Throwing this in Advanced, since it's a more technical question than "what brand" or "how often"
So, after adding a bottle of Techron to my car (and ordering up some Red Line cleaner for down the road), I decided to ask the following of Chevron and Red Line (using each's product name of course):
--- Begin question ---
What is the best driving style to get the best results with Techron Concentrate in the tank?
Different situations such as WOT, extended cruising at low or high speeds, stop and go, and cold starts, all affect fuel delivery, cylinder temperatures, and dwell time of combustion mixtures (low vs high rpm). What I'm guessing is that some of these situations have potential for Techron to work more effectively. I'd hate to add a dose before a long highway trip when the same dose added before a week of city driving had more potential to clean up deposits.
--- End of question ---
A couple days later, both companies wrote back -
--- Begin Redline's answer ---
I am not sure which situation would produce better injector cleaning,
I would suspect that probably stop and go would be slightly better as
during shut down the detergents would work be allowed to saturate the
deposit and then clean it on restart. It will work either way and
likely the differences overall would be minimal.

The developmental work on Techron Concentrate was initially done in taxicab service and later using employee cars. None of the testing was such where highway mileage accumulation occurred after the addition of the Techron Concentrate. Thus, we have no data on highway service. It is our opinion that service where the vehicle is allowed to overnight soak several times so the additive has time to help soften the deposits works best. It is thought that refilling the fuel tank before it becomes empty stretches out the treatment and improves effectiveness.

The answers kind of surprised me - I didn't think that the overnight soaks would be seen as a factor, more than different cylinder conditions when actually driving the car. I guess that dose before the long highway trip _might_ not be the best time to do it.
At the same time, the answers clearly had an air of, "It just works, but we don't know exactly what conditions it does its work or works best."
I've been inspired by the poster who wrote all the tire companies a couple months ago, and will send the question out to more of the additive companies. As answers come in I'll post them in the thread. Hope this generates a bit of interesting debate..
