BlueDevil Products00243 Stop Smoke & Engine Repair - 16 Ounce

Look, I know it's not a cure all, my engine will still need to be repaired, but it stopped the plume of smoke I was getting every 3rd start up, the oil leak has so far gone away, and I can hold out and save for that big repair or more likely a newer car. THANK YOU.

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.

Didn't work. Followed directions. Nothing changed

Blue devil is my go to for anything I need to fix like this and it always works

Mechanic friend told me about this product and I’m impressed. Just what my engine needed and love Amazon had it because most of the auto parts stores don’t carry this product.

I used this on my Chevy pickup because it was smoking when I turned it on after I had the motor fixed, and it helped.

It took a few miles to eliminate the smoke from my 4.7 Jeep engine.

Put this in my 23 year old goof cart that smokes. The smoke is slightly less but need to drive it more. I think valve guides are bad so not expecting miracles.
