I noticed something in their FAQ that really irked me so I sent them an email with this as its body:
To whom it may concern:
I am not sure where your research is coming from in regards to the lubricity of such fuels as Biodiesel, but I suggest you brush up a little before making such statements on your website as:
Q: What Advantages Does EMP Have When Used With Alternative Fuels Such As Biodiesel?
A. When you use BioDiesel, and other alternative fuels, fuel economy and lubricity typically decreases. EMP has demonstrated superior results in increasing fuel economy and lubricity in alternative fuels such as BioDiesel.
Biodiesel has far more lubricity than straight #1 or #2 diesel alone. When mixed in quantities as small as 2%, the 2% blend of Biodiesel, even poor quality, ultra low sulphur diesel fuels can meet lubricity requirements for most any new diesel engine manufacturer. It is a foregone conclusion that at least in the short term, alternative fuels will be a stopgap measure to slowing dependence on foreign oil and supporting the domestic economy while also helping improve air quality. It is sad to see a company misrepresenting the inherent beneficial qualities of these fuels in order to sell what is, at best, a product that will do little to nothing to help consumers and only serve to lighten their wallets.
While your product may well be the be all, end all we are looking for, one has to suspect that it falls in the dubious category of "snake oil" which will soon find its way to the dusty top reaches of AutoZones and Advanced Auto stores nationwide, right alongside similar gimmicks like DuraLube, Slick50, etc. If this product did what it is claimed to, it would be plastered all over in the worldwide press and a government standard for every mechanized vehicle in use today. If such a miracle were to actually exist, why would vehicle manufacturers be spending millions on catalytic converters, egr systems, and constantly reworking existing engine designs to meet government emission specs? They could simply be selling this wonder potion by the barrel and making themselves and your company millions if not billions in the process while eliminating a lot of headaches.
If you want to join the ranks of the other scores of companies marketing a simple dyed petreoleum distillate in a fancy bottle that at best demonstrates a barely tangible response in a controlled lab scenario, be my guest. Free country and all that. If you can make a few bucks in the process, that's great too--we all need the money. Make all the hyperbolic claims about it that you want, and gloat over all the happy customers who are ecstatic with the product due to the everpresent placebo effect that takes place in individuals who spent a considerable amount of money on something they desperately hope will work. But please don't resort to making false claims and comments on products in the marketplace that actually hold hope and promise for the near future, despite what small drawbacks and perceptions (mostly internet based) they may have.
Here are a few handy links from reputable resources that can help set you straight:
