I also used to use Techron in my CIS cars, those purchased new included, per the parts departments' suggestions. I even did it pre-oil change per the warnings on the Techron bottle.

I never had measurable results.

After my first dose of Redline, I had almost new-running cars, I have never gone back. I am very glad that I did not continue with the parts department folks at Mercedes & Audi suggestions.

As they say, "your mileage may vary", but after 33 years with CIS cars I have tried almost every snake oil around, have always bought premium fuels from major-brand stations, and this has been the only solution to low-volume spray pattern issues in CIS injectors. Admittedly, I no longer have any CIS cars, sold my (from new) '85 quattro last year, was my last one, with over 200,000 miles engine never opened / injectors never out. Idled and ran great.
