It's worked well for me in the past. No stop leak will stop all leaks, but's stopped most for me and substantially slowed down others. Of course fixing the cause such as worn gaskets is best, but that can be quite costly for some cars.
I have an RV that blew out oil smoke every time that I started the generator. The generator only gets used once or twice a year but I try to stat it up every month for a few minutes. I tried Lucas and ran the generator twice for about 15 or 20 minutes. It didn't seem to do much at first. I ran it again and forgot that it was running, it ran for about 4 hours. I started it up today, Lucas stop leak has been in the engine for a month now, not a single puff of oil smoke came out on start up. This is great stuff I would recommend it to anyone that thinks that their value seals are leaking.
If you have a Valve Cover leak i Recommend you Tighten up the Cover it Will stop the Leak, but if the leak comes back You should change the Valve Cover Seal 😊
I have a leak that I believe is the rear main seal on a 1997 Chevy C1500 with 350. Put some of this in yesterday so we'll see how it does. update: Sorry for not updating sooner! It's still leaking. I may pull the cover off and make sure the rear main seal is the issue an a few weeks when my wife's out of town and I can take it off the road a few days. In the mean time I'm going to try some AT-205 since I can find some now. It's kinda what I wanted to use in the first place but no one had any until recently.
@@chrisg9926 I'm not good about checking the oil because I don't drive it much, my wife does and she doesn't put a lot of miles on it. I told her I was putting it in but haven't gotten any feed back from her. I'll make an effort to check it out and ask her as see how it's working and let you know.
I used it in my 06 Subaru Impreza. Very small leak that the drops didn’t make it to the floor, just the exhaust so it smelled! Stopped the leak in 1 hour of driving but the leak came back a week later. Will try again with the next oil change….
BEST Cheap oil leak fix: Add Dot 3 brake fluid to oil anytime you have a seal leak(not gasket unless it is rubber). 15-20 drops per 5 quarts. Run for a few days, no more oil leaks.
Is this true? Don’t want to blow up my wife’s engine trying it out if it’s not safe lol at least if that happened I could finally get her to get a new car so I can stop fixing this one!
All your doing is making your seals swell. It will work temporary, until the seals swell and break. There's no miracle stop leak... you need to fix the issue unless the vehicle isn't worth it
Any issues with this stuff? I have a few oil seepage points (im not losing a noticable amount) on my 05 silverado. I'm just hesitant with using this stuff because of how thick it is, but I'm sure it'll just blend with your regular oil.
@@Mr.G626 yeah try it out this morning .... after a bit my car started to smoke ( i was scared a bit lol ) but i let it cool down after and it dosent smoke anymore so ... so far im happy with it
If you are close to an oil change, then you should change it first and then add the additive. You will need to add the stop leak every time you change your oil. Great question!
@@ScottsGarage17 ... oops, I had oil change yesterday and put half quart of Lucas Stop Leak then 4.5 qt of Castrol high mileage 5w 30 ... i have a 99 accord EX 4 cylinder which takes 4.5 to 5 qrt of oil. So what happens if you put the Lucas before the oil ?
Thank you for the video. Since this product is thick, does it matter if I add this product BEFORE or AFTER pouring in new motor oil during the motor oil change?
Our country have i can't purchase lucas My Truck have leakage engine oil can i use liqui moly product i wanted to know liqui moly product also work like that please advice me anybody.
I’m not sure of what kind of leak I have I suspect it’s pretty bad i can smell the burning oil after short distances also I see small amounts of smoke coming from the engine do you think this product will help or is the problem to severe? Please help
@@ScottsGarage17 depends, that to me sounds like his rocker cover is leaking, so oil is dripping down onto his engine block and burning, which would in turn release a small amount of smoke.
@@ScottsGarage17 yeah your right because i just bought and test it out and anyway for me it works good and yes after let the car cool down but instruction are good i did follow them and my car dosent smoke anymore
I'm your subscriber from Indonesia. I want to consult about lucas produck. 1. Can this Lucas Poduck stop seepage in the rear crankshaft oil seal and oil filter gasket? 2. Lucas is only used once or must always be used every car engine oil change. 3. Is it true that this Lucas product, if I study it, seems to increase the viscosity of engine oil? Thank you, please return the info.
I use this product in my jeep and I still waiting for the stop leak I don’t know when but the only thing I know this product is not good don’t spend your money
No it doesn't work. It slows down the leak but doesn't actually stop it. I'd rather spend $50 to $100 on the part and then fix it myself. Then to spend, $15 on some bullshit that don't work. $100 is less than $15. Tell me I'm wrong. Cuz that only slows it down which still isn't good for the engine cuz it's still leaks causing engine problems. And then that $15 fix ended up being $2,500 repair. So $15 is more than $100. It's better to buy the part and just to fix the issue then to buy some BS that don't even work half the time.

Good video Scott. Did you need to take a quart out before adding a quart of this stuff?
It does say replace one quart of oil with the Lucas.
Thank You 👍🏼
So do I want to just add not to remove some oil from engine?
I will try this in my honda city z even the engine is no leak prevention for small leaking, is this good pls advice me thanks
I got an oil change about 15 days ago can I still add the Lucas or do I have to add another bottle of oil
How long does this last

jas it works well - no issues.
@@ScottsGarage17 ok thanks. New subscriber here btw lol
@@Mr.G626 yeah try it out this morning .... after a bit my car started to smoke ( i was scared a bit lol ) but i let it cool down after and it dosent smoke anymore so ... so far im happy with it
but what can it do to an engine over time? can't be good for the inner workings.
No it’s 100% petroleum it’s not gonna mess up the “inner workings” 😂
Thanks!
Dumb question but should you do an oil change an top it up before adding, an does this help with head gaskets thanks all
If you are close to an oil change, then you should change it first and then add the additive. You will need to add the stop leak every time you change your oil. Great question!
@@ScottsGarage17 awesome thx ya I couldn't find the proper awnsers an the label doesn't explain much thanks again

So what happens if you put the Lucas before the oil ?
@@jcorral2 it doesn’t matter if u put it in before oil or after oil it still works
hey. I have a question. if its time for an oil change do you have to buy another bottle of lucas?
Yes, that is right.
Thank you for the video. Since this product is thick, does it matter if I add this product BEFORE or AFTER pouring in new motor oil during the motor oil change?
I don’t think it matters.
It's better to mix it in with the oil then applied... Otherwise it'll mostly sink to the bottom of the oil pan
Good video. May I ask who plays that background music?
Will this Lukas stop the leak going into the spark plugs
Just got a bottle. We will see if it helps.
Did it help you ?
@@MrBanex25 Yes, Sir. I was probably adding a quart per week and it seems to be holding now after about a month.
@@texasRoofDoctor Great, thanks for letting me know
If my oil level is full can I still add this or must I wait untill I'm diwn a quart of oil?
wait til you down a quart. Or sub a quart of this on your next oil change
does my car have to be warmed up before i put it in my oil ?
Our country have i can't purchase lucas
My Truck have leakage engine oil can i use liqui moly product i wanted to know liqui moly product also work like that please advice me anybody.
Subbed 👍🏽
This is same as stp stop leak and engine oil treatment of cyclo its sticky
Do you have to re-add this again if you have the oil changed down the road ? Thanks
Yes you do.
I’m not sure of what kind of leak I have I suspect it’s pretty bad i can smell the burning oil after short distances also I see small amounts of smoke coming from the engine do you think this product will help or is the problem to severe? Please help
It sounds like your problems are more serious, perhaps worn piston rings. Stop leak is more for oil drips.
@@ScottsGarage17 depends, that to me sounds like his rocker cover is leaking, so oil is dripping down onto his engine block and burning, which would in turn release a small amount of smoke.
Sir good evening... After filing up the Lucas Stop Leak you just let your car sit in your garage sir.. Pls advise
Jose Yu you need to operate your engine for the Lucas to mix with the oil to stop leaks.
@@ScottsGarage17 yeah your right because i just bought and test it out and anyway for me it works good and yes after let the car cool down but instruction are good i did follow them and my car dosent smoke anymore
Is it okay to use this stuff on a 98 Honda Accord with high mileage?
Yes this stuff actually works as 2 things a oil thickener witch helps from engine wear and helps stops leaks

wow
Do you add the whole bottle to the engine?
Yes
I heard oil stop leaks can plug oil pathways and burn up your engine, any truth to that?
It doesn’t work

Poor audio, can not hear
No u are just old.
Lucas makes something for that too
