I was thinking about using a fuel injector cleaner additive on my '96. Any testaments on additives? Not just FI, but also other additives.

 

Seafoam

 

Seafoam does have a strong stoddard solvent that will clean the fuel system.

That being said, my favorite fuel system cleaner is Techron, by Chevron. I use this product about 3 times a year as a preventive.

For fuel systems that are symptomatic and you want something stronger, BG44K cannot be beat. It is expensive but I have had some really good results with it.

Other than that, I don't use additives as 1)you most likely don't need them and 2)Most don't work as advertised; snake oil

 

The best way to clean your injectors is to pull them out and send them for refurbishment. There are quite a few options on my side of the pond, but it usually works out at about £10 an injector with a before/after spray pattern chart to show you how much you gained.

 

Another vote for Techron for minor cleanups and the BG products for something stronger.
