While watching an info-tainmeant car show, I saw a very good simile for the different types of fuel injector cleaners. The types that have petroleum distillates (they are usually listed for every tank or frequent use) are like brushing your teeth twice a day. They are for preventative maintenance.
The heavy duty cleaners with stronger solvents are like going to the dentist to get the plaque off. If you want healthy teeth and injectors, do not get them mixed up. And if you are having problems from build up along your gum lines or on your injectors, you start with the heavy cleaning, then use the preventative cleaning or daily brushing.
So for those who can not see the little print on the bottles or did not pay attention in chemistry, STP and Seafoam are for regular use. B12 Chemtool and the dealership stuff that often comes in metal cans are for when you need a deep cleaning.
