All I did was one treatment using Shell fuel injector cleaner the other day and as I got down to about 50mi. left, a bunch of smoke started coming out of the muffler. I stopped the car thinking there was something majorly wrong with the engine or something. I even called my mechanic and he said the seals on the turbo could be shot and that I'd probably have to get a new turbo. All disappointed, I started the car up again, and magically the smoke started calming down until it completely went away. The car runs even better now it seems. I never used Seafoam before, but I heard what happened is similar to doing that? Did this ever happen to anyone?

 

I always use shell 93 octane (supposedly with that v-power cleaning stuff) but im currently about to get some lucas fuel injector cleaner tomorrow, and ill let you know

 

I have about 100 miles left on a bottle of Lucas, I will let you know what I get

 

Which also, how many miles are you guys seeing on a tank of gas?

 

i get around 280 from a full tank, but i drive short distance to and from school/work (around 5 miles one way)
ohh and btw i dont really run it down to empty LOL

 

I get around 400mi doing about 70% freeway. I could probably get more, but I usually fill up when the car beeps at me.

 

wow, you guys get way better than me. my 01 1.8tq tip, im getting only bout 240-250. i have the diode mod and all, but im not beating the snot out of it...grrr

 

im averaging 230 before the light beeps at me, then fill up.. How much of the lucas stuff did you use?

 

i recently got some of that lucas injector cleaner and fuel conditioner. the result was improved idle, improved compression, better fuel economy. Good stuff.

I want to try the lucas oil additive but i've heard you shouldn't add additives in audi engines. ???
