I still use about half ounce per gallon evey 10-15K miles.......works as good as Chevron Techron for cleaning upper cylinders and injectors!!Originally Posted by justbob
In the old days (think carburetors) we would add a gallon or so of diesel to a full tank of 93 to lube up the carb and give the valves a bit of a solvent bath. Probably didn't really do anything but it most certainly didn't hurt either.
You probably walked away with cleaner injectors is all if she is still purring after two tanks of 93.

Just did it to my 2008 RAM HEMI (70K miles) and not only cured a flat spot in the accelerator but I also picked up a little over 1 MPG!!
