Greetings All,

I think this post is one of many already listed here about this topic of adding tranny fluid to the fuel tank or filter for either cleaning the entire fuel system or injectors. As Scott mentioned tranny fluid does leave a formation of varnish when burned, I've seen those tranny inards before, but also wonder if burning it will have the same effect on the cylinder walls or injector tip, hence changing the spray pattern. Most trannies basically sit it the overheated fluid that allows the aluminum to soak in the properties that actually casue the varnish affect on the parts. Kind of wish that Redline and others promoting cetane improvers and injector cleaners to list what exactly goes into their bottles. If you have ever purchased the stuff, it kind of looks like it has grit in suspension to scrub the injector walls, but it doesn't quite smell like tranny fluid either. If anyone out there has the ingredients from their spies at Redline, let us know. For now, I'm not dumping tranny fluid into the tank unless there's good proof to do so. I've used a quart or so in my oil on the motor home to loosen up sticking valve lifter, and it worked fine but I wasn't driving with the stuff in the engine either.
