Rislone 4416 Ring Seal Smoke Repair - 16 oz.

I have a '99 Jag XJ8 with 100K mileage. Awhile back, I started seeing blue/white smoke out of the tailpipes at start up. My Jaguar specialty mechanic diagnosed it as worn valve seats, which is not an inexpensive job on a Jag. Since this caused me to lose a half quart every 2 weeks or so, I started adding this in on a 50-50 ratio along with the replacement motor oil. After about 6 months (or 4 or 5 bottles of Rislone), I am smoke-free. So, given I spent about $50-60 on this instead of $1500 on a valve job, I am pleased. While it says "ring" seal, it worked for me on worn valve seats as well.

I own a 55 year old two stroke motorcycle that suddenly started smoking when idling.I tried this stuff; idled the engine for 5 minutes per the instructions. IT WORKS! Minimal to no more blueish smoke! Worth every penny I paid for it!

The smoke at start dud not completely stoped.

it didn't work, I still have blue smoke from the exhaust until warmed up.

I was told my 2010 GMC engine was burning oil, but not leaking on the ground. As a senior woman, I began to look around for a solution. Came across this on Amazon, wasn't sure so I called the company. They gave me great advice, which product of theirs to use. I only added it about a month ago and I don't drive a lot of miles, but so far it seems to be working for me. He did tell me I should be able to get another 1 or 2 out of my vehicle with this product. So glad I got it.

Added to oil in a 72 ezgo truckster dump Cart.. was burning a quart of oil every few days. After adding it completely stopped the oil burn.. really great product.. will only work if rings are gunked up.. will not fix if rings are worn bad and have compression loss.

Kinda worked. Thickens oil

Everything they claim this product it does
