BlueDevil Products 00243 Stop Smoke & Engine Repair - 16 Ounce

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

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.

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 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.

I got this today, the shipping box was open, the bottle was open only half a bottle remained, its like I got someone else's return, not happy, next time I will just go t auto zone

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

Seems to be a good product would buy again. Helped but not a complete fix

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.
