Here is a copy of one of my posts in the Venture forum I posted back in April of 2005. Hope any info in the post can help you make your decision,"If you are going to add any cleaner in your tank DO NOT put it in an empty tank. Put the cleaner in a full tank of fuel, or as you prepare to fill the tank at the gas station. Fuel injected vehicles use an electric fuel pump in the tank. The pump passes the fuel through the pump windings to cool the pump. The fuel cleaner can eat the varnish insulation off the fuel pump armature windings and damage the pump, or rendering it useless. Auto manufacturers make sure that the additives found in pump gas won't hurt the pump, but do not run any tests with the aftermarket cleaners. Sometimes the apparent damage to the pump from adding the fuel cleaner on an empty tank may take a few days to manifest itself, thereby posing the risk of becoming stranded. Use the fuel cleaner as little as possible. Constant unneccessary use can accelerate problems with fuel pump failure. Not all aftermarket fuel additives are harmful, but why take the chance in discovering the one you are using is one that will eventually cause damage?"
BTW, when I do use fuel injector cleaner, I now use Lucas brand products, a couple of my other mechanic friends use it and told me about it, and it seems to work out all right, and it's cheaper than BG products
