there are so many different views on fuel injector cleaner as reg. maitenance. I used it because I bought a neglected car that badly needed all the fluids/systems cleaned out.

Others have made the point that if a car is in tune and you run good, premium gas through it, there should be no need for extra cleaners.
Techron (in a bottle) is apparently just a higher dose of the stuff Chevron already adds to the fuel.

Then again, if a car is in tune, running well, I don't see how a bottle of Techron every 3-5000 miles hurts anything. A lot of people do report good results with the Techron.
