There was a discussion here before about it and I believe the majority liked Red Line products the most, as did I.

I have used both RedLine and Seafoam in the fuel tank. Both work great and cause no troubles. Redline costs about $15 per bottle and Seafoam costs about $8. Seems Redline could be a better product. There was a discussion on these two but the search function is not available at the moment. I will edit this post when search comes back online.

EDIT: here is the link to the thread:

I use BG-44K, although it is not considered the best anymore by some people.

You may find that a pressurized injector rail cleaning at the dealer may be best - remember to ask for that and not their "add the equivalent of BG-44K" injector clean service.

I would only use Redline SI-1 Fuel injector cleaner. I would not trust anything other than motor oil in the crank, or anything in the brake booster. Details are in the thread listed above (thanks Larz!)

A fuel injector cleaner is a waste of money. First fuel injectors have become very reliable. Second, all fuels contain detergents that keep the injectors clean so they can meet the EPA emission standards. If you buy tier 1 gasoline you will get more detergents than the EPA requires. I buy only brand name gasoline which exceed the EPA requirements. Shell for example has 5 times the mandated amounts.

Years ago a fuel injector cleaner made sense but not now. When was the last time you heard about a fuel injector that had to be cleaned or replaced?
