Actually, you'd want to use it a few tanks of gas BEFORE each oil change. The stronger techron stuff purportedly can thin out your oil. The fine print warns not to use it more than x-times per oil change.
The regular Techron injector cleaner is just a watered-down version of the Techron system cleaner. Supposedly, it's so dilute you can use it every fillup.
