I pretty sure it does what it says on the tin
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)

Easy to use and works on micro leaks
Used this before and found it worked. This did the job again until I had the time to repair the leak properly. Easy to use. Pour it in and off you go.

Take your chances.
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.

watery solution, it does not help
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

Messo in un motore benzina aveva qualche leggera perdita di olio motore, sparita completamente problema risolto

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.
