A little more dirty UOA at first. IMO, the crud will for the most part be blown out for what there is that will be removed, the rest will absorb into the oil, but Lucas will not get "That" clean.... but it does help.
As far as MPG: I donno how much LUCL will do, my additive did about 7% (if I recall correctly) in my engine. The only way that you could know is if for the period prior to using LUCL you kept accurate records.
If you keep detailed records of the MPG (including the amount of additive), you can judge any product that you add or subtract from the auto to see over the long run if was in effect helping your cause or creating a hinder.
In the future you may want to use the back of a legal pad (what I use on a clip board) or whatever, to keep a long run ( I get about 10K per side - so 1 pad can get about 20K ):
this is what I do: as an actual example,
6Sh 366925 223 1.579S 8.915875 4oz-oil 25.011566
4Sh 373678 230 1.409R 10.00225 8HrsIdle 22.9948262
The first # and letters are the ounces of fuel additive and the type of gas (shell exxon)...
Then total miles, and miles for that tank...
then Cost of gas+Grade and # of Gal. including additive.
Then comments followed by MPG and sometimes more comments.
Then every 3 or 5 K you can run a total of all gas added and all miles traveled, and figure a better # on MPG. Giving more weight to the periods
that there are no Auto problems or oil problems, than those with them. Giving more weight to the last Oil change than the recent trend of good auto. Etc.
If you do this long enough, you may eventually change filters, oil or other things using this data as a guide (well maybe only me). IMHO -
You can tell by three constant drops if there is something wrong with the car; Two is an indication, several sets of TWO are telling about a future problem, or how much of what additive is working/not, etc.
