Wynn's Engine Oil Stop Leak - Prevents & Stops Oil Leaks - Restores Elasticity of Seals & O-Rings - Lubricates & Protects Engine Seals - Safe for All Engine Oils - 325ml

My daughter's 10 year old car developed a slight leak so I changed the oil, oil filter & drain plug although it appeared to be coming from above the sump. After all the above, it still had the same slight drip so put a can of this in & it's only been in a week but it appears to have solved the problem (fingers crossed cos I only bought her the car to teach her to drive in and she passed and wants to keep the car so I'm hoping it's fixed as I resent spending a lot on a nearly 11 year old car)

Good quality item does exactly what it says.easy to use and reduces any oil leakage on joints and seals

Easy to use , no issues

Much to my amazement it’s worked on a leaking crank seal on a diesel Mini, It took around 300 miles but sorted !

21 year old car with a small but persistent oil drip, somewhere round rear of block where really hard to find. Tried this just to see if it would help. Dumped old oil, put this stuff and and then refilled with oil- just to be sure I wasn't overfilling. Drove a good few miles as the instructions do say it can take 200 miles of use to recondition seals. No dice, sadly. Seems unchanged. Some users have had luck, so it's up to you. At this price it has to be worth a try.

This stuff did work; I had oil slightly coming from the head gasket and was part exchanging my car, so I wanted to stop the leak and tried this as a long shot, and it worked so well. Obviously, this stuff is never going to repair a head for long, and to be honest, it could still be working now, but I part-exchanged the car a week later, so I don't know if it its still working but short term it was amazing

Easy use stops small engine oil leaks

Recently they changed its properties and it is now a very watery solution, which does not help at all as before. MOT failed. Last year when they had the thicker version, it was making my car run much better, less oil consumption but now this product seems useless. Changing brand, unfortunatelly

初めて入れた時はオイル漏れが止まりましたが オイル交換したらまた滲み出て来たので再度購入 まあ20年物の車なんで滲みが止まることを祈るばかりです

I applied to Peugeot 307 model 2007 and stops engines leak

Anche io come tanti mi sono dovuto ricredere. Ho prima di tutto fatto lavare in officina il motore, in modo da eliminare ogni traccia residua di grasso e olio. Poi, dopo avere fatto scaldare il motore per qualche minuto, ho versato il contenuto del barattolo dal tappo dove si versa l'olio ( per la verità ne ho messi 2 perchè il motore è un 3.000 cc V6). E' richiesto, come da specifica, di percorrere diversi chilometri prima che il prodotto si mescoli bene insieme all'olio motore e vada poi a raggiungere i punti dove si verifica il classico trasudare delle gocce di olio da invecchiamento. E' chiaro che il prodotto non fa miracoli, nel senso che se la perdita di olio da un dato tipo di motore è elevata, le cause sono altre ed il prodotto non serve proprio a nulla. Io devo dire che nel mio caso evidentemente sono stato fortunato, poichè dopo avere percorso ininterrottamente per 20 ore di fila, circa 2200 km, all'arrivo ho aperto il vano motore ed era completamente pulito. Direi prova pienamente superata.

Excelente producto sirve para colocarle cuando se hace el cambio de aceite de el carro

Lo he usado para una fuga relevante de goteo continuo. Según el mecánico perdía por la unión cambios y motor y desmontar para renovar... buffff. Así que probé esto y se ha resuelto por completo. No me lo esperaba perfecto, pero es que no gotea nada. No lo hagáis con el aceite usado ni en motores demasiado sucios por dentro o maltratados en el mantenimiento o no funcionará.
