This really works.
I am astonished at how quick the leak sealer has worked on my car. I have a BMW e92 at 150K miles with n54 engine which is known to leak from the sump pan gasket on older or high mileage cars. The oil leak seeps down on to the catalytic converter and causes a strong oil smell within the car, particularly when pulling up at lights etc. Also makes a mess of the under tray which covers underside of engine and gearbox., and if left, drips onto the ground under the car. The pan gasket is a Labour intensive and expensive replacement at a garage and a complete pain if tackled at home for skilled owners (special tools required). I was a bit sceptical about how well the sealant would work, but considered it worth a try before committing to gasket replacement. Within a few miles of running the car the leak has ceased completely and the burnt oil smell has gone. Works on any rubber based seals on just about any car, so if you have a leak do give it a try. I am a time served auto technician and absolutely endorse this product.

Seal it before it’s too late.
Great little product to seal a rubber seals in the engine like the head gasket and sump gasket. You need 2 bottles over 6 litres. They tell you to add to fresh oil to get best results. You also need to have driven 500miles, yes 500miles for it to work. Have heard some people say it stopped leaks whilst car was stationery but everyone got different results. My sump gasket was leaking. 3 months on with 2 bottles used as I have 7 litres of oil capacity and 1,000miles later it’s still leaking, However it’s now an improvement of around 75% and that’s good enough for me. It’s pricey here in the UK and around $6-8 in the US. Not guaranteed to work on all motors but give it time and don’t push the vehicle hard whilst it’s doing it’s job. It’s saved me around £500 parts and £300 labour. Also I would have to buy 7 litres of oil too. So it’s a huge saving for 75% working.

Still a good product
My car was losing oil like crazy. I cange the oil and mixed the product with the new oil. Works like a charm since then, i check the oil every week and I’m impressed with the results.

Great for sealing
I have used this product for years. But very hard to get now. Custom issue now. But I use it to spray on car bushings and boots anywhere that rubber is over to wear and tear. It’s main use it to pour into your cars replace engine oil. This can stop seals leaking if caught in time.

Works for more than intended
THIS IS NOT MECHAICAL ADVICE! So I haven't really used this for its intended purpose. Came across these stop leak products in a Project Farm videos. Seeing how they work I'm nervous adding this type of product to oil but have found a different way of using it. Servicing tractors the manual fuel lift pumps hardly ever get used and quite often start leaking when you try to prime the filters, now tractor parts tend to equal EXPENSIVE. Several times I've found that using syringe with a thin needle to get a couple of ml of this directly onto (not into) the non-serviceable hidden seal has stopped the leak. I've also had good luck 50%+ using it directly on leaky hydraulic valves. This one bottle has so far saved me replacing around £3k worth of parts and there's probably 90% plus left

does what it says it can do
very wary of using these thing in my car engine but was told I had a small oil leak some where in the engine and could not find it used this stuff and no oil leak also seems to have made engine quieter

Can't say if it had made much difference
My Mk VI Fiesta has now done more than 100k miles. So it's kind of a no-brainer to do as many of the cheap things that would keep it running longer. Some of the slow oil leaks that bleed out around the lower engine case got my attention so I read up and found this. In contrast to replacing actual seals, this is a damn site cheaper - if it actually works. Thing is I can't really tell if it has. I've never had that bad of a leak so if anything I've maybe just reconditioned the seals a bit. My best advice is; if you get an oil patch under your car and the garage can't pin down where it's coming from or how bad - this might well be worth a shot. If it's just very slow bleed around the engine case but you don't see any evidence of drips, I'd leave it.

Worked like magic - immediately!
I had a constant drip from a newly replaced front-end crankshaft oil seal and couldn't face tearing it all down, redoing the timing, etc., to replace it again so I gave this a go. Within 10 miles the very serious leak had stopped and I now have no sign of leakage anywhere. Magic stuff!

EDIT: WORKED on my sisters 2010 Accord 2.4L rear main seal leak. The rear main seal was DRIPPING and was losing about 1-2L per day. I changed the oil and put this in and within ten minutes the leak slowed considerably. After a couple days the leak has 100% disappeared. It has been about two years and its still bone DRY. WOW, it really does work sometimes. Totally worth trying. My sister was so happy. didn’t stop my valve cover gasket leak... but when i took it off the gasket was literally as hard and brittle as plastic - it didnt even resemble rubber anymore due to the heat cycles its been through. However, I believe it slowed down or stopped my rear main seal leak since i dont lose oil between oil changes anymore. Its worth a try before spending 1000$ to repair a rear main seal. try to use it on a fresh oil change and leave it in for 6-8000km then rinse and repeat at most one more time. if it doesnt stop your leak after that (60$ investment) just get it fixed or live with it.
