The old audi seems to lack the zip i think it should have.
All the tuneup parts are fresh, the miles are low and several of my car mentors said i should add some Lucas injector cleaner.
So i bought some, having never used it before. I expected a powerful solvent but it's an oderless oily substance.
It seems to be working but it boggles my mind that something mixed at 100 to 1 with gasoline could have any real effect on the injectors.
maybe someone can 'splain it to me.
Maybe I need one of those Matt Collie "molecular" explanations.
Thanks

It's gonna take a lot of Adderall to get this thing right.

I have bought the truck stop Lucas gallons and refill the little Lucas bottles for dispensing. I assumed its a lubricant and stops the adhesion of crud as well as making the injector move better. I've heard a lot of Diesel rig drivers tell tales of it fixing problems on big rigs and busses. I don't think it will harm or disolve rubber parts. That's my theory-- any scientific backup out there?

Dave,
Something happened to my first answer, so I will try again.
As to the 100 to 1 thing.
Some of the oil injected 2 stokes run a greater than 100 to 1 at some times.
Every try to match paint?
Forget the salt in a recipe?
Mix a dye for color?
I never did any testing with Lucas Oil products, but we did run some on the Techron line for Chevron. We were supposed to run engines with things that were known to foul fuel systems. We were not supposed to analyze it.
It did what it was supposed to do and some unauthorized impromptu testing by some technicians gave similar results.
You would not want to add a solvent to an automotive fuel system because all the elastomers (rubber parts) will absorb some of everything and the effect is cumulative. This can make those parts not perform as expected. Most solvents can attack some elastomers to greater or lesser extent and that is just not a good idea at all.
Injector fouling seems to come in two types. Things in the fuel that stick to the parts that nothing is supposed to stick to, and residue of fuel that has been heated and largely evaporated. This is not coking. Coking is when a hydrocarbon gets really cooked to be about nothing but carbon.
Remember - you asked....
At least this (Techron) product was a solution of detergent (polar and non-polar in the same molecule) and Octane (real octane - the liquid), probably chosen for its predictability. The detergent would drag some of the residual back into solution and it would attack the sticky stuff and make it mix into the passing fuel as well.
Theoretically - The detergents that are required to be blended into pump gas is supposed to have the same effects, but with the margin on motor fuel being what it is (Zilch), they are going to hold any thing extra to a bare minimum.
From the sniff test I did some years back, I suspect that the Lucas products are the same.
Hope that passes for an answer.

Thanks Matt, that really does make sense and I love the analogy about salt and paint.
Probably would have been an even better explanation had i spelled your name right.

I understand my responce does not answer your original question, but at times I still feel the need to give my 2 cents worth. And yes, I do realize that my 2 cents,may not be worth that much.
The following is how I used to clean injectors.
I got an injector connector at jump yard. It was maybe 2 feet long. I could plug in injector, and tap the wires to a battery to fire injector.
Hook up marine gas can(hose with pump bulb)to injector. Put a little kerosene in gas can. (this was done with injector removed from car)
I would pump bulb to build up pressure, then tap connector wire to battery to fire and push fluid thru injector spraying into mason jar.
pump up, and do again.
Usually after 3 to 5 times I could see spray pattern improve.

Back when I went to G.M. training, we removed the injectors and put them in
an ultrasonic immersion cleaner. Then put them on a test fixture that had a
paper target with concentric rings on it. The fixture cycled the injectors
and they sprayed onto the paper target. Pass/ fail kinda deal. Final
cleaning with R-12 and reinstall or replace.
