15-20% off reducing friction??????
You might reduce friction by that amount but to get that much more MPG you have to reduce friction a huge amount (no friction). Oil does a great job of reducing friction. also friction losses are not the FE killer. Its the design of the ICE that kills MPG, we get 25% of the BTU's in gas as usable energy the rest is lost as waste heat.
Show me the hard numbers or this is snake oil or BS. Sorry this just seems out of the realm of possibility.
