I am looking at getting some fuel injector cleaner from Costco, it Pro-Gard Fuel Injector cleaner with Techron. Is this a good additive for diesel engines and are there specific cleaners for gas and diesel or are they the same? I don't want to get it until I am sure its good for my truck. What do you guy's think?

I think the the Pro-Gard is for gas engines not diesels.

that is what I was wondering, I don't see anything specific for diesel. What do you recommend using?
