Lucas Oil Deep Clean Fuel System Cleaner, 5.25 Ounce (10669)

This product is absolutely amazing and does clean the system. I can just tell after using it that my car is running better and smoother.

This product worked for me. If you need or want a fuel system chemical cleaner, give this one a try. I use this, and other Lucas Oil products in my vehicles.

This product works awesome. I buy a new one every single oil change(8K miles). Makes your car run smoother pretty much right away. Great fuel additive!!!!

I had an "accident" on my GSXR-1000 2005 (I was riding like an idiot, really), nothing major, just cosmetics, but it took me more than a month to get my bike a new set of fairings. After i got it ready, I noticed that between 7000 and 8000 rpm's my bike kind of 'jerked', like losing power for a third of a second or so. It was almost predictable.Mechanics are expensive so I decided to give this "snake oil" a chance. Bought two bottles and poured some of it on every full tank. My gixxer small tank so a single bottle took around 5 or 6 fill ups.By the end of the first bottle the 'jerking' was gone. My bike feels smooth all the way to the red line.I cannot say for sure that a bottle of Lucas Deep Clean fixed my bike, maybe it was just residue that got accumulated and regular riding got rid of it. I'm not a mechanic, I'm not qualified assert anything, I'm just a happy rider on a healthy bike.Now I use it once a month, just as a preventive measure.

My car's engine was starting to "stutter" a bit when accelerating, nothing major but noticeable. My theory with "repairs" is to start with with simple and cheap. Added a bottle to my gas tank, car now runs smoother than ever. I'm a believer! I'm now adding to all my other engines too.

Good product good price

Works great for the proce
