problem and not trust any miracle oil leak fix. I would hate to see you have engine failures in the sky. So please, fix the root issue.
@@ChadWilliamsFixesAll Thanks buddy but I'm sure it's nothing a little flex seal cant fix that guy in the commercial put a boat together with that stuff
These are for small leaks example my car had a leak in the valve cover gasket put some of this in and it worked the leak got smaller and smaller and eventually disappeared had to put degreaser on everything and spray it off lol
Two things here; You would have to clean the engine at the time of the stop leak install otherwise residue would remain and fall, and second it takes time for any product to soften the seals. If you want to soften the seals real fast pour break fluid in it, however the seals would turn to mush shortly
Ah, glad I’m not the only one who recommends people who don’t like made for products to just revert to brake cleaner. If it doesn’t fix it, it will definitely make sure you replace it! 🤣
Can someone answer this please... Would this work to stop blowby past the piston rings as its a thick consistency...I would have thought it'd change the viscosity of the oil aswell?
Michael YZF Most likely, yes, to some degree. A better solution to that particular issue is most likely going to be the Engine Restore product in the gray can at WalMart and parts stores. It mixes thoroughly with the oil and fills the small inconsistencies in the cylinder walls similar to the way that silicone covers imperfections, but it does wash away with oil service if it’s not used regularly. I mixed the Lucas Engine Oil Stabilizer and CAR Products Engine Restorer religiously in every oil change, running conventional oil, in my ‘02 Mitsubishi, and I received nearly 50k totally maintenance-free, and the engine was cleaner than any other I have torn down when I pulled it for a rebuild. I got the car at 218k, built the motor at 265k, and the motor was almost as clean as a brand new, synthetic oil only, 50k-mile engine when you pulled the valve cover. Of course, I also flushed for a whole day with ATF before oil changes, so that probably had a lot to do with the cleanness. Picked up some MPG doing this stuff, too, but with 250k+ on a cheap Mitsu with 210k of unknown service history, there’s not much that can be done, same as my 300k Astro that recently blew a head gasket. Best we were able to get from the poor thing was 15mpg. Seriously, try that combo and see if it works.
You need to check oil level before adding it. You don't want to overfill or it can create leaks or worse. If your oil level is already full you'll have to remove a quart of oil before adding a quart if this. I would just remove a quart and a half of oil, then add the Lucas, then top off to the fill line with the oil i I just removed.
Had a golfball size hole in my block so you could say it was a pretty bad leak, this stuff did the trick reducing the loss from 6 quarts a minute to 5.5 quarts a minute
Wouldnt it have been SMARTER? to have put a towel on a cookie sheet or something flat to place under the car each time to catch the oil rather than mark up the driveway with oil spots that stay forever?
But it has been that big a deal to back the car up and let us see how much it leak after you put it in. I mean the other ones you always move the car for the last one you got to go under the car and we can't even really see.

Bro just remove the whole cap
Does the vehicle need to be a quart low on oil in order to use? I hate to add a quart of this to an engine that already has 5 quarts of oil.
I did that, is it bad ? lol
It was on a 1992 K1500 silverado.
Dont use it until your engine is a half quart low. Too much oil is worse than not enough
@@troypoland9047 I took out some oil and now it's a little above the line, about half an inch.
Do you think it'll be alright?
@@troypoland9047 who told you too much is worse than not enough ? That is baloney, friend. Not enough oil can lock your engine up in a heartbeat... too much oil isn't great, but it won't lock your engine up !
I put this in my Ford pickup. It did Not stop the oil leak from my crankshaft oil seal leak.wont use it again. If it say oil Stop leak that's what I expect.
It only conditions seals it don't stop leaks from seals that are actually damaged.... If you have a chunk missing from your seal of course it wouldn't work u have to pull transmission and replace those seals replace all while it's out...
Do you need to remove any oil out to compensate for the added liquid of the Lucas? Its almost a quart of Lucas....so do you remove a quart of oil??
My engine was already a quart low from the leak, so I didn’t need to remove any oil. But you never want too much oil in your engine. So, you may have to remove some if you are already full.
Stand the bottle in a bucket of hot water for a while it then comes out easier...👍
I can apply this stuff without reducing the amount of oil on my vehicle?
Most of the time, yes, you should be ok to do so. Just check the dipstick level first too make sure you are not too full.
Hello, the oil drain stopping agent can reduce the oil leak from the turbo compressor
Take the lid off man😫
Totally will next time! I fast forwarded a lot because it took so long LOL
Some people warm it up a little bit to make it come out faster
Common sense
Chad Williams 😂😂😂
Does it work on worn seals?
Same experience with me. Not working~
Bicycle time.
IT'S ALWAYS HELP WHEN YOU GO2 THE GRADE UP ON OIL GIVE IT TIME
I was so skeptical using this stuff. Feels weird to be pouring a cheap bottle of sealant into the engine.
Will this work on my cessna 172 engine been flying around 8 months with a bad leak
Please, do not trust this oil stop leak or any oil stop leak for you plane. I would suggest fixing the root problem and not trust any miracle oil leak fix. I would hate to see you have engine failures in the sky. So please, fix the root issue.
@@ChadWilliamsFixesAll Thanks buddy but I'm sure it's nothing a little flex seal cant fix that guy in the commercial put a boat together with that stuff
lol With all seriousness, please stay safe up there! You fly a plane in the air, not piloting a flex seal boat in a calm lake ;)
@4:24 - it didn't work but it stopped the leak?! Either it did or didn't work!
These are for small leaks example my car had a leak in the valve cover gasket put some of this in and it worked the leak got smaller and smaller and eventually disappeared had to put degreaser on everything and spray it off lol
You think I’ll stop a leak on valve cover of 2012 Chevy crize
If it is a valve cover leak, I would say to just replace the valve cover gasket. I have a video on my channel on how to do that repair.
You need to drive the car couple days before than the aditive works, is not immediately.
Funny how long did it take so long but it’s means it’s a good product
Two things here; You would have to clean the engine at the time of the stop leak install otherwise residue would remain and fall, and second it takes time for any product to soften the seals. If you want to soften the seals real fast pour break fluid in it, however the seals would turn to mush shortly
Ah, glad I’m not the only one who recommends people who don’t like made for products to just revert to brake cleaner. If it doesn’t fix it, it will definitely make sure you replace it! 🤣
Can someone answer this please... Would this work to stop blowby past the piston rings as its a thick consistency...I would have thought it'd change the viscosity of the oil aswell?
Michael YZF Most likely, yes, to some degree. A better solution to that particular issue is most likely going to be the Engine Restore product in the gray can at WalMart and parts stores. It mixes thoroughly with the oil and fills the small inconsistencies in the cylinder walls similar to the way that silicone covers imperfections, but it does wash away with oil service if it’s not used regularly. I mixed the Lucas Engine Oil Stabilizer and CAR Products Engine Restorer religiously in every oil change, running conventional oil, in my ‘02 Mitsubishi, and I received nearly 50k totally maintenance-free, and the engine was cleaner than any other I have torn down when I pulled it for a rebuild. I got the car at 218k, built the motor at 265k, and the motor was almost as clean as a brand new, synthetic oil only, 50k-mile engine when you pulled the valve cover. Of course, I also flushed for a whole day with ATF before oil changes, so that probably had a lot to do with the cleanness. Picked up some MPG doing this stuff, too, but with 250k+ on a cheap Mitsu with 210k of unknown service history, there’s not much that can be done, same as my 300k Astro that recently blew a head gasket. Best we were able to get from the poor thing was 15mpg. Seriously, try that combo and see if it works.
can I pour this inside the tank while I still have some oil?
You need to check oil level before adding it. You don't want to overfill or it can create leaks or worse. If your oil level is already full you'll have to remove a quart of oil before adding a quart if this. I would just remove a quart and a half of oil, then add the Lucas, then top off to the fill line with the oil i I just removed.
Had a golfball size hole in my block so you could say it was a pretty bad leak, this stuff did the trick reducing the loss from 6 quarts a minute to 5.5 quarts a minute
Wouldnt it have been SMARTER? to have put a towel on a cookie sheet or something flat to place under the car each time to catch the oil rather than mark up the driveway with oil spots that stay forever?
You are not wrong... took quite a bit of work to get all those stains out.
Use a little gas it comes right off
@@BlueByStereo gas will destroy a paved driveway.
Boots and kitty litter, works just fine! Thanks for the vid.
Chad - you say it worked but didn't stop the leak. Isn't that a contradiction?
It takes up to 200 to 300 miles to work...😉
Castrol 20/50 oil change might work.
Bro, that leak isn't being fixed by a fix in the bottle. That is a BIG and fast leak.
Did u pour whole bottle?
Yep! Sure did.
My review: 4-8 small drops leak each night before use. After use- 4-8 small drops per night. Doesnt work for me.
Jeff Beagle try AT -205 reseal
Take the cap off the bottle....goes faster.
lol yeah I was going to say …
But it has been that big a deal to back the car up and let us see how much it leak after you put it in. I mean the other ones you always move the car for the last one you got to go under the car and we can't even really see.
Blue devil dotes work or at205
don hezca I tried but it didn’t work on my vehicle 2008
I guess it depends on the severity of the leak.
You're not wrong!
Can use for petrol engine? Please reply me.
Yep, you sure can!!!
Yes comrade
Would this work on my crank shaft seal oil leak
Hey Joshua, this may help, but I would recommend Blue Devil Rear Main Stop Leak over Lucas. Blue Devil is amazing!!!!
@@ChadWilliamsFixesAll thank you so much
I gave up,10 min to empty one small bottle.....
No substitute for maintenance and repairs. I avoid "Miracles in a bottle" like the plague.
Informative! Thanks for posting.
