>However ever hopeful I would like to know the website. I inadvertantly >deleted the E Mail with the website listed. Try http://www.fuelquality.com first. There you'll find the link to LV Petro site. Also Keith Wellington's email address and 800#. I'm sure he can answer your ? about biobor w/ Hammerdown. FWIW, my take after reading all of the test reports is that Biobor isn't needed on top of Hammerdown. Cheers, Steve ------------------------------------------------ Stephen C.
