I bought a few years back a case of ''Power Service'' diesel fuel conditioner on special and still have 4 bottles leftover. Have just notice there is a date on the bottles. Could this be an expiry date or manufacture date? I just can not remember the year that I bought them, but had to be around that date. I cannot imagine that their is an expiry date on conditioner, but then again I've see weirder thinks. I've check at my local ''auto center'' and the new bottle of PS have no date on them. Would like to know what you guys think before continuing using it.
