In this video I tested Lucas Deep Clean. I use a mini borescope camera to look into the engine and see how dirty the engine is before the fuel treatment and then after the fuel treatment.
I followed the instructions on the container and Lucas performed a little better than Techron and Gumout. This is the 4th test in a series of fuel cleaner test I will be performing to see how fuel cleaners work and if they actually work.
Here is the fuel cleaner I used: http://www.amazon.com/gp/product/B003JTYGPO/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003JTYGPO&linkCode=as2&tag=chri0e2-20&linkId=G7HYTNQFS4A74QOA

    Wish you had checked the mpg before on a tank full ! Then w/Lucas !! I get 15-30 mpg better on a 28 gal. fillup !
    Our dieselโ€™s do way better !!

    Think it will help an intermittent inefficient catalytic converter code? I just failed smog for high NOx ugh. I had a loose spark plug 4.6 Mustang 2V LOL so I'm thinking I had poor combustion on that cylinder for awhile. Right before it blew out it threw a code for that same cat bank. It eventually popped out without damaging the threads so I just screwed it back in there.r Should I run the product during or just before the emissions test?

    Add 1/2 cup of MEK ( methyl Ethel Keytone), a strong epoxy thinner, to each cylinder head by removing the plugs. Let sit several hours. Fire that bad boy up. Clean as new.
