I can't believe what Bars Stop Leak did for my engine! 

Tell us your experience with Bars stop leak, it really helps others that need to know. Taking time from your day to help someone really shows kindness.

I had a rear main seal leak once, pardon my description, but it was pissing oil…used this product and it went from a serious leak to barely a sweat of oil. For me it gets a 👍

A good test would be to see if the seal that hardened in the cofee pot can be restored to soft if bathed in the stop leak fluid.

i have used this stuff for 60 years also radiator sealer this stuff works just takes time!!! will not fix water pumps shafts spins removes sealer use low pressure radiator if you sealed antifreeze terrific video thank you!!!!!

Yeah Nathan.. I remember maybe 50-60 years ago I've used Barrs Leak in my Radiator..(it worked as well as lubed the water pump) Not exactly the same but you would think they would have improved their name somewhat in the last half century. Thanks Nathan.. Cheers 🥂

cant speak for the engine stop leak...but I used the Bar's for power steering and it fixed my SCREAMING steering pump issue :) best $11.00 spent on additives so far.

It does work. I’m using this to buy time until it’s not 100° outside and I can get this fixed myself. I don’t want to be repairing an oil pan leak when is 98° outside

On old Chevy small block V8s where even new rear 2 piece seals leak this works pretty well!

My mechanic told me my real main seal in my vortec 5.3 liter Tahoe (300k + miles) is leaking. When I got under it to change the oil a leak was evident. I replaced one of the 6 quarts of oil with 2 containers of Bars rear main seal stop leak. We'll see what happens. It's been about two weeks now and the leak has stopped, well see how long it last.

Long story short........My 2012 Chevy sonic w 138,500 miles started leaking just under from where I put my oil filter. It would slowly drip down to my exhaust and stink and smoke up badly. After trying Bars stop oil and seal leak with my oil change, I can say I noticed a 50 % less burn after a week or so. After about a month I forgot I had even had a leak. I have since changed my oil again and added another bottle. NO MORE OIL BURNING ISSUES FOR ME

Sounded like I was in virtual reality. Good test

I used this and about 3 week later my oil light comes on, I went to auto zone, got some more of the product and oil. I poured about a quart in pulled the dip stick and it was gummed up with the stuff on it, I thought it baked the oil on the dip stick, I cleaned it off and it felt like rubber. I just hope it doesn’t destroy my engine, going to pop the valve cover off and see if it’s still pumping.

I have never had much success with any type of stop leak. Power steering leaks for me have become worse. Cooling systems have become clogged. With modern engines with variable valve timing, they usually require a 0W something oil. Personally, I would not add anything thicker than the recommended weight oil. You could easily rob Peter to pay Paul. It would be much cheaper to slide a drip pan under the car and add oil when necessary than to replace the cam phasers/actuators or whatever the manufacturer calls them. On top of that, if the product doesn’t completely stop the leak, you still have a spot on your driveway so what’s the point? Do you actually know anyone who has collected any money for damages from a company that makes this type of product? I may be somewhat of a cynic, but I am leery of the long term effects. Sometimes the cure can be worse than the disease. I appreciate you, Nate! I’m just not a fan of additives, particularly stop leak products.

First of all with it being thicker changes the oil viscosity. I can see where that can slow the leak down. I like to see what the viscosity of that bars stop leak is.

Just put this in my 350 in my corvette after the rear main started dumping oil pretty good. Ran it yesterday through the day and didn’t leave more than a dime sized drop after the whole day

I tried this one and it didn't help so I used bars valve seal professional strength and notice better results

I have used Blue devil oil leak. I have used it on cars that have began sweating but not leaking. Works everytime and sweating pretty much goes away by next oil change

Since it changes viscosity can you use it on VVT engines? Those are supposed to be sensitive to proper viscosity

Its not my time to change oil but can i add this to my engine?

Nicely done video. Earned a subscriber.

Might have to try this, my 2012 Honda is daily driven and no leaks but I using HM Motor Oil

I just put a bottle in my old 1999 f150. I’ll get back to you.

Good video thankyou. 👍

Bardahl,liqui moly,gold eagle,atomex .which one that you recomend sir?is it really stop the problem or i should just change the gasket?thank you

are you in Kentucky?

Hi have you used atp205???

Would you use this for seal maintenance?

i used this on my 81 kawasaki kz 305 because i was getting oil on spark plug threads. after about 30 miles of driving it was gone. i use it for every oil change now

What if you left the paper under the car even longer? Maybe a bigger oil puddle?

Isn't this the same car you did the stop leak review/snake oil with the valve cover leak 1 year ago?

It would probably starve the lubrication to your camshaft and destroy your engine Just let it link on the driveway and use cardboard

Stop leak does not work good (or even not at all) with hyper modern rubber seals, the brown and blue ones are Viton or Neoprene seals...they are resistent. Stop seal works only with BUNA (synthetical black rubber seals = NBR) On vintage cars with rubber gaskets most stop leak additives work pretty well.

How long after an oil change can I use the product ?

This guys accent cracks me up. I didn’t know people actually speak like that . I thought Towmater was doing the voiceover 😂😂

I'd rather topping up the oil from time to time than using this stop-leak thingy at each oil drain interval.

Hello, my Pt cruiser doesn’t leave oil on the floor but it goes in combustion and makes blue smoke. Elastic bands problem. Do you think the product could help? Thank you.

Just pour it and left it off ? So it just sat there and didn’t move around ? Lmao no wonder it didn’t work. This stuff works very well.

Did you apply heat to the coffee pots when conducting your test?

NOTICE: He placed the new clean paper under the car and then drove off ???.....Vodoo camera work.

❤ oh yes

RISLONE.

All those types of additives do is clog and plug things up imo.....fix leaks the correct way and replace gaskets and seals.

Yeah sure mate .. wink wink 😂
