Stop Leak Products: AT-205, Lucas, Bardahl, Liqui Moly, Bar’s Leak, Lubegard, Hapco, Blue Devil, XADO, Seal Lube, CD-2, Justice Brothers, Wynn’s. Do "Stop Leak" Products Work? Do they cause damage to engine seals? Will they destroy an engine? Stop leak products compared for their ability to condition or soften hardened rubber engine components, impact on new rubber engine parts, ability to resist evaporation under normal engine operating conditions, and film strength or the ability to lubricate engine components. I buy all of the products and the supplies used to perform the testing to ensure an unbiased review. So, thank you for supporting the channel!

The Barr’s main seal works great on my gm5.3 gxp which I bought super cheap because of minor to medium oil leak s . Bought mint 2006 black gxp for $ 1200can because of minor and medium oil leaks and a few other problems . While doin mini restoration I added the Barr to fresh oil change started the car several times while repairing brakes ,minor paint touch up , polishing repairing multi purpose signal indicator , heads up display , replaced rad , oil undercoat . The Barr stopped all my leaks after I ran the motor for 30 min shut it of then started the next day 30 min It needs to run and cooled down couple cycles to work then every oil change add 1/2 the bottle

Great video. I've used At-205 in 3 occasions where I didn't want to deal with a complex assembly that was leaking and all 3 times it completely stopped the leak. One of them was on a lawnmower that was not all that complex, but not worth my time to mess with. It was leaking like a pig, I poured this stuff in thinking I just wasted 20$, there's no way it would do anything. And to my amazement I was wrong, it completely sealed the leak and when I sold it 4 years later, it was still running great and dry as a bone all around the base where it was leaking originally. This stuff truly is amazing.

Having worked as an installer, there's so many variables, not only concrete prep and measuring and mix ratios, but temperature and humidity on the day the product is poured. While a test of this kind might slightly show an advantage of one over another (though they all basically use the same chemical ingredients) it's unlikely to have any bearing on how it will actually hold up for an individual at their particular garage.

Add sand for slip resistance so delete that factor and just test the product but the best bet is to prepare the surface extensively and almost any product will work better. Best result pour a new slab and then apply product with a handful of sand. Idealy fine quartz. Just realise you created sand paper of the highest quality. You are welcome.

@@ItsKing32 HAHAHAHAHA You are kidding, right? I mean, comon. Today's cars (other stuff is basically the same story) are designed in such a way that you need to bring it to the repairshop because of special tools, or because it is just a huge job to take it all apart. John Deere is making sure Farmers are no longer able to repair their own tractors. Because of the new technology they put in these machines. And so: This man may think about his design...... but when the big guy who pays the money says it has to go his way, it will go his way. And so, you can design a car to last for ever (like they actually tried back in the early days, hence why you can still see such cars driving on the road today), but there is no money to be made if the customer is never going to need any repairs. And so: Not a valid way of making money. And so: The engineer may be Einstein for all i care. He will still be employed, getting his money from someone else. And the one who pays is the one in charge. Not the engineer. Otherwise, great tip. Wish people would give it a bit more thought before we all accept nonsense like we already have accepted the nonsense. Take this last example: Plastic Intake manifolds. PLASTIC INTAKE MANIFOLDS. To save costs they came up with the idea to make such parts out of plastic. It is bolted to a hot engine. Guess how long it will take for it to become bad, how long it will take before you need to replace it....... and guess how much work it is to replace it...... Meanwhile cars with METAL intake manifolds NEVER have to replace their intake manifold. And: We all accept such rubbish. I dont see people protesting infront of the factories, do you?

Great and informative stuff, as ever. As you said yourself, it seems like the products which work best to restore rubber seals, do so at the expense of reducing the lubricity of the oil. And those which don't impair the oil's lubricity are the least effective. I'm wondering how long the beneficial effects on the rubber seals last. ie. could you run the stop leak for a few hours/days/whatever just to fix a leak and then do an oil change to clean oil again?... or do the stop leak products need to stay in the oil, for a repair to remain effective? In other news, a suggestion: How about a test on engine flushes?

I used the at205 for a leak in the rack and pinion of my truck and it worked amazingly and didn’t leak a single drop for about 3 months. The leak has come back now but it was such a significant leak to begin with that I’m surprised it did anything at all, plus it gave me more time to save up some money to actually fix the problem

All of these tests are kinda pointless because not one of them is being done at the manufacturer's recommended concentrations. Not one of the instructions say their products should be a 50/50 mixture with motor oil. Another problem is the tests weren't long enough, though to be fair, this is much harder to replicate. 2 hours is equivalent to maybe 140 miles (2 hours at 70mph) I suppose the tests are still fun, but they really aren't telling anything.

The only concern I have is the 50/50 mix you used. I feel some of these performed better or worse because there was an unrealistic proportion compared to the oil. Unless it specifies 50/50, I feel this deserves a revisit with the proportions correct, at least for the wear and heated oring test
@Papajin68
@Papajin68 Год назад
Agree -- If your percentage of product vs oil is greater or lower than specified in the directions, then you're not really testing the recommendation from the manufacturer. I guess you could make a point that this shows an exaggerated view of what would happen even under the specified mix ratio, but now It's hard to determine if the differences would be significant enough to worry about when using the correct ratios.
@Voyajer.
@Voyajer. Год назад
The 50/50 mix is useful for comparing the differences between the frictions of each product and isn't meant to be indicative of how it would change wear in an engine. I would like to see the proper mix ratios in addition for a closer analog to any sort of engine wear.
@Papajin68
@Papajin68 Год назад
@@Voyajer. The same could be said for nearly all the tests. Flow characteristics could change significantly if the ratios are incorrect. Same with the ability to swell the seals... if you're mixing the product at a higher or lower ratio than the manufacturer specifies, you may see better or worse results during testing making it hard to say if one product is actually better than another in any of these areas. I don't know enough about the subject to know if swelling an o-ring too much which might cause issues, or how soft is too soft for a rubber gasket or if there is such a thing. People use these tests to pick a product to use, and if the recommendations from the manufacturer aren't followed as closely as possible, you're introducing new unknown variables to the mix which may invalidate your results in real world conditions. I think all the tests themselves are reasonable, they just need to use the suggested ratios so we're comparing all apples to apples rather than a pea to an apple to a watermelon.
@DanielRichards644
@DanielRichards644 Год назад

The most hilarious thing about snake oil is that the original snake oil actually worked. It was oil made from boiling a Chinese water snake that had some manner of pain relieving chemical in it. Of course, people wanting to market it in the U.S. didn't have access to a snake that was indigenous to China, so they used whatever snakes they could find, then eventually realized that since none of the snakes here had any therapeutic value when boiled down for their oil, they just started selling cheap mineral oil and calling it snake oil, and instead of just claiming it could relieve joint pain, claiming it could cure just about anything.

I had great results with AT-205 on a old lexus where the engine seals we were starting to leak (as in a few drips overnight in the driveway). I added a bottle AT-205 before an oil change with about 5 hours of cumulative driving time per the directions followed by an oil change and that was over 2 years ago with no leaks since from the seals since. I highly recommend AT-205 if you catch the leak early enough. It is also important to not let the stuff sit in you engine forever. You need to change the oil after the 5 hours of cumulative runtime. I also changed the oil at 3000 miles vs. the normal 5000 for the first 2 oil changes to make sure it's really flushed out. I'm back to 5k intervals again or 6 months whichever comes first (always with full synthetic high mileage for cars over 75K). Always worth a try when the proper fix would have cost in the thousands.

Do you know how long the change lasts? I'm wondering if I can treat it once, run the engine for a short while, then change the oil. I want to avoid the wear with the AT-205

@@jeremyvalero-Sapphire You have nothing to worry about. In the test he did above he did a 50% motor oil / 50% additive mix which as absolutely ludicrous and virtually meaningless in real world conditions because the RECOMMENDED amount of additive added to the motor oil is nowhere near 50%! In the case of AT-205 the recommended amount to add is 6 ounces! That's a TINY fraction compared to what was done in this video! That equates to about a 4% ratio versus the video test which was a 50% ratio which again, makes the wear test done in the video virtually meaningless and very misleading. What would have made sense was to do that test BUT going by ratio stated by each product manufacturer since that is what people will actually be going by when they use it in their car. In addition to this, both the AT-205 and the LubeGard Seal-Fixx are known for being so effective that users of the product actually recommend that you start with HALF of the dose mentioned in the instructions so we're talking about 3 ounces, which again, its a TINY amount compared to how much motor oil it's being added to! The ONLY reason you saw increased wear in the test done in the video was because of the ridiculous amount of additive he added to the motor oil, which diluted the motor oil by half! Of course that's going to increase wear at that dilution since the additive is NOT a motor oil! But at between 3 to 6 ounces per 5 quarts of motor oil there will be no increase wear for goodness sake!

The tests you come up with for these things are amazing and I appreciate the lengths you go to. The ATP stuff is great for swelling seals and spraying on suspension bushings or anything rubber but I wouldn’t put it in my engine. Ive used Lucas products for years and they are great for many uses. It will usually slow an oil leak really well but doesn’t typically stop it entirely. I use a quart of Lucas in every engine I have and we’ve used it at our shop for many years, it’s the best oil stabilizer/additive there is imo

@@All-about-everything It would be good in any higher mileage engine, the only things I would maybe not use it in is newer engines that require very thin oils. It could make the oil too thick to get through some of the small passages modern engines have. Some cars take 0w oil now and you can’t even use 5w in some without potentially causing damage. Literally just about anything else tho, Lucas is pretty great in. Their power steering and transmission fluids are also awesome and I’ve seen them keep cars going for a long time.
