Lucas Fuel Treatment, commonly referred to as Lucas UCL (upper cylinder lube), has a good following here. It seems to smooth and quiet engines/injectors/fuel pumps, and some people report a slight MPG increase. If you buy it in a gallon size, its quite cost effective too, and may pay for itself with any MPG increase.
I've used the Power Service's "Diesel Fuel Supplement plus Cetane Boost" additive in my Yanmar tractor, as well as my work's Yanmar-powered Clarke forklift and two Yanmar-powered John Deere Gators.
It really helped the Yanmar tractor - making it easier to start. I believe I had some water in the diesel fuel tank and this chased it out.
In the forklift, we didn't notice much difference at all. It's not the world's most happy forklift (it continues to run after you turn off the key!) to begin with and I had high hopes that were not met.
In the Gators, it seemed like the started a little quicker and ran a little smoother.
lucas is nothing but a snake oil...don't add it to your gas because it leaves deposits
coking..use a good oil...in the gas i learned to just use a good additive to your gas that has no oils in it...redline sl-1(no oil in this additive) bg's super chargell which is designed to be used with every fill up therefore bg 44k and cf-5 is never needed...in the past i learned the hard way i use to use neutra,some lucas,fp-60,and others with an oil base messed up my engine with deposits on my rings and tops..i don't use any additives in my oils and gas. i think lc in the oil is disaterous in my opinion..it just doesn't mix well which i have stated all along..
I disagree boxcartommie22, fuels today don't have near the lubrication properties that products that FP60 and LUCL have shown to be beneficial in this manor.
Just to be on the same page, are you talking about Lucas Upper Cylinder Lubricant [Lucas UCL]?
I use it a lot [or 2 stroke oil or a mix].
This is one product of theirs that is known to be good.
iam talking about the ucl for gas i don't use their oil additives....i know that i been using this stuff for alone time and had to tear down engine and found all this garbage around rings etc.use what you want.. i know why experts say do not add additives...unfortunately i learned the hard way...

Basically he puts three drops of acid into half tube of diesel, shakes it up, empties it, and hits it with a welding torch.
For the treated tubes, he fills the rest of the tubes with the additives, shakes them up and torches them as well.
The additive to fuel ratio is like 1:1. As this ratio, I am not sure if it proves anything.
I love LUCL BTW. Makes my 2.4L Camry run smooth and returns 33 MPG. (EPA 21/30). (Well the drivetrain is well tuned, tires are inflated, and I take it easy, helped too)

I have installed the codec but still I can't see the video.
Any suggestion ?
I would not buy anything from Lucas other than the UCL or their trans slip for a last resort on a tired trans. Seen dramatic improvements in engines running the ucl in gas and diesel engines over the years. Although I think the price for a gallon has got out of hand and seems a little overpriced for what it really is.
