Poured into the engine oil as directed; effect showed up after a short drive. What I noticed: Exhaust smoke dropped significantly and quickly. Easy to use — pour and drive. Heads-up: This is not a repair, more of a temporary aid; results depend on the root cause. Monitor oil level and follow the label. Worked right away for me and reduced smoke noticeably.

My mower was smoking badly from wear. It was so thick at times that I could not see ahead of me. One treatment ended the smoke. It's not fixing the engine, but it is allowing me to mow until the engine gives up the ghost.

I have an old Kubota rtv 500 that smoked ridiculously. Couldn't go to the woods without being seen for miles. I put this in it and it smokes when I first start it in the morning and then never smokes again. I'd recommend this product for any small engine that's smoking. I've been an automotive mechanic for 35 years and I didn't expect it to do anything but it works. Don't know about car engines but it definitely worked for me and I buy it all the time.

it made my problem worse, alot worse. The smoke came out thicker. And yes, I had a mechanic do it for me. He said it should have worked in theory and it seemed to be at first. So maybe it was a bad bottle. I don't know.
