I did a quick search and didn't see a title like this.
Fuel additives for cleaning the fuel system, do you use them?
What brand and how often do you use it?
Have you noticed a difference w/ and w/out using it?

Bottle of Techron every 3000-3500 miles. I exclusively use Shell or Chevron in the TT, so it's probably overkill, but what the heck

Thanks, this is the kind of info I'm looking for.

I use techron every couple of months. I have also heard very good things about the BG product called 44K for cleaning. I'm going to try that next.
