[Paragraph from Dave Stevens:] The prevailing wisdom seems to be that BG44K is an excellent, but very strong cleaner, really only appropriate for use on badly carboned/neglected engines, especially considering its cost. I mean, you don't need oven cleaner to do the dishes. You can try getting it through a friendly shop or auto supplier or you can try getting it from one of the auto e-tailers. Other top end/injector cleaners you may want to try are AMSOIL PI (through distributors like our Paul S), Chevron Techron (concentrate) and Redline SI. That's more or less the order of preference I've seen. Some of the house branded injector cleaners (like GM and Mazda) are reportedly as strong as BG44K. There are many other injector cleaners out there, some may be okay, especially for routine use. Just be sure to avoid the cheaper, older solvent based cleaners that might attack the fuel system and injector seals.



I'm not sure of the basis of the earlier statement. Or, for that matter, for the negative reputation of STP. Or, is that an STP product, different from what everyone is thinking. (Even FRAM makes some good filters, even if their bottom end product sucks.)
