Rislone 4447 Compression Repair Fix with Ring Seal - 16.5 oz.

Purchased this in desperation as my motorbike had lost compression in one of its cylinders so it was this stuff or bike sold as spares and repairs . Used 3/4 of the bottle and the bike is running like new..... can't fault it!!!!

Great thanks

Seems to be working so good so far. I could feel a definite improvement with the compression and any smoke from the exhaust under load a acceleration also has stopped. How long it will last only time will tell.

It actually works so I'm well pleased

Was advised to use this by a mechanic for a worn piston ring. The car had beforehand occasionally smelled like burning oil. It took a few days to work - But no more burning oil smell. Chances are it'll pay for itself as I won't be refilling the oil so often.

WASTE OF MONEY !!! Car failed on emissions and blowing small amount of smoke from burning a little oil bought this, put it in and took it back to MOT and they've said its a lot worse now so it really doesn't work. The consistency is that of gearbox oil maybe a little thicker but I used gearbox oil in the past with better results than this.

Used this for the last 3yrs to help my 22yr old Mercedes engine, improved compression and quieter running. Was on offer for £10 this time so was a no brainier.

It sure helps but I was expecting more.

Hasta proximo cambio de aceite no oo usaré, ya q eche sellador de junta de culata y no se pueden mezclar. Pero conociendo la marca seguro q va de maravilla.

i ordered the product first time it was delivered, and it was great. but when i place an order for second time i didn't receive it, but thanks to the Amazon customer care that step into the issue and the seller refunded me back my money, despite all that i recommend the seller and the product and hopefully i will reorder the product again if need be

It’s amaizing. Just let the engine run for 5 minutes and the knock sound was gone

Good product
