Is Lucas Fuel contioner one of the best on the market for lubricating the upper cylinder and cleaning? I bought some and it is very oily. any comments?

Have used in Class 8 diesel, very pleased. Saw consistent .5 mpg improvement.

Have used in 71 Chrysler, helped with reformulated gas. Cut back from every tank to every second or third, does very well at helping hot soak & roughened idle.

Yes but is Lucas UCL a worth while product to use?

I use Lucas UCL every tankful mixed with FPC fuel catalyst. Unleaded fuel use requires a lube to replace the lube effect of lead. And during computer analysis during dyno recently operator commented on how clean injectors were (don't ask me how he read that). I have used Redline but very expensive here. Will do me till I find something better.
