Im at the local jiffy lube and they have a special going on the gumout professional fuel injector and intake cleaner. It seems to be similar to the bg brand system. My question: do these really work? Is it worth it?
If it contains polyether amine, it's a good cleaner. Gumout calls it Regane. If it doesn't have that on the fact sheet, look for Stoddard Solvent. If you don't find either of those, it ain't worth havin'.
