I did and my troubles went away. Isn't the internet wonderful that you can just jump up and buy some product you never even heard of before and it fixes your problems?

I was hopeful for this product as someone I know claims it works. My engine has 200K miles on it. Runs great except for the lifter noise. I've tried two bottles now and it quiets the engine, but a couple weeks later the noise is back. Maybe you will have better luck, but my advice is don't waste your money.

WOW THIS STUFF IS MAGIC IN A BOTTLE. I HAVE A 1998 OLDS 88 WITH 40K MILES WHICH IS LOW FOR THE YEAR. I WAS IN A CULVERS DRIVE THRU AND HEARD THIS NEW LOUD TICKING NOISE THAT WAS NOT PRESENT PRIOR AND WAS OH GREAT, WHATS THAT, LIFTER, TIMING BELT, WORK PULLEY. WENT TO ADVANCED AUTO PARTS AND ASK THE GUY TO COME LISTEN TO SEE WHAT HE THOUGHT. HIS OPINION WAS A LIFTER MAKING NOISE. WEENT BACK INSIDE AND LOOKED AT PRODUCTS AND THE GUY SAID VALVEMEDIC IS MADE JUST FOR THAT AND NOT LIKE OTHERS PRODUCTS THAT DO A 100 THINGS. BOUGHT AND POURED INTO CAR. DROVE THREE MILES DOWN THE ROAD AND STOPPED AT RED LIGHT AND NO MORE NOISE. DROVE ANOTHER 15 MIN. NO NOISE. DROVE ANOTHER 30 MILES HOME AND NO NOISE. WOW WOW WOW.
